Send each visit to the oche as a turn of up to 3 darts (formats: S20, D16, T19, SB, DB, or 0). Applies standard bust rules (a bust scores nothing and the turn ends; darts after a finish are ignored; double-out requires a double or inner bull to finish unless double_out is false). Returns remaining, per-turn detail, busts, darts thrown, the three-dart average, a checkout suggestion when one exists, and a CSV of the leg. It is not for cricket or around-the-clock variants, and it does not track multi-leg matches — one leg per call.",
