The unlock

• One visit: you must hit the bull again in every visit before you can score.
• Until stolen: after your bull you keep the scoring in your next visits too, until another player hits the bull and steals it.
• Any bull: the 25 also unlocks. In All numbers a bull after the unlock scores 25 or 50; with 20 or 19 it gives nothing.

Formats and scoring

• League format (3 players or more): the game goes on until every place is decided.
• Buttons: pick single, double or treble, then the number. The bull glows while you are locked; the numbers that score glow when you are unlocked.
• Keyboard: type the dart (20, D20, T20, 25 or 50, 0 for a miss) and press Enter. D and T set double and treble. U is undo, R clears the visit.
• Scolia: every dart is read for you; the next player throws when you take your darts out.
• UNDO takes back the last dart, then the visits before it. With a Scolia, tap a dart to correct it before you take your darts out.
