A group of associated gaming devices each having a lottery drawer 25 including a memory for storing a database 18 having a plurality of entries each containing one or more winning numbers associated with a predetermined time interval, a pseudorandom number generator 20 for generating numbers from a seed supplied by the database 18, a clock 19 for extracting the winning number or numbers from an entry of the database 18 for the time interval indicated by the clock 19, a comparator 22 for at least one receiving of the extracted winning number or numbers and at least one number generated by the pseudo random generator 20. The comparator 22 is adapted for generating a win signal when the winning number and the generated number match. All of the associated gaming devices include identical databases and pseudo random number generators whereby win signals are generated simultaneously. The header of the database entry may include the seed for the pseudorandom generator. Eligibility for the lottery draw may be determined. The invention allows a group of gaming machines to award a group event at the same time without requiring a wired or wireless network between the machines. |
