Slot machine

The invention relates to a gaming machine with symbols-carrying, movable drums or the like, which convey a new, random symbol display with each game, one with the drums or the like cooperating gain decoding unit »which at each emits a win signal from several possible win symbol displays, and one controlled by the decoding unit, a corresponding profit-releasing profit ejection unit are provided for each profit symbol display.

In such slot machines, one of many possible combinations of symbols is displayed for each game, which is not predictable, but occurs randomly. Certain combinations of symbols displayed is assigned a profit. Is such a winning symbol in a game display is achieved, then the machine throws the corresponding one Profit from.

In most of the known slot machines of this type, the win symbol displays are those associated with a win symbol combinations displayed, and the corresponding

ch.end.en winnings predetermined and fixed, the player can so only operate the machine to change the display. He is therefore not actively involved in the game, what the Interest in gambling hurts.

The object of the invention is to create a gaming machine of the type specified at the outset, which is an active one Enables the player to participate in the game, so that the game becomes more interesting. The player has the option of to increase his winnings by correctly predicting the symbol display achieved on his next game.

The slot machine according to the invention is therefore marked by a preselecting element for preselection that can be operated by the player before actuating the drums or the like some of the win symbol displays and / or the winnings for at least some of the win symbol displays.

In one embodiment, profit symbol displays can be used which will either be added to a standard set of win symbol displays or which will be selected beforehand selected or a standard set of win symbol displays substitute. In another embodiment, the prizes can be preselected in such a way that the prize one or more special win symbol displays upon achievement the same is increased in each case. In a further embodiment it is possible to have both the winning symbol displays as well as selecting the winnings.

In all of these slot machines, the preselection is made in that the player selects one of the symbols and registers this selection so that the slot machine throws out a corresponding win if there is a subsequent game

a specific symbol combination or one of several specific symbol combinations in the Atizeige, which contains the registered symbol.

With the pre-selection option in the slot machine according to the invention, the player can increase his winnings by that he displays the following symbols, i.e. displayed symbol combination, correctly predicts. This increases the interest in the game, as mentioned.

Advantageous embodiments of the invention can be found in the attached claims 2 to 11.

An embodiment of the invention is described below with reference to the accompanying drawings, for example. They show, each as a schematic circuit diagram:

Fig. 1 the essential components and the control unit of a gaming machine according to the invention}

Fig. 2 shows part of the win decoding unit of the gaming machine according to Fig. 1 $ and

Fig. 5 shows the winning ejection unit of the gaming machine according to Fig. 1.

The slot machine has three drums BI, E2 and Ή.3 , which are provided with symbols on the circumference, arranged coaxially to one another and driven by a motor M, as usual. An electronic control unit is provided which has a timer pulse generator E and a binary counter F which counts pulses coming from the generator E

309829/0238

and when the count is 28, 40, 52 and 60 control pulses NAND gates G1, G2, GJ and G4. These effect via bistable circuits Hl, H1; Ή "2, H2j Ej, HJj H4, H4 a control of electromagnetically operated brakes S1, S2, S3 and an electronic switch S4, which the drums BI, E2, B3 and the motor M are assigned.

If the slot machine is switched on but not in operation, then a comes from the output of the conductive part HJ the bistable circuit TTj, HJ derived locking signal the conductive parts C and D of the bistable circuits ü, C and TJ, D of the binary counter F, so that these bistable circuits TT, C and U, D are kept in the zero state, and the Counting range of counter F is limited to 16. As long as the gaming machine is switched on, the timer pulse generator also works E. If the machine is not in operation, i.e. if it is not used, then the binary counter F counts continuously up to 15 * to then switch back to zero, what the Count 16 equals. In the meantime, none of the NAND gates GH to G4 can pass a control pulse, since this is only can happen when the counter F has reached the count 28, 40, 52 or 60, which cannot occur due to the limitation of the counting range up to 16.

The timer pulse generator E has two Schmitt's Trigger El and E2 with a common input. The two outputs are each connected to the input of a NAND gate EJ connected, as can be seen from FIG. The two triggers El "and E2 oscillate at different frequencies and cause that from the NAND gate EJ a pulse signal goes away, which consists of a train of pulses with irregular interval on. This pulse signal arrives at the input of the Binary counter F.

309829/0238

__ This has six bistable circuits P, Pj Q, Qj A, A; B, B; C, G and D, D connected to one another in the manner shown in FIG. The two parts P and P or Q ₁ and Q or A and A or B and B or C and C or D and D of each bistable circuit represent the two alternately conductive parts or stable states. The generator ü is connected to the first bistable circuit P, P, the conductive parts A, A} B, Bj C, C and D, D are connected on the output side to the inputs of six .NAND gates G1, G2, G3, G4, G5 and G8 which each have four inputs. These connections are not shown in detail in FIG. 1, but are only indicated by specifying the corresponding reference letters for the conductive parts at the inputs of each gate. The connections are such that the gates G1, G2, G3 and G4 each deliver an output signal when the counter E ^{1 has reached} the count 28 or 4-0 or 52 or 60. The highest possible count is 64-, the output signals control the brakes S1, S2, S3 and the switch S4- via the bistable circuits H1, H1j H2, H2j H3, H3 and H4, H4-.

The operation of the slot machine is mechanism by inserting a coin into a coin slot, not shown started. As a result, a switch T is actuated, which in turn via the NAND gate GJ? the bistable circuit H4-, H4- switches to such a state that the engine M starts, and that a shift register J switches back. The shift register J works with a number of selector switches El to K5 as a pre-selector to be described in detail, which when one of the switches ΚΊ to KJ? via a bistable Circuit H5, H5 the bistable circuits HI, H1j H2, H2 and H3, H3 switches into such states that all three drums El, E2 and R3 are released, and that at the same time the locking

309829/0238

signal at the counter F disappears, so all drums Rl, R2 and R3 can circulate regardless of the count of counter F.

When the count is 28, the NAND gate G1 supplies one Control pulse which the bistable circuit H1, H1 in such a state switches that the brake S1 stops the drum RI. The NAND gates deliver in the same way G2, G3 and G4 later when the count is 4-0 or 52 or 60 Control pulses that are transmitted via the respective bistable circuit and brake or switch S4 · the drums R2 and R3 or the motor M shut down, the counter F finally automatically switching back to zero at the counter reading 64. The actuation of the control unit to stop the motor M also triggers a win decoding unit via a connection Z4 and a win ejection unit via a connection Y2. Then the gain decoding unit speaks to the end position of the drums RI, R2 and R3 and supplies information about the corresponding win to the win ejecting unit, which coins accordingly throws the profit.

Each drum RI or R2 or R3 runs for as long as the counter F needs to count from the initial count at the start of all drums to the count at which each drum is stopped. The initial count can be anywhere within the limited range from zero to 16, and only for this reason does the rotation time of each drum R1 or R2 or 3 generally vary from game to game of the gaming machine. In the embodiment shown, the unpredictable, random fluctuation in the rotation time of the drums due to the different output counts is of the order of + 8/20

309829/0238

- ^r ? -

or + 30% »based on the rotation time of the drum RI, if the counter F counts regularly. However, the latter is not the Case, because of the temporal irregularities of the pulses from generator E. Therefore, the duration changes which counter F needs to count any particular count range, and thus the randomness becomes the Circulation duration of each drum El or R2 or R3 continues to increase.

In the above, the sequence of operations in the control unit is described, whereby the circulation of the drums RI, R2 and R3 as well as the operation of the gain decoder unit and the prize ejection unit can be controlled.

In the slot machine shown, the pre-selection element is essential, which is from the five-stage slide register J and the five selector switches K1 to K5. Each level J1 or J2 or J3 or J4 or J5 of shift register J. connected on the input side to another of the switches K1 to K5 and becomes conductive when the associated switch Ki or K2 or K.3 or K4- or K5 is actuated. Furthermore, everyone is Stage J1 to J5 on the output side via a diode L to the input a reversing gate G7, furthermore connected to the thread decoding unit via a connection X1 or 22 or X3 or Σ4- or 25.

As already mentioned, the switch is activated by inserting a coin into a coin insertion mechanism, not shown T closed so that the NAND gate G ^ the shift register J supplies a signal which switches all stages J1 to J5 back to the non-conductive state. The player then only has to select one of the selector switches K1 to K5 and

309829/0238

operate so that the corresponding stage of the shift register J is triggered "and the reversing gate G7 a position output signal supplies. The gate G7 then supplies the shift register J with a zero signal which prevents that actuation of another selector switch energizes one stage of the J register. It also delivers a similar signal the bistable circuit H ^, H ^ so that the three drums RI, E2 and R3 as well as the counter F are enabled.

The said actuation of one of the selector switches K1 to K5 also has an output signal to the win decoding unit via the corresponding connection X1 or X2 or XJ or X4 or X5. Isn't that even further down This is the only such signal and it represents a corresponding winning combination in the gain decoding unit. Each selector switch K1 to K5 is preferably on the associated pushbutton with a different symbol. The ones in the gain decoding unit Winning combinations set by pressing the push button contain this symbol. For example, assume that the switch K1 is assigned a plum as a symbol, and that the actuation of this switch the setting of winning combinations in the winning decoding unit, which results in a plum on the drum R1 alone, Include plums on drums R1 and R2 alone, and plums on all three drums RI through R3.

The logic gate circuit according to FIG. 2 represents that part of the winning decoding unit which is based on winning combinations with a plum symbol, which combinations as a result of a signal in the connection X1 as a result an actuation of the switch K1 have been set. Information about the rotary position of the drums RI bis

309829/0238

R3 are supplied via connections Z1, Z2 and Z 3, and from position providers. These consist of sliding contacts W1, W2 and W3, which are connected to the drum R1 and R2 or R3 are rotatably connected and with electrical pins cooperate on pin plates V1 or V2 or V3. Every Pin plate has two pins for each rotational position of the associated Drum on, the pins are arranged so that in a rotary position the corresponding pin pair from associated sliding contact is connected and supplies a positive output signal in a connected connection, which shows the respective rotary position of the drum. The connections Z1, Z2 and ZJ are each to the pin pairs Pin plates V1 or V2 or V3 connected, which together are connected and provide positive output signals when the associated drum Ei or R2 or E3 is in is in a rotary position in which the symbol of a plum is visible.

The connections Z1, Z2, Z3 and X1 are all according to Fig. 2 with four NAND gates G11, G12, G13 and G14- on the input side connected, each of which is assigned a NAND gate G21 or G22 or G23 or G24 with two inputs. Output side the NAND gates G21 to G24- each have a connection 2 or 4 or 12 or 8 are connected to the prize ejection unit. To the second input of each of the NAND gates G21 to G24 is the connection Z4 via a reverse gate G20 connected.

The connections XI and ΊΑ supply control signals to the two groups of NAND gates G11 to GI3 and G21 to G24. The control signal in connection X1 depends on the selector switch K1 and is a zero signal which blocks gates G11, G12 and G13, if switch ΚΛ is not actuated,

309829/0238

however, it is a positive signal which enables these three gates to be actuated when switch K1 is actuated has been. The control signal in connection Z4 depends on the Motor M off and is a zero signal which blocks the gates G21 to G24 when the motor M is in operation, however a positive signal which enables these gates to be actuated when the motor M has stopped. The following is the mode of operation of the circuit according to FIG. 2 explains when the selector switch E1 has been actuated and the motor M is at a standstill, with all three drums RI to R3 one of the three winning combinations with plum symbols pointing.

Only the first drum RI is in one such rotary position, in which it shows the symbol of a plum, then goes to the NAND gate via the connection Z1 G11 a positive signal so that the gate sends a zero signal to one of the inputs of a NOR gate G15 with two inputs supplies. The other input of the NOR gate GI5 is a zero signal via an inverting gate G16 from the output of the NAND gate G12 abandoned, so that the NOR gate GI5 a positive Signal supplies one input of the NAND gate G21 with two inputs, for which this a zero signal via the connection 2 supplies to the prize ejection unit.

Are only the first two drums RI and R2 in such rotary positions in which they have plum symbols show, then positive signals are given to the NAND gate G12 via the connections Z1 and Z2, so that there is a Zero signal supplies the input of the reversing gate G16 and one input of a NOR gate GI7 with two inputs. That Reverse gate G16 supplies a positive signal to an input of the NOR gate GI5, which signal acts as a blocking signal and prevents the gate from sending a positive signal to the NAND gate

309829/0238

ter G21 supplies to the ejection unit via the link 2 to switch. The NOR gate G70 is the NOR gate GI5 similarly, and its other input is a zero signal via an inverting gate G18 from the output of the NAND gate GI3 abandoned so that it is based on the zero signal from NAND gate G12 responds and a positive signal supplies one input of the NAND gate s G22 with two inputs and this a zero signal the ejection unit gives up via connection 4.

If all three drums RI to R3 are in rotary positions, in which they show plum symbols, positive signals are given to dem via the connections Z1, Z2 and ZJ NAND gate GI3 supplied, so that this is a zero signal The input of the reverse gate G18 supplies, which supplies a positive signal. This is applied to the NOR gate GI7 and acts as a blocking signal to prevent this gate from giving a positive signal to the NAND gate G22 to switch the prize ejection unit via connection 4. A similar blocking signal is also sent via the reversing gate G16 abandoned the NOR gate GI5, as mentioned, which prevents that the profit ejection unit is switched via connection 2 will. The positive signal from the reversing gate G18 also reaches one input of the NOR gate GI9 with two inputs, which is between the NAND gate G14 and a NAND gate G24 lies. It acts as a blocking signal, which prevents the positive signal from NAND gate G14 to the NAND gate G24 reached. Eventually, the same positive signal from inverting gate G18 also becomes an input of a NAND gate G2J abandoned with two inputs, so that this supplies a zero signal of the profit ejection unit via connection 12.

Is a switch other than switch K1 actuated, and is a combination of three plum symbols is shown when the drums R1 to R3 and the motor M stand still, then prevented

309829/0238

the locking signal, which is sent to the NAND gate G13 via the connection Σ1 lies in the fact that it emits a zero pulse for switching the profit ejection unit. However, this locking signal controls not the NAND gate G14-, whose inputs are connected to the connections Z1, Z2 and Z3 are connected so that this supplies a zero signal to the NOR gate G19. At the other entrance of the gate GI9 is no longer a blocking signal from Gate G18, so that it gives a positive signal to the NAND gate G24, which is thus via the connection 8 of the profit ejection unit supplies a zero signal.

The part of the win decoding unit shown in Fig. 2 responds to winning combinations which include one, two and three plum symbols, the control being such that when the selector switch K1 with plum symbol is not actuated, it only responds to the combination with three plums responds and a corresponding signal via the connection 8 of the profit ejection unit gives up, while when the switch K1 is operated it responds to the combinations with one, two and three plum symbols and each delivers a corresponding signal to the profit ejection unit, via the connection 2 or . 4 and 12. the numbering 2, 4, 12 and 8 unit for the compounds to gain ejection indicates the number of coins, which ejects the ejection unit gain when a signal is fed via the appropriate connection. The actuation of the selector switch K1 thus serves to increase the profit according to the three winning plum combinations. This also adds two new winning combinations, each of which is assigned a correspondingly lower win.

The entire gain decoding unit has logic gate circuits similar to that of FIG. 2 for each of the switches

309829/0238

K1 to K5. A different symbol is assigned to each selector switch, and the connections corresponding to connections Z1, Z2 and Z3 are corresponding to the drum position transmitter connected. The gain decoding unit can also have other logical ones Have gates that convey other winning combinations that are always set, independently of which of the switches K1 to K5 has been operated. Such winning combinations may contain symbols which are not assigned to switches K1 to £ 5. The these Combinations of prizes allocated to each are simply determined and can be determined by the connection to the prize ejection unit can be selected as desired.

The profit ejection unit can be designed in any way, provided that it is only guaranteed that it is triggered optionally or can be triggered to eject any number of coins. Preferably, however, the prize ejection unit has one Digital counter on which of the signals supplied by the gain decoding unit is in a certain state is switched and then counts from this state to the maximum capacity, with each counting step taking place a coin is given.

For example, such a prize ejection unit can be constructed in accordance with FIG. 3. In this case, a coin ejection mechanism with drive motor N is provided, controlled by a binary counter E ^{1 in} such a way that the number of coins is ejected which corresponds to the winnings, which are each indicated by a Hullsignal, which via a connection 2 or 4 or 6 or 8 or 10 or 12 comes from the thread decoding unit. The binary counter E ¹ has four bistable circuits I, Aj ΊΪ, Bj ü, C and I), D, which are connected in such a way that a counter with a counting capacity of 16

309829/0238

results. Each of the conductive parts A, B, C and D is biased on the output side with a voltage of 5 ^{volts, which normally keeps the counter E 1} in the zero or 16-count state. All these connections on the output side are connected by one or more of the diodes L ¹ to the connections 2, 4, 6, 8, 10, 12 and 5, as can be seen from FIG the 14 or 12 or 10 or 8 or 6 or 4 or 11 count status triggers or switches.

Each of the conductive parts A, B, C and D is connected on the output side to an input of a NAND gate G25 with four inputs, in such a way that positive output signals are only delivered simultaneously when the counter E ¹ is at zero or 16 -Counting state is, whereupon the NAND gate G25 applied to the input of a NAND gate G26 with two inputs with a zero signal. If the counter E ^{1 has been switched} to any other counting state than 16, namely by a zero signal in one of the connections 2, 4, 6, 8, 10, 12 and 5, then the NAND gate G25 supplies the input of the NAND Gate G26 a positive signal. The other input of the NAND gate G26 is connected to the connection Y2 from the control unit (FIG. 1), which only supplies a positive signal when the motor M is at a standstill. If the ^{counter E 1 is} in a counting state other than zero or 16, and the motor M is still at a standstill, then the NAND gate G26 supplies a zero signal which is reversed by a reversing gate G27 and the motor N starts. This then causes the coin ejection mechanism to eject coins one after the other and actuates a switch T ¹ so that a bistable circuit H7, H7 emits a pulse each time a coin is ejected, which pulses are applied to the binary counter E ^{1 on the} input side and cause

309829/0238

that this counts up to the zero or 16 count state. If the counter E ^{1 reaches} the zero or 16 count state, then four positive signals are fed to the NAND gate G25, which then outputs a zero signal to the NAND gate G26, so that the motor N is stopped and no more coins are ejected.

If a zero signal is sent to connection 2 by the winning decoding unit, then the counter E ¹ switches to counting state 14-, the motor N starts, and the coin ejection mechanism ejects two coins before the corresponding pulses from the bistable circuit H7, H7 cause that the counter E ¹ counts up again to the counting state zero or 16, in which it stops the motor N. Likewise, ^{when there is a zero signal in connection 4-, counter E 1} switches to counting state 12, so that four coins are ejected before counter E ¹ returns to counting state zero or 16 and motor N comes to a standstill. Zero signals in connections 6, 8, 10 and 12 cause 6 or 8 or 10 or 12 coins to be ejected in the same way. In the logic gate circuit of the gain decoding unit according to FIG. 2, connections 2, 4, 8 and 12 are provided, but these connections can be changed in such a way that a different gain is assigned to one, two or three plums.

The connection 5 of the profit ejection unit is not connected to the win decoding unit, but rather to a change mechanism which, when a 10-Neupfennig coin is inserted causes a zero signal in connection 5, so that the coin ejection mechanism two Neupfennig coins gives away.

It has already been mentioned above that the actuation of a selector switch K1 to K5, the output of a signal to the

309829/0238

Win decoding unit via the corresponding connection X1 or X2 or X3 or Σ4- or 1 $ has the consequence, which is the only such signal, if a special state is not given. The preselector is designed so that it ensures this special, profit-increasing condition. All winning combinations are set at the same time in accordance with the selector switches K1 to K5 if certain conditions are present. This happens when a selector switch K1 or K2 or KJ or K4 or K5 is operated when the counter F of the control unit is in counting state 15, which state is determined by the coincidence of two pulses, namely a pulse from a NAND gate G8 with four inputs, which is connected to the counter F and delivers a zero pulse when the counting state 15 is reached, and a pulse from the reversing gate G7, which delivers a mulled pulse when one of the switches K1 to K5 is operated. The pulse from the NAND gate G8 is applied to one input of a NAND gate G1O with two inputs via a reversing gate G9, while the pulse from the reversing gate G7 is fed to the other input of the NAND gate G1O via an AC-coupled Schmitt's trigger E4.

The counter F is in the counting state 15 when actuated one of the selector switches K1 to K5, then become positive Signals given to the two inputs of the NAND gate G1O, which a bistable circuit H6, H6 supplies a zero signal so that it switches and a positive signal supplies the series input of the shift register J, and also an input of the NAND gate G11 with two inputs. The other The input of the gate G11 is connected to the output of the timer pulse generator E connected so that the positive signal from the bistable circuit H6, H6 causes the gate G11 supplies pulses that correspond to the generator's timer pulses

309829/0238

E correspond to the shift register J, so that all stages J1 through J5 of register J are energized. All connections X to X ^ are thus supplied with signals, to set the corresponding winning combinations in the winning decoding unit. The bistable circuit H6, H6 is then switched back, namely through a signal from the output of the gate GI at the count state 28. The shift register J is switched back by a pulse from NAND gate G5 when the next player receives a coin interjects.

In the control unit according to FIG. 1, the counting range of the binary counter F is restricted before a coin is inserted, namely by means of a reverse voltage which is applied to the last two bistable circuits C, G and D, D of the counter F. In another embodiment of the invention, a logic gate between the bistable circuits B, B and (T, C be switched on, which is controlled by a signal corresponding to the lock signal so that no pulse is passed between these bistable circuits before not a coin has been inserted.

In another embodiment of the invention, the control unit can have a timer pulse generator, which supplies pulses at irregular intervals, furthermore a digital counter to which these pulses are given, whereby the application of these pulses to the counter is interrupted when the slot machine is not in operation, i.e. is not played, but the said pulses to the counter arrive when the slot machine is in operation, so that the counter counts irregularly from zero, i.e. at irregular speed, according to the interval between successive impulses, whereby the counter

309829/0238

the following signals for controlling operating processes in the slot machine with predetermined counting states above zero gives away.

The control unit can be used not only in gaming machines of the type described, but also generally in sol chen slot machines, which have a predetermined sequence of control pulses to control a series of operations in random require chronological succession after the start.

Although the preselection or the preselection element is primarily essential to the invention, the control unit, the gain decoding unit with logic gate circuits to which electrical signals are applied, which indicate the positions of the drums and which provide corresponding signals indicating the profit achieved, and the profit ejection unit with a counter that counts up to its maximum capacity, with each counting process a coin is ejected, always inventive.
