Sixty-six cards are numbered from 3 to 30 in multiples of three, with each number appearing on several cards. Players take turns playing cards onto one of two discard piles so that the number of the card played is either 3 greater than or 3 less than the top card in the pile. Draw a card if you cannot play. The first player to shed his hand wins. There also is a speed version with simultaneous play.
