Overview
Every hole has a hero and a goat. The outright low net (the ace) wins from everyone. The outright high net (the deuce) pays everyone.
Ties
A tie for low means no ace; a tie for high means no deuce. Both can happen on the same hole.
Ties carry
A house rule, off unless you turn it on: a tie for low adds that hole’s ace to the next outright low, and a tie for high adds its deuce to the next outright high. Still carried after the last hole, nobody gets it.
Bets
Set the ace and deuce amounts separately. Aces are usually worth more.
