The inventive method for carrying out a lottery relates to methods for carrying out game processes with a participation of owners of identification cards. Said method consists in issuing lottery tickets, forming data on participants, distributing a lottery fund, carrying out a lottery and paying-off. The lottery is carried out using identification cards and the lottery tickets are issued in e-form. For this purpose, an identification data set on the e-form lottery tickets used for a payoff distribution is formed in a lottery part. The data on said tickets is included in the set of identification data and the identification cards are used as information carriers on the e-form lottery tickets. Afterwards, the data on existing identification cards is transferred to the lottery part and a data set on the correspondence between numbers of the e-form lottery tickets and numbers of the identification cards is formed. To this effect, the formula (n M+C)mod T = K is used:, n represents a checked number of a lottery ticket, mod represents a manipulation for defying the excess of division, M, C, T and K represent the numbers, constituting multitude of functional parameters, wherein K is any number ranging between 0 and T-1, T= N/win, N is a total amount of ticket numbers, a win is a required number of advantageous tickets, M, C, T are relatively prime numbers, M and C are greater than a largest observation of a number out of N. The inventive method makes it possible to involve the owners of the identification cards in the lottery and ensure safety and anonymity thereof.
