DE2928643A1 - Coin-operated gaming unit - feeds win signals to computer connected to up=down counter and to game blocking unit - Google Patents

Abstract

Control of pay-out for a win in the coin-operated gaming unit is ensured by a computer which receives the pulses of successful game. The computer follows an algorithm deriving a given tolerance for the win pulses and is connected to an up- down counter and pulse separator. The two-state unit of the computer is switched by zero-crossing of the counter, and when the tolerance is exceeded an activation signal is generated. The pulse separator is set to the specific statistical pay-out value of the gaming unit while the zero crossing in the counter provides a signal for the AND gate which sets the output of the pulse separator feeding a flip-flop.

Description

Slot machine

The invention relates to a slot machine with a game mechanism, coupled to the generation of profit pulses g with a profit sensing device is, with a game flow control, a random number generator and a game lock contains and which, for the start of the game, emits game insert impulses to the game mechanism, with a predetermined statistical numerical ratio between winning impulses and game stake impulses consists.

In slot machines it occasionally happens that due to a Defective too much or too little profit is paid out, whereby the defect often occurs a manipulatory intervention is due. Accordingly, the invention resides the underlying task of designing a slot machine of the type mentioned at the outset in such a way that that the winnings are paid out in an orderly manner.

The object is achieved in that a computing device is provided which receives the winning impulses and the stake impulses at its inputs, that the computing device executes an algorithm T = g - q.e, with a tolerance determined | and that an output of the computing device is connected to the game lock is that when the tolerance is exceeded over a predetermined amount, an activation signal leads. This creates a self-control for the slot machine; he is no longer playable when its payout - measured; at its given Payout percentage - up or down above a predetermined tolerable amount deviates.

A particularly advantageous embodiment is that the Computing unit contains a two-state organ, the state of which addicted changes from the zero crossing of the counter and that at least one output of the two-state organ is associated with an ad. This means that it can be determined retrospectively whether little or too much was paid out.

The invention is illustrated below with reference to one in the drawing Embodiment described in more detail.

In the drawing, the only figure shows the invention for understanding ded necessary elements of a designated 1 slot machine.

A game sequence control 2, which contains a random number generator 3, generates a game stake signal at the start of the game, whereupon a game mechanism 4, with a win scanner 5 is coupled, is started to at the end of the game shut down the play mechanism 4 with the aid of the random generator 3 and the To activate profit sensing device 5.

The following description assumes that the first two games are profitable and that in the third game a win of 10 times of the stake is achieved.

The game stake signals e reach the input 6 of a computing device 7, which is also the input of a pulse divider 8.

The pulse divider 8 is set to such a division ratio q, which corresponds to the machine-specific statistical payout rate, q, where the Payout ratio q, which is 2/3 here, is the ratio of win to stake.

After the third stake impulse occurs, the impulse divider generates 8 a double pulse which is fed to a counter 10 via a changeover switch 9 should, assuming that its status is zero. The zero tap of the Counter 10 is connected to the input of an AND element 11, so that this prepares it is, the pending pulse at the output 12 of the pulse divider 8 to the set input S of a flip-flop 13 to be switched through, whereupon its output is activated, see above that the switch 9, its control device 14 with the output tied together is switched. The double pulse now reaches the one marked + Counting input of the counter 10 and increases its value by two, with only the output 2 is energized With the outputs Q and Q of the flip-flop 13 there is also a sign display 15 and 16 connected as a supplement to the counter information according to the amount.

At the end of the third game run from the win scanner 5 ten profit pulses g via the switch 9 into the counter 10, the first of which two pulses enter the counter input marked with - and thus the counter reading bring from two to zero. The zero tap of counter 10, which is now energized, is also connected to the input of an AND gate 17, so that this prepares is to switch the following win pulse through to the reset input R of the flip-flop 13, whereupon its output is energized and its output is de-energized, so that the switch 9 due to its signal free position + input 14 into its rest position falls. The remaining eight winning impulses now run through the one marked + Count input into counter 10 and increase its status accordingly.

Over the course of a large number of games, the meter reading will become more frequent Be zero, provided that the number g of winning impulses corresponds to the number e of stake impulses remain in the long term in the ratio q to which the pulse divider 8 is set is.

In the following it is assumed that a defect in the Game sequence control 2 too few or too many winnings are played out. This mistake, which can occur, for example, when the random number generator has 3 preferred positions occupies, is; not immediately detectable; one needs to determine it Control run, which may have to be extended over several thousand simulated games.

The error causes the reading of the n-stage counter 10 to be continuous grows and initially reaches the 0.7 n-th stage.

The counter output corresponding to this level is marked with one of Outside visible signal lamp 18 connected. In the event of a persistent over the following games A technical check of machine 1 is recommended.

In the case of the assumed error, the counter 10 will ultimately be its own! Final score reach, with a signal appearing at its nth output. The nth output is connected via an OR gate 19 to the control input 20 of a switch 21, see above that the toy factory 4 is permanently blocked.

Another input of the OR gate 19 is not shown with one Impact protection contact connected; the switch 21 is customary in the industry as a foul relay designated. -i The computing device 7 according to the invention can advantageously also be used for Determination of other statistical data can be used.

Another example is a game provided with rotating bodies Werk 4 called, which brings the winning symbol to the predetermined locking positions. The pulse divider 8 set to a numerical ratio q equal to the number of detent positions. Position signals take the place of profit signals.

A final example is given for a slot machine with Opportunity to win a special game. In the case of special games, a winning key comes with a specified increased chance of winning to apply. The counter reading can be from the number of games in one direction and the number of special games in the other direction will.

The collection of statistical data is simplified in computer-controlled Machine and always guarantees intrinsic safety.
