The two-color ball adjustment fund includes 2% of total sales, overdue tickets and floating prize balance. The adjustment fund is used to pay unforeseen bonus expenditure risks and set up special prizes.

When the single-note bonus of the first prize is lower than that of the second prize, the sum of the total prizes of the first prize and the second prize will be divided equally by the winners of the first prize and the second prize; When the single note bonus of the second prize is less than twice that of the third prize, the adjustment fund will supplement the single note bonus of the second prize to twice that of the third prize.

Other provisions of the two-color ball:

When the two-color ball draws a prize in each issue, after the sales data is sealed, the lottery number is determined by the lottery machine under the supervision of the notary. In the lucky draw, first shake out 6 red ball numbers, and then shake out 1 blue ball numbers. After each lottery, the lottery center and the provincial lottery institutions shall announce the lottery number, the total sales amount of the current period, the winning situation of each prize level and the fund balance of the prize pool to the public, and notify the sales outlets of the lottery results.

The two-color ball determines the corresponding winning qualification according to the coincidence of the single bet number selected by the buyer (double bet and bold drag bet are calculated according to each single bet included) and the current lottery number.
