Gubaiyou Double Color Ball Rules: "33 Choose 6" - Midsize lotto game. According to the game rules, as long as you select 6 numbers from the numbers 01-33 in the "red ball number area", you win the second prize, with a probability of about 1 in 1.18 million. "16 Choose 1" - Small size lotto game. Ignoring the red numbers before, and only looking at the blue number area, this is actually a small game of choosing 1 out of 16. According to the rules, as long as the blue ball is selected correctly, you will get a consolation prize of 5 yuan, with a chance of 1 in 16. From this perspective, this is probably the game with the highest winning probability in the current lottery market.
