Deuces is a very simple game played with two or more players. Each particpant pays an entry fee and this becomes the "Deuces Pot". When a player achieves a two (aka, "deuce") on a hole, they win a portion of the pot regardless of any other two's on the same hole. The more deuces you make, the more you can win.

Here's an example of how this works. Let's say there are four participants and each player pays an entry fee of $15. The deuces pot is 4 x $15 = $60. The first player achieves two deuces, the second player achieves one deuce and the other two players fail to make any deuces. Since there were three total deuces in the round, each deuce is worth $60 / 3 = $20. So the first player receives 2 x $20 = $40, the second player receives 1 x $20 = $20, and the other two players come up empty-handed.
