Taking turns, the players shrink their opening scores using their darts. Each player should try to achieve the highest score possible in his earlier turns. The bigger the score, the faster the shrinking of the initial score advances.

For a “double-in” game, the first player must first hit any double on the board before he begins counting his score. It goes the opposite for a “double-out” as the players need to “get out” by hitting a double that would correspond to the exact balance of their diminished points. However, in “straight-out,” no double hits are needed to finally bring the score to zero or to commence the counting of points.

“Getting in” means hitting the first score. On the contrary, “getting out” denotes throwing the final darts to finally bring the score to zero. The first player who comes up with a zero wins.
