Abstract

A device for a game of chance with the possibility of winning equipped with at least one (drawing) chamber (1), which is provided with a drawing system which receives the game elements (7, 8, 9) previously mixed , and from which, during a draw, one of several game elements must be drawn. In the chamber there is a set of game elements which can mix freely by means of a suitable system (2) during a mixing phase in the chamber. The set of game elements comprises at least two game elements of different designs, one of which must be drawn during drawing by means of a drawing system and must be brought into a drawing container (11). The drawing device has a number of intermediate containers (14) arranged in the chamber (1) corresponding to the number of playing elements of the assembly to suitably receive a playing element after mixing, these elements being blocked with a lock (17), during an initial drawing phase with the exception of an intermediate container (14) to prevent the distribution of a game element into the drawing container (11) assigned to the assembly. During a second drawing phase, the game element which is located in the unblocked intermediate container must be guided towards the drawing container (11).

Description

Gambling machine

The invention relates to a gaming device with a chance to win, with at least one (drawing) chamber, which is equipped with a game body after a mixing process receiving device, and from which one of several game bodies is to be drawn during a draw.

As there is a wide variety of games of chance, there are also various types of gaming devices which are interesting for a player in accordance with the possibilities of winning and the design of the game process.

The criterion of all games of chance is that chance determines the outcome of the game. A problem with all gaming machines is therefore to ensure the randomness of the profit-determining events. The higher the payout, the stricter the scale to deal with this problem

HBSATΣBLATT Quote for a gaming machine is, since a systematic deviation from the statistical mean of only a few percent can lead to the unprofitability and thus the usability of such a machine.

It is also common to all gaming events that many players treat them with a basic mistrust, which they particularly upset when they lose, ie when an event they favor and which they have relied on does not occur. They then often suspect an inadmissible influence on the course of the game to their best advantage. This distrust can only be completely dispelled in a game of chance (device) if a player can convince himself that a control of the drawing process which influences the course of the game (this is known to mean the process in which the result of a game is determined) ) is not possible, e.g. if a drawing in the free play of the forces takes place in a mechanical manner, such as this is the case with roulette.

In the present invention, therefore, the two aforementioned aspects "guaranteeing the randomness of the drawing results" and "trust of the player in the game conditions offered" are given particular consideration.

The best-known gaming machines are probably the so-called "one-armed bandits", in which several reels with symbols on their outer surface are each braked at a random point in time, the symbol

CRSATZBLAF Combination of the symbols of several rollers that then appear in a viewing window show the drawing result. The random deceleration of the rollers is controlled today by electronic random generators, whereas previously complicated electro-mechanical devices fulfilled this task.

The typical thing about these gaming machines is that they have a large variety of game results, draw results, but only a small number of which are profitable.

As a rule, these gaming machines have four reels, each of which is equipped with about twenty symbols on its outer surface, all of which can be imported, so that four reels with twenty symbols each allow 160,000 (= 1/20) combinations of reel positions. In total, only about ten to twenty different symbols are used, which occur in different frequencies. In accordance with the different frequency with which the individual symbols appear, the possible symbol combinations are imported at different frequencies. A small selection, usually about twenty, of these possible symbol combinations are profitable, the vast majority of them are not, so that it is only possible to win on average in every seventh game.

The player's stake always applies to all winning combinations, he cannot bet on certain winning combinations as he likes, so he can not be targeted, i.e. play methodically, by system.

The preparation of the profit plan is based on a complicated calculation which the player cannot follow, which is why the payout ratio cannot be calculated for him. The advantage of these devices for the The player is that the win in a game can be several thousand times the stake.

In addition to these gambling machines equipped with reels, there is the group of those who simulate the classic game of roulette and are called the roulette type. These gaming machines differ from the roller machines primarily in that they only have a very limited number of gaming results, all of which are profitable. With these devices, the player can bet on certain game results and the devices must be equipped with a setting table.

The advantage for the player with this gaming device is that the payout ratio is easy to calculate and systematic gaming is possible. The disadvantage with these gaming devices is that the highest win cannot be greater than e.g. with 36 boiler numbers 35 times the use, that is, in contrast to the thousands of times in the roller devices is very limited.

The control of the recording takes place via electronic random generators and is completely hidden from the player as a process and is no longer understandable to him.

Different from these two groups of gaming machines are gaming machines, in which freely movable game bodies are used, and the drawing takes place more or less in the free play of forces, which the player can follow and understand. This type of play, i.e. the determination of the

REPLACEMENT LEAF The result of the game or the drawing is fundamentally advantageous for the player, if only because the drawing process can captivate their interest. This group of gaming machines with freely movable game bodies must therefore be discussed in more detail with regard to the present invention.

From DE-PS 1 574 184 a gaming device is known in which the physical at least partially different

/ * _. designed, spherical game bodies are used which are each more or less freely movable in a drawing chamber during a drawing process and hit baffles which are spatially differently oriented towards the drawing chamber wall during the drawing process, so that they randomly deflect their movement path from top to bottom during the drawing process be, with a given number of game bodies in a drawing recording and thus determine the game result.

A disadvantage of this known gaming device consists first of all in that the differences in the game bodies can be determined largely reliably by corresponding equipment of the game device itself, if correspondingly sensitive recognition organs are provided, but not by the respective player.

A further disadvantage of this known gaming device lies in the relatively poor readability of the gaming result, which results from a design-related vertical arrangement of the drawn gaming bodies in the drawing receptacle.

HBSATZBIATT Further disadvantages of this well-known embers, .— _F _, lie in the complexity of the variety of physically differently shaped game bodies (and at the same time also in a certain confusion of the game and, in particular, drawing process for the players), in the organs for the realization of sensitive recognition effort and in the design and last but not least the sequence of the mixing process forming part of the drawing process.

In order to create suitable detection devices for such gaming devices, it has been proposed in DE-PS 22 16 635 that a light source and, as actual detection elements, photo transistors are assigned to the detection area, which are arranged displaceably over the length of the detection area, the light source preferably being located over the entire area Length of the detection area extends.

The subject of DE-AS 2803 894, on the other hand, focuses on an improvement of the mixing process forming part of the drawing process in such gaming devices and suggests that the game bodies are swirled by air during the mixing process in the drawing chamber. It should be noted, however, that air from other mechanical mixing means, such as baffles or the like designed and arranged in a suitable manner. fundamentally does not differ, so that by means of a mixture of the game bodies through a gaseous medium such as air, in principle ultimately no qualitatively better game result can be achieved with regard to the desired randomness.

REPLACEMENT LEAF

ORIGINAL 1 A great advantage of such gambling devices is the fact that the profit-determining events basically take place as it were in the free play of the forces, so that the player can also observe and understand their course in this respect; that the profit-determining events do not occur in a manner unknown to the player, as is the case with the electronically controlled devices or the still electromechanically controlled roller devices, in which the mode of operation ensures the neutral randomness of the profit-determining events Devices remain hidden from the player because of the design of these devices.

From DE-OS 25 03 278, a gaming device with a game process that is essentially freely movable has become known, which is also a ball, which in the case of this previously known gaming machine is not somehow different, but is of identical design. Due to the use of identical game bodies, there is accordingly no need for any special recognition organs with which, after a drawing, it can be determined (automatically) what type of game bodies are drawn.

In the gambling device known from DE-OS 25 03 278, six game balls, for example, fall one after the other into one consisting of impact pins

REPLACEMENT LEAF Baffle-provided vertical playing field of a certain width, which is provided on its side edges with bands which taper downwards and open into two receiving shafts, each of which has a correspondingly marked receiving shaft is a so-called hit shaft. A counting device consisting of two step-by-step hit counters works in such a way that one hit counter counts the hits of the first three played game balls and the other hit counter counts the hits achieved with the last three game balls. This previously known gambling device therefore has the advantage over other gambling machines described or at least indicated above that the drawing and thus the outcome of a game take place in exciting yes-no steps which can be observed for the player.

The creator of the gaming device according to DE-OS 25 03 278 has developed or varied the subject matter of this document, in particular for installation in casinos, in such a way that no longer six balls in succession through one and the same playing field (= drawing chamber) and then through one of two receiving shafts (= Zieauf hme) fall, but there are six in this further developed gaming machine (also with deflection chicanes)

REPLACEMENT8LATT There are six playing fields (also each with deflection chicanes), in each of which a spherical playing body is present or is introduced into the respective playing field, the spherical playing bodies during the drawing process in each case - as in the gaming device according to DE-OS 2503 278 - fall into one of two receiving shafts assigned to each playing field (= chamber), of which in turn only one (appropriately marked) receiving slot is a hit slot, so that in this way not only a better presentation of the game or drawing result and A corresponding control is given afterwards, but also a (considerably) faster game flow, so that with such a gaming device per unit of time, considerably more games can run than with the gaming device according to DE-OS 2503 278, which is obviously considerably more advantageous for the bank .

While this previously known gaming machine, which has been further developed from the subject of DE-OS 2503 278, is to be mentioned as an advantage that, with a high payout ratio of approx. 94%, profits between two and sixty times are realizable on all chances that the profit-determining events for a player are observable, manageable and accordingly understandable and also interesting, since they consist of Y-no steps taking place in the free play of the forces, and that the profit plan is also transparent and the payout ratio can be calculated, whereby as a further advantage would be added that every game outcome is profitable and therefore leads to a profit if it has been set by the player, Part of it would be mentioned that the game result is not clearly recognizable at first glance, as this is desirable at least from the player's point of view. Further disadvantages include the relatively complicated play body guidance and the high construction costs.

The main disadvantage of this previously known game device is, however, that the spherical game bodies (\ during drawing can be subject to certain constraints which lead to preferred drawing results which do not correspond to 100% randomness.

The present invention is accordingly based on the object, while avoiding or at least reducing the aforementioned and further disadvantages, of creating a gaming device of the type described at the outset, that is to say a gaming device with freely movable game bodies, the gameplay of which is interesting and exciting for players and thereby for the The player is transparent and can be controlled accordingly, in which not only each individual game should be profitable, which allows the player to play in a targeted manner, but also high individual winnings of several thousand times the stake should be possible, furthermore despite the preferably exclusively mechanical design of the Drawing process systematic errors, ie any influences restricting the randomness of the game results should be avoided with certainty, so that a high payout ratio increases for the benefit of the player in calculating the profit plan unde laid In addition to these advantages, in the interest of the player as well as and above all in the interest of the bank, a relatively fast game flow of a single game should be possible, since with a high payout ratio the interest of the bank is only preserved through a high turnover.

As a solution to this problem it is provided according to the invention that in the chamber (of which there are preferably several, as will be explained in more detail below) there is a group of game bodies which are to be mixed during a mixing phase by means of a mixing device and during the mixing in the chamber are practically freely movable, and that the group of game bodies contains at least two differently designed game bodies, of which during the drawing process a game body is to be pulled by means of the pulling device and fed to a pulling receptacle, the pulling device being a number corresponding to the number of game bodies in the group has (game body) intermediate receptacles arranged in the chamber for receiving a game body after the mixing process, each of which during a first drawing phase, ie an intermediate phase after the mixing and before the actual final drawing process, with the exception of an intermediate shot against a game body being released into the drawing slot assigned to the group, are blocked by means of a lock, the game body located in the unlocked intermediate slot being the Draw intake is to be fed.

REPLACEMENT LEAF As has already been indicated above, in the gaming machine according to the invention there is preferably not only such a mixing and drawing chamber, but in a highly preferred embodiment the gaming machine has six such chambers, each of which contains a preferably the same group of gaming bodies , an embodiment with four game bodies in three types has been found to be particularly useful, so that two game bodies are identical to one another.

The drawing process in this embodiment of the game device now consists in that a game body is drawn in each of the six chambers. The six game bodies then drawn represent the game result, which is evaluated according to the number in which the individual (here preferably three) types have been drawn.

The individual varieties (as will be described in more detail later) are identified to the player by different colors and are supposed to be yellow, blue and black, the two game bodies being the same

R ^βÄ TZBLATT should be black. Drawing results can then be, for example: 3 x black, 2 x blue, 1 x yellow, or: 6 x black, or: 5 x yellow, 1 x blue, etc.

The mathematical relationships are now easily seen as follows: The probability that a black game body is drawn is 1/2; the probability that a yellow game body is drawn is 1/4; the probability that C will be drawn by a blue game body is 1/4. The

Probability that six yellow game pieces are now drawn in a game 1/4 = 1/4096; the probability that six black game pieces are drawn is 1/2 = 1/64; the probability that three black (and three other) game pieces are drawn is 20/64. The winnings that could be awarded for these game results, for example, could be in the above order: 3800 times, 60 times and 3 times the respective bet.

It is therefore clear here that a wide range of profits are to be offered in the procedure according to the invention, and that above all the requirement of the invention task can be fulfilled to make individual profits possible in the amount of ^• several thousand times the stake.

Which is in the preferred embodiment of the game apparatus with six ^chambers' for determining the highest gain Einzel¬ relevant mathematical quantity 1/4096 = (1/4) depending upon the two factors 4 (= number of Spiel¬ body per chamber) and 6 (= Number of chambers). These two factors are of course in principle arbitrary ^~ changeable, so that in another embodiment

_eB 8ATZ8 » ^ATr of the game device with more or fewer chambers and / or more or fewer game bodies per chamber that would also be intended according to the invention.

The preferred embodiment of the game device with six chambers with regard to the requirements of the task of the invention has the following advantages: individual winnings amounting to several thousand times the bet are possible for the player.

The conditions of the individual draws are very simple and easily understandable for the player. Only three drawing results are possible per individual drawing (per chamber) (namely black or yellow or blue), and the probability values (namely 1/2 and 1/4) according to which they are to be expected are immediately understandable to the player. Accordingly, the player easily understands the achievement of the (overall) game result, and the payout ratio can be calculated for him. The fact that two of the four different game bodies are the same makes it possible to combine all possible game results, which are all profitable and therefore betable, in a very simple way into a few betable chances and a simply structured one, the player completely to draw up an understandable profit plan, e.g. could look like this :;

6 x yellow 3800 6 x black 60

6 x blue 3800 0 x black 60

5 x yellow 200 5 x black 10

5 x blue 200 1 x black 10

4 x yellow 28 4 x black 4

4 x blue 28 2 X black 4

3 X black 3 The payout ratio would be approximately the same for all opportunities and would average around 93%. According to the invention, the game bodies are preferably spherical, because balls are firstly simple (also easy to manufacture) bodies and secondly easy to mix because their surface has practically the same properties at every point. Nevertheless, of course, other game bodies are conceivable and usable for the gaming machine according to the invention, in particular rotationally symmetrical game bodies of another type or the like

Game balls can be made easily distinguishable by different colors and are clear to the player, and there are also electronic color recognition elements with which the recognition organs of a game device could be equipped. However, such electronic color recognition elements are now extremely unsuitable for use in the game device according to the invention, because they can only be set to specific color values under specific light and reflection conditions.

The color values of the spherical surfaces are changed solely due to the unavoidable roughening of the spherical surfaces in the course of the operating time of the appliance due to their contamination by dust and abrasion. Shielding against changes in light conditions and / or against manipulative effects by means of light, e.g. colored light, would only be achieved with great effort and maybe not at all satisfactorily.

REPLACEMENT LEAF It should be emphasized here once again that freely movable playing pieces that are physically different, do not have as ^~ mix. In the case of, for example, four game elements per (mixing, drawing) chamber provided according to the invention, these four "game elements in an end position after mixing do not adopt every possible spatial arrangement with respect to one another in a combinatorial manner. Their spatial position is also constant during mixing Chamber is not purely coincidental, but co-determined by its physical nature, so that drawing results that would have to be qualified as 100% random are not readily possible, neither when pulling from an end position nor with "flying" pulling. Such results are even less to be expected with "flying" pulling, because in this case the physical difference between the game bodies has an even greater effect, for example through the mutual displacement of the game bodies (as a result of their physical difference, weight, size, shape or surface quality ) at the moment of pulling, which additionally creates a safe Pulling (ie that a game body is actually always caught and safely picked up by a receiving organ) becomes problematic.

When pulling from a rest or end position after mixing, which is preferred for these reasons, the four game bodies which are preferably provided in the intermediate devices already mentioned, which represent an essential feature of the invention, now occur in one in the game device according to the invention Such rest or end position after mixing does not occur with the same frequency in every combinatorially possible row, but preferred orientations arise in the (four) positions of the row, so that if this row is continuously drawn from any particular position, the Draw results are not absolute

REPLACEMENT LEAF random, but also depend on the drawing position you choose.

The mixing described here is not unnecessary, and the arrangement of the four game bodies in the intermediate shots after mixing is also random in that s is not predictable in individual cases. In the present invention, however, it should be ensured that the scheduled evaluation of the possible drawing results can all be based on the quantitative composition of the varieties of a game body group - an assessment that also corresponds to the natural expectation of the player - but this presupposes that all game bodies In the end, they are often drawn because you can only predict that, for example A type A of game bodies that is used twice in a total group of game bodies of different types is drawn twice as often as a type of game bodies that is only present once in the overall group.

If the drawing results are exclusively random, the prerequisite is met that all game bodies in a group are drawn with the same frequency. Conversely, one can say: If all game bodies of a group of freely movable game bodies are drawn with the same frequency, then the drawing results are solely dependent on chance. According to the invention, the fact that the game bodies are not found equally frequently in the individual intermediate recordings is therefore taken into account in that the game bodies are to be drawn from all intermediate recordings, as will be explained in more detail below.

REPLACEMENT LEAF Although other configurations also appear possible, according to the invention an embodiment with chambers arranged next to one another is considered to be particularly preferred, especially since adjacent chambers have a common axis of rotation and, of course ^, also a single drive, a common control etc. and can be formed integrally, whereby it is only necessary, for example in the case of a configuration of the mixing device in the manner of a drum, as is preferably provided, to separate the individual chambers from one another by means of radial partition walls. With such or a similar configuration (the

The outer wall obviously does not necessarily have to be cylindrical, but can be designed, for example, as a polygon, etc.) In the end, a single mixing device is then available for several or preferably all chambers, that is to say only one drive (motor and possibly transmission), one control Etc..

The different configuration of the Spielkδrper a group according to the invention preferably by a different size of the play elements (with the same material) realized with balls so by spheres of different diameter, wherein the body is sufficient for a ^'safe detection of the respective Spiel¬ when the difference of the through ¬ knife of the preferably spherical game body is relatively small (for example, is 20, 21 and 24 mm). On the other hand, however, ___ wj _____. «_ _ Balls are only relatively slightly different in diameter and are relatively difficult for players to recognize, so that a further feature according to the invention is that the different configurations of the game bodies of a group are at least apparent to realize the outside thereof by means of a different coloring, but this different coloring is not used for the device-based detection of the drawn game bodies, but only for the purpose of giving the players the possibility of immediately recognizing a drawn game result, in accordance with the above-mentioned instructions can. For example, the smallest ball of a game body in a group can be blue, the medium ball size yellow and the largest game body size black, so that the colors are at the same time a synonym for the specific size and vice versa and thus, together with the different sizes, are easy to identify of a drawn game result enables - for the device via the ball size and for the player via the ball coloring -.

The game body intermediate receptacles, which are an essential feature of the present invention, can be designed as webs adapted to the game body configuration in cross section, each of which is to be connected to a drawing receptacle of the chamber in question, in which case one between the intermediate receptacle and the drawing receptacle already mentioned above releasable lock is arranged, as described below in more detail.

To be able to do without any kompli¬ ed pulling means after release of the lock by means of which ^"is then eventually finally adopted by pulling the score concerned, serving as intermediate recording tracks for recording can draw

REPLACEMENT SHEET _ _t . be inclined so that in an embodiment of the game bodies as balls a non-locked ball then automatically runs into the drawing receptacle due to gravity, such an embodiment not only having the advantage of being easy to implement for the manufacturer, but also still gives the advantage of an excellent overview and transparency for the player. Of course, a game body return device is then also provided in such a design, which is assigned to a drawing receptacle, so that a drawn game body can be returned to the chamber after each game, such a game body return device also with a suitable design of the drawing receptacle and its Relative arrangement to the chamber in_: The easiest way to achieve this is to ensure that during a mixing process of the next game the drawn game bodies automatically return to the chamber due to gravity and are mixed there with the other game bodies of the group in question.

In a further embodiment of the present invention, a preferably automatic evaluation device can be assigned to each drawing receptacle, by means of which the type of the drawn game body can be automatically determined (and possibly registered).

A highly suitable embodiment of an evaluation device according to the invention has a drawing receptacle graduated in its clear passage cross section, the top end section of which is larger in cross section than the relevant dimensioning of all the game bodies

REPLACEMENT LEAF the group, and whose section immediately downstream of the uppermost end section is no longer permeable to a first type of game bodies and accommodates this type of game bodies, whose second section narrowed in the first passage cross-section follows the second section further narrowed for a second type of game bodies is no longer permeable and, as a result, a second type of game bodies is included in this section, etc., each section then being used for equipment

Evaluation of the game results can in each case be associated with a donor with whom it can be automatically ascertained whether or not a game body is present in the relevant section of the evaluation device or the drawing receptacle.

In total, only 21 different data are possible in the three types of game bodies which are preferably provided, three of which are determined in each game, but winnings are double (namely in the case of an offered opportunity: 2 or 4 x black ) can be realized up to 3,800 times the use. Whereas e.g. In the case of roulette-type gaming machines with 36 or 37 number of kettles, there are 36 or 37 input dates, but only winnings of up to 35 times the stake can be realized. In the case of the roller devices known as "one-armed bandits", on the other hand, gains in the amount of thousands of times the stake can be realized, but a large number of data must be processed for these bones in order to determine profits.

REPLACEMENT LEAF This above-mentioned very simple drawing process, to which the invention relates, could, of course, also be simulated electronically by using electronic random generators from, for example, six symbol groups of three different symbols, for example three different symbols, two of which are also identical to one another or the like. let choose.

Such an electronic design of the gaming device according to the invention would have other disadvantages (eg less tension for the player, because no process that can be observed and understood does not occur) above all the disadvantage that for the player the actual independence of the drawing from any legs ¬ Possibility of flow would not be recognizable, so that such a training must be regarded as a clearly worsened embodiment compared to the highly preferred completely mechanical training.

The releasable locks for the intermediate game body receptacles, by means of which the intermediate receptacles, with the exception of an intermediate intake during the final pulling process, are locked against a game body being released into the pulling intake assigned to the group, preferably consist of cams, fingers or the like ., which initially block the outlet side or dispensing point of the intermediate receptacles in question (so that the play body located in the unlocked intermediate receptacle can be supplied alone and insofar also safely to the drawing receptacle), and over it before completion During the drawing process, the game bodies initially held back fall back into the drawing and mixing chamber. These cams, fingers or the like. are mounted on a camshaft in a preferred embodiment.

REPLACEMENT _BL ATT The number of cams, fingers or the like. and the arrangement thereof on the Nockenwelle- "ind now ^made" so as _ß nach¬ on stepwise-rotation of the camshaft each one of the intermediate images is not locked, so that for example at from game to game success forming schritt¬ wise rotation of the camshaft in In the course of a series of games, all intermediate shots are not locked (or locked) with equal frequency, so that in the course of a series of games, all intermediate shots are drawn with the same frequency. According to the invention, the camshaft is rotated by 90, 180 or 270 degrees randomly.

Using an example, the following explains how the procedure according to the invention in principle affects the statistical frequency of the draws of the individual game balls;

After dicing, for example the average distribution of four different game balls, two of which are the same (A, B, C, C) over four positions (1, 2, 3, 4) from which they are to be drawn, converted to 100 draws the following:

33 16 24 27 = 100

29 22 18 31 = 100

C C 38 62 58 42 = 200.

If drawing results are now required which correspond to the probability values of 1/4 each for the game balls A and B and 1/2 for the game balls CC of the same design, these cannot be achieved with drawings from any particular position.

REPLACEMENT LEAF Only if all positions are drawn in an irregular order with equal frequency, are the results pure random results, as can be expected given the probability values of 1/4 and 1/4 and 1/2. In our example, the average numbers converted to 400 draws of this type would be:

For every 100 draws from items 1 2 3 4, the game balls A 33 + 16 + 24 + 27 = 100 and the game balls B 29 + 22 + 18 + 31 = 100 and the game balls CC 38 + 62 + 58 + 42 = 200 drawn.

In a preferred embodiment of this lock, all cams or the like can. on a camshaft or the like sit, which can be driven by a single drive, this drive preferably having a random generator which causes a random release of a game body held in the intermediate holder or the intermediate holders of a group.

Preferred embodiments of the present invention are described in the subclaims.

The invention is explained below using an exemplary embodiment with reference to a drawing. It shows:

REPLACEMENT LEAF It shows

Fig. 1 is a side view of the essential part of an embodiment of the gaming device according to the invention, namely the mixing device designed as a drum, which has several (namely six) chambers, each with four spherical, partially. differently designed game bodies as well as a pulling device for each chamber, the representation for the sake of clarity partly is schematic and fiction, non-essential parts are omitted;

Fig. 2 shows a section through the representation according to

^' - ^'"' - Fig. 1 seen in the direction of section line II-II, also in Fig. 1 after the end of a game or in the starting position for a new game; and

3 shows a representation corresponding to FIG. 2 after the first drawing phase, the game bodies each being located in an intermediate receptacle.

The drawing shows in a somewhat schematic representation, leaving out non-essential parts, such as the drive, a preferred embodiment of a gaming machine according to the invention with six essentially cylindrical (drawing) chambers 1. The chambers 1 are located in a cylindrical drum 2 made of transparent plastic, which can be reversibly rotated about its horizontally arranged longitudinal axis 3 by means of a drive (not shown). The chambers 1 are each delimited by an end wall 4 of the drum 2 and a radially extending intermediate wall 6 or by two intermediate walls 6, 6. In each chamber 1 there is a group of four spherical play bodies made of the same material, some of which are designed differently, namely in each chamber 1 there is a blue ball with a diameter of 20 mm hatched in the drawing, one in the Drawing shown in white yellow ball with a diameter of 21 mm and two black balls shown in black in the drawing with a diameter of 24 mm available. Since the slight size differences in the drawing are not recognizable due to the scale of the drawing, the balls 7 to 9 serving as game bodies appear essentially the same size in the drawing and are only somewhat exaggerated in diameter in the middle part of FIG. 1 shown large in order to better illustrate the function.

Fig. 1 shows the gaming device, and thus the drum 2 after the end of a game, and thus in the starting position for a new game, whereby it can be seen that there are three balls at the bottom of the respective chamber 1, while the fourth ball of each group is held in a drawing holder 11.

As can be seen in particular from FIG. 2, the drawing receptacle 11 of each chamber consists of a through hole provided in a radial flange 12, the diameter of which is slightly smaller than the diameter of the smallest ball

REPLACEMENT LEAF which in the present case is the (blue) ball 7 with a diameter of 20 mm ^' . If the diameter of the through hole forming the drawing receptacle 11 is therefore approximately .1.9 mm, then a ball 7 may be held by the drawing receptacle 11, but its lower portion still sinks through the flange 12 and protrudes over the underside of the flange 12 also.

If, on the other hand, a (yellow) ball 8, which has a diameter of 2 mm, is picked up by the drawing receptacle 11, the same thing basically happens, with the difference that a ball 8, due to its somewhat larger diameter, is only slightly less over the underside of the flange 12 extends out. The same applies to the inclusion of a (black ball 9, which has a diameter of 24 mm, whereby a ball 9 is also securely picked up by the drawing receptacle, but it is not absolutely necessary for this third variety of balls, that it goes downwards projects the flange 12, since this also leads to a corresponding display signal for the recording of a specific ball in the drawing receptacle 11 in the case of a mechanical tap.

In the region of the flange 12 there are inclined walls 13 directed towards the drawing receptacle 11, the lower end of which ends in each case in the flange 12 adjacent to the bore forming the drawing receptacle 11, so that a drawn ball is always fed to and from the drawing receptacle 11 concerned this is recorded.

Furthermore, each chamber 1 has one of the number of balls

- In the present case, therefore, four - corresponding number e of intermediate receptacles 14 for receiving one ball each after a mixing process. The intermediate 14 are

REPLACEMENT LEAF arranged at a distance from the drawing receptacles 11 (see in particular FIG. 2). They each fill the length of a chamber 1 measured in the longitudinal direction of the drum 2 and are designed in the form of grooves, so that after the mixing process each intermediate receptacle 14 is occupied by a ball.

Each intermediate receptacle 14 is provided with a slot 16 which extends through the casing of the drum 2 and which is a functional component of a lock designated as a whole by 17. The lock 17 has an axis 18 which is arranged on the outside of the drum 2 and extends over its entire length and has a square cross section, on each of which a pawl 19 is arranged on the axis 18 at the location of a slot 16. Each locking pawl 19 ^" has three locking fingers 21 _y arranged at right angles to one another, so that the locking pawls 19 are T-shaped in a side view from above and thus each locking finger 21 'is opposite a locking finger 21", while the locking finger 21'"therebetween has no locking finger The arrangement of the pawls 19 is such that adjacent pawls 19 of a chamber 1 are each rotated 90 relative to one another, so that three intermediate receptacles 14 are locked by a locking finger 21, while the fourth intermediate receptacle 2, all three locking fingers 21 ', 21 "and 21'" can be seen outside the drum 2, ie none of the locking fingers 21 protrude through the slot 16 into the drum, around the intermediate receptacle concerned 14 lock »while the other three intermediate shots 14 are each blocked by a locking finger 21 , as this is indicated in Fig. 3 with a dash-dotted line.

ERSA "rii ^ __. B'LA-TT The mode of operation of the gaming machine according to the invention is as follows:

At the start of a game, a player sets a certain game result and the mixing phase is then initiated from the starting position shown in FIGS. 1 and 2, the. Mixing device representing drum 2 is rotated in the direction of arrow 22 by a drive, not shown in the drawing, so that the balls still held in the drawing receptacles 11 from the previous game fall out of the drawing receptacles 11 and each of the three remaining ones move balls in the relevant chamber 1, with this mixing process in each chamber 1 the four balls 7, 8, 9, 9 being mixed together in the free play of the forces.

After the preferably reversing mixing, the drum 2 assumes a position as shown in FIG. 3, so that the balls which are mixed during the mixing process each arrive in an intermediate receptacle 14 in random order and thus in each chamber 1 in the four intermediate receptacles 14 lie side by side. If the lock 17 were not present, the four balls in each chamber 1 would now move in the direction of the drawing receptacle 11 of the relevant chamber when the drum 2 was rotated further in the direction of the arrow 22 about its longitudinal axis 3. First of all, it would not be ensured that a ball would be picked up with certainty by the drawing receptacle 11. Above all, however, it would not be possible to achieve the same number of pulls from each intermediate receptacle 14.

REPLACEMENT LEAF Each intermediate receptacle 14 is therefore assigned a T-shaped pawl 19, the arrangement being such that after the mixing process and before the actual pulling, three intermediate receptacles 14 are locked by a locking finger 21, while the pawl 19 of the remaining intermediate receptacle 14 is in a position in which no locking finger 21 engages through the slot 16 of the intermediate receptacle 14 in question in the latter, so that the ball located in this intermediate receptacle ( ^~ 14) is then rotated further

Drum 2, owing to its free mobility, is preferred to ^• the other balls of the relevant chamber 1 and reliably finds its way into the drawing receptacle 11 of the relevant chamber 1, while the locked balls ultimately reach the locking finger 21 in question in this further turning process the chamber 1 falls back, so that after the drawing process, when the drum is stopped in the position according to FIGS. 1- and 2, a state results in which in each drawing receptacle 11 of each chamber 1 one of the four balls is held while the remaining three balls have fallen back onto the bottom of chamber 1.

A mechanical determination or registration of the game result is possible by assigning a rocker arm 23 to each drawing receptacle 11 (the rocker arms are only shown in FIG. 1 in the first two chambers 1, but of course also in other chambers), which when a (blue) ball with the smallest diameter of 20 mm is picked up ^{, it} tilts the farthest downward from its raised starting position, whereas with a (yellow) ball 8, which has a slightly larger diameter, it tilts less accordingly and at a (black) ball 9 even less or not at all, depending on the design, so that the degree of adjustment of the rocker arm 23 in question is a signal for the type of ball contained in the respective drawing receptacle 11, and the rocker arm 23 with an electrical device (for example a light barrier or the like) cooperate, which forwards the signal in question to a registration device, not shown.

In the case of a new game, the lock 17 is either not adjusted by a drive 24 controlled by a random generator or is adjusted by one, two or three steps, so that after an adjustment which has generally been made, the next game in each chamber 1 will be different Intermediate holder 14 is not blocked, while the remaining three intermediate holders are each blocked by a blocking finger 21.

It can be seen that, despite its essentially purely mechanical design, the gaming device according to the invention is a 100% so-called random machine, and accordingly the gaming results are subject to the laws of chance without restriction. This is in itself already ensured by the mixing process itself, whereby, due to the lock 17, which blocks three of the four balls lying next to one another in a random arrangement during the drawing process and only blocks a randomly determined intermediate receptacle 14, it releases it, so that at successive games in a random order from the balls already randomly arranged after mixing from the outside or inside, especially clear for everyone, since this additional effect overlaps with the actual random process, so to speak, that somehow preferred drawing of a certain type of ball is excluded with 100% certainty.
