On the first hole, Player A scores 4, B makes 5, C makes 5, D makes 6. It works like this: Let's say the ace bet is for $2 and the duece bet is for $1. Ties for either the ace or the duece mean that no money is paid for that bet on that hole carryovers are optional at the discretion of the group members (decide before the round starts). The ace bet is usually worth twice the duece bet, but groups can agree on any amount.
On each hole, the low score (the 'ace') wins an agreed upon amount from the other three players, and the high score (the 'deuce') loses an agreed upon amount to the other three players. Aces and Deuces, sometimes called Acey Ducey, is a betting game best for groups of four golfers.
