Abstract

The winning or loosing symbols are coupled to a winning scanner whose winning indicating signals are supplied to individual winning memories and indication elements. The memory and indication elements are formed into stepping switchgear, changeable by a random generator in the direction of higher or lower winning. The gambler has a possibility to store the indicated winning result in a credit counter. The winning values, associated with the memory and indicator elements of the stepping switchgear, form a geometric progression series. The winning scanner connected memory and indicator elements belong exclusively to continuous region of the series with low winning values. A control determines the gambling duration. It is activatable in dependence on the appearance of a winning result. The control starts the random generator until the winning value has exceeded an upper value, or fallen below a lower limit.

Description

Slot machine with revolving units carrying a profit symbol

The invention relates to a slot machine with winning symbols Circulating bodies that are put into circulation at the start of the game and that after they have been stopped show a combination of symbols that determines whether you win or lose are coupled to a profit sensing device, the profit signals of which are profit-specific Allocate memory and display elements that are assigned to a random number generator in Organized towards higher or lower profits changeable stepper are, whereby the player has the option of the saved and displayed profit to be re-stored on a credit counter for giving a profit.

In a patent application with the file number P 29 38 30701 is a Slot machine has been proposed in which the combinations of winning symbols (Profit line game) on disused circulating bodies, profit initially achieved in a profit-specific storage and display element of a stepping device is cached. The profit can either given immediately or for risk management in the stepping device with the help of a random generator can be increased or decreased.

The present invention is based on the object using technical means of the older registration to create a slot machine with which often small winnings are achievable, to give the risk-taker often an opportunity to risk the profit made in favor of a higher one. The task is achieved in that the memory and display elements of the step switching device associated profit levels a sequence with essentially geometric progression form that the memory and display elements which can be occupied by the profit sampling device exclusively to a contiguous area of the sequence with low profits belong, and that the playing time of the current game determining control device is provided, which can be activated depending on the occurrence of a win, wherein the control device starts the random number generator so often until the profit is an upper one Has exceeded the limit or has fallen below a lower limit, after which it will start the relocation the last achieved occupancy from the stepping device in the credit counter controls.

One scored in the payline game and one in the stepper cached as well as displayed Profit can be made at the request of the Player to be risked in favor of higher winnings, using the random number generator makes the decision about profit or loss. The possibility of risk disposition is given in the current game as often or as long as that of the stepping device reported profit level is within a lower and an upper profit limit. When the profit is re-stored in the credit counter, the stepping device emptied: the lower limit has been reached and the game is over. Considering In this framework, the playing time is otherwise not subject to any time limit.

The achievable in the payline game based on symbol combinations Profit is limited to the area of low profit. This is based on the legally prescribed payout rate of the slot machine has a high hit frequency guaranteed, so that the player often has the option of risk disposition Has.

The willingness to take risks is increased by making higher profits only are achievable in the risk game.

The win amounts assigned to the storage and indicator items form a sequence with an essentially geometric progression, i.e. that the next profit amount of the next element by multiplying it by a certain one Factor emerges from the previous one.

A sufficiently high chosen factor ensures that with few Steps are a big gain - the difference in height up and down can be overcome.

Advantageous further developments of the invention are set out in the subclaims refer to. A preferred embodiment of the invention is shown in the drawing and explained in the description below. They show: FIG. 1 front view of the slot machine according to the invention and FIG. 2 circuit diagram of the essential elements of the invention Parts of the slot machine shown in Fig. 1.

In the drawing in Fig. 1 is a total of 1 designated slot machine shown schematically with a front pane 2, behind which there are three dashed lines indicated roller-shaped circulating body 3 to 5 arranged coaxially next to one another are located. The circulating bodies 3 and 4 have rows of winning symbols on their circumference; they are put into circulation at the start of the game and show after they have been stopped each in a window 6 and 7 of the windshield 2 winning symbols, their combination decides on profit or loss.

The combination shown shows an eighty-pfennig payline, and according to the profit obtained, an indicator 8 lights up, the part a profit-indicating tape 9 composed of several display elements is. With the display element 8 also a credit key 10 lights up, when activity the profit with the extinction of the display element 8 in an indicating credit counter 11 arrives, the status of one at any time Payout of retrievable coin storage 11 'is increased by eighty pfennigs.

If the credit key 1û is not pressed, the recirculating unit decides 5, which is in circulation after the two left circulating bodies 3 and briefly come to a standstill is displaced, after its stoppage, whether the profit made eighty Penny is increased or decreased by an upward or downward one Arrow 12, which is visible in the window 13 of the front window 2.

It is believed that the arrow is pointing in the profitable direction points upwards, whereupon the display element 8 goes out and the next higher, 14, which indicates a profit of 1.60 DM, is illuminated. Simultaneously with that Display element 14 also lights up a risk button 15, and the right circulating body 5 starts up again. When a key is pressed, the recirculating body 5 decides again the increase or decrease in profit; if the risk button 15 is not pressed, so the profit of 1.60 DM is transferred to the coin store 11 'at the end of the game.

The risk-taking player comes with a further doubling of the profit in the area of special games, in which a winning key with increased profit expectations is granted, so that average per special game 1.60 DM won will. If the risk button 15 is not pressed after a win in the special game area then the last illuminated win is shown in the special game counter while the game is in progress 11 ″ of the credit counter 11 is transferred.

After pressing a third button 16, the player can score all Risking winnings again automatically without further intervention in the Game action needs. The third button 16 can be pressed again at any time be switched ineffective, whereby an assigned signal lamp goes out.

While the above description in external appearance and the use of the slot machine 1 was considered to be electrical below The mode of operation is described with reference to FIG. 2, where the same parts have the same reference numerals wear.

The rotating bodies 3 and 4 are provided with a profit scanner 17 coupled. Here, too, it is assumed that a monetary gain of eighty pfennigs was achieved.

The profit sampler 17 therefore switches a profit plus to the associated one Profit output 18 through, the one with an individual profit input 19 still to be described stepping device 20 is connected. This entrance is 19 at the same time set input S of a profit-specific memory element 21, so that the latter is occupied, with a signal at its output Q that is triggered by a profit individual Output 22 of stepping device 20 to activation input 23 of the display element 8 arrives, so that the profit achieved is visible there.

The switched through to the profit output 18 of the profit sampling device 17 Profit signal (profit plus) also comes through a summary of all profit signals OR gate 24 in a control device 25, where there is one hand in the activation input 26 of a random generator 27 and on the other hand in the clock input T of a D flip-flop 28 arrives, the output of which then sends an H signal into a control line 29. The activated random generator 27 generates at irregular times within of a specified time range at its with the clear input C of the D flip-flop 28 connected output 30 a reset pulse, which the D flip-flop 28 in its starting position resets so that its output signal falls to the L level. With the sloping HL-Flånke of the output signal a timer 31 is triggered, which after his characteristic time from its output 32 an H-pulse on the one hand in the clock input T of the D flip-flop 28 and on the other hand in the activation input 26 of the random generator 27 sends, so that the D flip-flop 29 is set again and the random number generator 27 is set again is started. This process is repeated as long as the input of the D flip-flop 28 an H signal from one of the storage elements, e.g. 22, of the stepping device 20 receives all but the memory element associated with the highest gain are combined in OR gates 33 to 35.

So if the win amount occupied in the stepping device 20 the lowest level (zero) or the highest level (sixty-four special games) has reached, the control device 25 is prevented, the SteuerLituwg 29 on Bring H level. To restart the control device 20, one is required Win sign-as from the win scanner 17 in a subsequent game.

The control line 29 is connected to a running release means (not shown) connected for the recirculating body 5 for the risk game; as long as there is an H signal on the Control line 29 is pending, the recirculating body 5 runs. After the end of the H-signal takes the recirculating body has a latching position in which it faces outwards An arrow pointing upwards or downwards, e.g. 12 or 36, is visible on the surface is, and a changeover contact 37 of a changeover switch 38 is either from its zero position placed in a profit-increasing or a profit-reducing position.

The changeover contact 37 receives indirectly from an occupied memory element a 14 signal, which in the case assumed here originates from the storage element 21, the by the OR gate 33 and the idle contact of the credit key 10 is directed. When the arrow 14 points upwards, the H signal enters a with + designated pulse input 39 of the stepping device 20 with the effect, that the occupancy of the memory element 21 to the next higher, not shown Storage element is transferred, so that then output 40 of the stepping device 20 is occupied and the display element 14 lights up.

When occupying the storage element for the profit 1.60 DM falls the output signal from the OR gate 33 at L level, so that the credit key 10 no signals influencing the profit situation can be passed.

A lamp 10 'assigned to the credit key 10, which shows the time indicates that the key has been activated, also no longer lights up, there is a lamp-controlling AND element 10 ″ by the L signal on its input 41 is prevented from switching through the H signal on the control line 29.

The outputs of the storage elements from 1.60 DM upwards - with the exception of the memory element for the highest win of sixty-four special games - are each connected to an input of the OR gate 34, the output of which with the changeover contact of the risk button 15 and an input 42 of one of these assigned Lamp 15 'controlling AND gate 15 "is connected, so that now the risk button 15 during the course of the revolving body 5, in which the other input 43 of the AND element 15 "receives the H signal from the control line 29, can be effectively operated.

In the following it is assumed that a key has been pressed effectively, in which a flip-flop 44 is set, the output of which has a persistent H signal the changeover contact 37 of the changeover switch 38 sets. Resetting the flip-flop 44 is done by the result signal output by the changeover switch 38, which is generated by an OR gate 45 reaches the reset input R of the flip-flop 44.

An AND element 46 belonging to the control device 25 and having an inverting one Input and a clock input that responds to falling HL edges is off Separate from the parts 26 described so far for reasons of clarity to 33 of the control device 25. The inverting input is with the The output of the flip-flop 44 and the clock input are connected to the control line 29. This ensures that the risk button 15 which has not been actuated has an L level Output of the flip-flop 44, the AND gate 46 is prepared, when it drops to the L level H signal of the control line 29 to generate a pulse at its output 47, the reaches the activation input 48 of an input circuit 49 whose inputs connected to the outputs of the storage elements for higher profits. The thus activated input circuit 49 writes the profit, which the occupied memory element the stepping device 20 is assigned to the credit counter 11 ″ and is generated then a reset signal, which is transmitted via a decoupling element 50 through the clear input L of the Stepping device 20 arrives at all reset inputs R of the storage elements.

It should be noted that the transfer of the low profits in the same Way through an input circuit 49 'in the credit counter 11', the Clear signal from the input circuit 49 'through a decoupling element 50' to the clear input L of the stepping device. 20 arrives.

If the rotating body 5 from the random number generator 27 at such a time is stopped at the one down pointing arrow 36 visible is, then the changeover contact 37 of the changeover switch 38 sets the stepping device 20 received occupancy signal to a connected to the stepping device 20 Loss line 51.

In the case shown in Fig. 2, the loss line 51 is with the Erase input L of the stepping device 20 connected, so that a complete Loss of profit made so far occurs. There is one in the risky situation Profit doubling compared to the profit loss with the same hit probability, so that the statistical payout rate of the slot machine exclusively from the Profit distribution in the payline game depends.

The loss line 51 can by folding over a solder bridge 52 with a Pulse input 53 of the stepping device 20 are connected so that at a If the loss is hit, the allocation is transferred to the storage element that is one step below the previously occupied one. If the previously used storage element the value ten pfennigs was assigned, then the profit is also if the value falls below completely lost here.

About the statistical payout percentage when downshifting gradually Leaving it unchanged is twice as many losing hits as winning hits over a long period of time to achieve. The number of arrows pointing downwards, e.g. 36, is therefore double as high as the one after above, e.g. 12.

The memory and the display elements forming the band 9 are win amounts assigned, which form a sequence with geometric progression; -the next higher Profit is obtained from the previous one by multiplying it by a factor p. While the previous description was based on a factor of p = 2, are also other values conceivable.

When the changeover switch 38, the stepping device 20 in each case can move one step forwards or backwards, with the profit level with the factor Multiplying p or dividing by p are used to maintain the payout percentage statistically indirect to make a profit decision p loss decisions.

If the occupancy level of the stepping device 20 at each Loss decision is reset to Nu-ll; are to maintain the payout percentage to make loss decisions on a winning decision (p-1).

After pressing a third button 15, a self-holding one closes Contact 55, which sends a continuous H signal on the one hand to changeover contact 37 of the Switch 38 and on the other hand to a lamp 54 'assigned to the button 54, so that the player automatically risks the winnings made without it further intervention in the game is required. The third key 54 can be deactivated at any time by pressing again, whereby the associated lamp 54 'goes out.
