Principles of jackpot drawing
Throughout the history of the "Russian Lotto" jackpot was determined by two principles, which are quite similar, but the probability of success in them varies greatly. You will hardly find this information in the rules of the game on the Stoloto website, however, it is contained in the order of the Ministry of Sports of the Russian Federation from 19 August 2016 r. № 982 "On the approval of the conditions of the five drawing all-Russian state lotteries in support of the development of physical culture and sports". The document was signed by the former Minister of Sports Vitaly Mutko.
In particular, in the section "Conditions of the fourth drawing all-Russian state lottery in support of the development of physical culture and sports", two algorithms for drawing a jackpot are given. This is stated in paragraph 14.21 section.
Algorithm # 1
Jackpot get those tickets, in which 15 numbers from 30 in two playing fields coincide with all fifteen dropped kegs for the first 15 moves.
In this case, the probability of winning is 1 chance from almost 23 quadrillion, that is, insignificant 4,37-15%.
Algorithm # 2
Win tickets, in which, on the move determined by the operator, the numbers dropped out during the draw coincide 15 numbers from 30, located in the two playing fields of the ticket.
In this case, the probability can increase significantly, but for a single lottery participant it will still remain insignificant - 1 chance out 295 232 118, it is approximately 3,4-7%.
Lottery organizers change these two ways from draw to draw at their discretion. Since the first way to win the jackpot in the "Russian Lotto" is almost impossible, then this one is used rather to accumulate a large prize size. Then the second method comes into force - then the super prize can already find its owner.
Before, how in 2016 the second principle appeared, hitting the jackpot didn't work for several years, since the mathematics simply did not allow it. After the introduction of the second principle, they began to receive superprizes much more often.
