501 Singles

Each player starts on 501 points. Players subtract the score of each three-dart visit from their total.

The goal is to reach exactly zero. The final dart must land in a double segment or the bullseye. If a player scores more than the remaining total, leaves 1, or reaches zero without a double, the visit is bust and the score returns to what it was before the visit.

In club events, the winner is usually decided by legs, sets, or final event position depending on the league format.
