Hello, users, here is a small game, that is, set 9 prizes from 1 to 9 * * *, then set 0 to 4 * * 5 paper balls to draw a paper ball, multiply the paper ball by 2 and add 1 to get the corresponding prize. You can set even numbers as good prizes and odd numbers as general prizes, because only odd numbers can win prizes. Thank you for your support of Baidu Know Application. Please adopt it. Thank you.
