According to the prize distribution rules, during the prize distribution period of the second prize, 5 million yuan will be spent from the two-color ball adjustment fund for prize distribution in each period, but not all the second prizes will be divided equally according to the note, but the second prize of the "Lucky Blue Ball" won in the current period will be divided equally according to the note, and the single note bonus will be up to 5 million yuan. The so-called "lucky blue ball number" refers to 1 lucky blue ball numbers shaken by the same lottery machine from the remaining 15 blue ball numbers after shaking out the basic winning number of the blue ball in each period, which is used as the special number for awarding the second prize in the current period. If the blue ball number of the lottery bet that won the second prize matches the special number of the lucky blue ball, the second prize will be won. Need to remind lottery friends that the lucky blue ball number is only valid for the second prize of the current period. For example, in a conventional two-color ball, a blue number will win the 5 yuan Prize, but if the lottery player only wins the lucky blue ball number, he will not win the 5 yuan Prize. The lucky blue ball number is only the key to judge whether the second prize can participate in the bonus distribution, and has nothing to do with the winning conditions and bonus regulations of other prizes.
