The invention relates to methods for organizing and conducting draw-based lotteries. The technical result is that of providing for the random distribution of wins among accepted bets without the use of external sources of randomization such as lottery drums or random (pseudorandom) number generators, and exclusively by means of the random play behaviour of the lottery participants themselves. In the course of a lottery, participants place lottery bets using mobile telephones or the Internet, or by purchasing and filling out tickets. After close of betting, the organizers determine, according to the accepted bets, the frequencies with which game combinations will be met in the accepted bets, and use the resulting random distribution of frequencies when determining wins. For this purpose, a pre-set algorithm for the generation of wins is applied, having the said random distribution of frequencies at its input. For example, lottery bet wins can be inversely proportional to a certain positive degree of the frequency of their game combinations. The invention makes it possible to conduct draws with a predetermined number of accepted bets. Draws can be conducted continuously by carrying bets placed after completion of one draw over to the next draw.
