Patent ID: 7037193

Claim:
A method for playing a lottery game, comprising: providing a computer connected to a precision timer; providing a portable memory device to a lottery game participant, said portable memory device being connectable to the computer, the portable memory device including at least a microprocessor, and a timer unit, a memory, and an input-output device, each interconnected with the microprocessor; providing a time characteristics measuring device connectable to the timer unit of the portable memory device; connecting the portable memory device to the computer; by means of the time characteristics measuring device, measuring at least one of a frequency f and a period t of data N outputted from the timer unit, and recording a data of the measured frequency f or period t into the computer, wherein N is a number; by means of the computer, reading off and storing data T 1 outputted from the precision timer, wherein T 1 is a time value; by means of the computer, reading off and storing data N 1 outputted from the timer unit at a moment when the data T 1 are outputted from the precision timer, wherein N 1 is a number; disconnecting the portable memory device from the computer; providing the lottery game participant with access to the at least one portable memory device and allowing the lottery game participant to play the lottery game, during which true information regarding the lottery game and a corresponding time are registered; by means of the input-output device, receiving an i-th proposed information associated with the lottery game, which is inputted by the lottery game participant, and by means of the microprocessor, recording the i-th proposed information together with corresponding data N(i) into the memory, wherein i is an integer, N(i) is a number, and the data N(i) are outputted from the timer unit when the i-th proposed information is entered; reconnecting the portable memory device to the computer and reading off the recorded i-th proposed information and corresponding data N(i); comparing the i-th proposed information with the true information, and if a result of the comparing is within a required coincidence level, calculating in the computer a time T(i) of recording the i-th information by a formula: T(i)=T 1 +[N(i)−N 1 ]*P, wherein P=1/f or P=t; and determining a prize for the lottery game participant based on the calculated time T(i).
