BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a process for operating a coin-operated gaming machine of the roulette type, with a roulette-like number pan and setting keyboard arranged on the front side of the coin-operated gaming machine, in which the player fixes the amount of the stake by the insertion of coins and subsequent key selection, and a microprocessor then determines the game result by means of a random algorithm and, when a set number has been hit, activates the coin output unit for the ejection of the main win, and to a coin-operated gaming machine for carrying out the process.
In known coin-operated gaming machines of the relevant generic type, numbers from 0 to 12 can be set by means of one or more coins. Depending on the set number range and on the player's selection, in the event of a win an amount of up to 12 times the winning number can be paid out. It has been shown, however, that a maximum obtainable win multiplier of 12 gives players, who are aware of the possibility of achieving jackpot wins from other coin-operated gaming machines, only a slight incentive to play.
SUMMARY OF THE INVENTION
The object of the invention is to improve the process, mentioned in the introduction, for operating a coin-operated gaming machine of the roulette type, in such a way that, depending on chance, there is the possibility of achieving a maximum jackpot-like win. The object of the invention is, furthermore, to design a coin-operated gaming machine so that it allows the process to be carried out.
According to the invention, the solution for achieving this object is obtained in terms of the process by means of the defining features of claim 1 and in terms of the coin-operated gaming machine as disclosed herein. Advantageous embodiments of the invention are described in the dependent claims.
According to the invention, the player has the possibility that, in the event of a hit of the set number, the random-number generator of the additional processor determines a win multiplier for the maximum win which is a multiple higher than in known coin-operated gaming machines. In coin-operated gaming machines designed according to the invention, the factors of the random win multiplier are graded, for example, in the following divisions: 10, 25, 50, 100, 1000 or 8, 12, 20, 100, 1000. The statistical average of payouts actually made likewise amounts to 12, that is to say, even when the additional random-number generator is used, the statistical average remains at the win multiplier of 12. However, the random-number generator of the additional processor is so designed that in 85% of all game situations, when a set number is hit, the random-number generator determines only the lower win multiplier. Thus, if 15 stakes are placed on one number, in this case the player receives only ten times or eight times his stakes and therefore less than in the known coin-operated gaming machines. In contrast, in 15% of all game situations, when a set number is hit the random-number generator of the additional processor determines a higher win multiplier, such as, for example, 25, 50, 100, 1000 or 12, 10, 100, 1000. Thus, with 15 stakes on the hit number, a jackpot-like main win of fifteen thousand stakes is possible. This appreciably increases the player's incentive to play. Because the additional processor is designed as a 33-bit processor with a random-number generator, as a result of the large number of approximately 4.2 billion basic numbers it is virtually impossible to determine a random combination producing a jackpot. This affords the machine operator a good safeguard against unauthorized persons obtaining a jackpot by manipulation.
A risk circuit can also be provided additionally or alternatively. By the actuation of a risk key, the player can then, for example, play by risking the jackpot and thereby has the possibility of achieving a kind of superjackpot. It is advantageous, in this case, to display the "jackpot" status on the front face of the coin-operated gaming machine, so that the player still has the o
