<p>The present invention discloses a method for drawing lots and calculation of a possible prize in an electronic lottery in a central server. In a storage device of the server, a number of counters are stored, used to determine if wins occur for lottery ticket requests. The requests are queued and executed in the same order as they arrived the server. The counters are incremented for each request, and each counter is then compared with a respective winning number. A win occurs when a counter is equal to its associated winning number, and the winning value is proportional to the winning number of that counter, wherein the proportional ratio is a constant stored in said storage device. The winning number may be constant, or may be calculated again each time the counter reaches its associated winning number. The winning value may also be constant, or vary in a corresponding way. At each winning occurrence, the respective counter is reset to an initial value, or the respective winning counter is set to a value larger than the respective counter. The method may, e.g., be used in an electronic lottery where the lottery tickets are ordered from a cellular phone, e.g. by transmitting a short message to a certain telephone number.</p> |
