How the Dart Calculator Works

1. Game Types Explained

• 501: Start at 501 points. Finish on any double (double-out).
• 301: Start at 301 points. Double-out required.
• 301 Double-In: Double required to activate scoring + double-out finish.

2. Recording Throws

• Click segments on the dartboard to log scores:
  • S20 = Single 20 (20 pts)
  • D20 = Double 20 (40 pts)
  • T20 = Triple 20 (60 pts)
  • BULL = Single Bull (25 pts)
  • BE = Double Bull/Bullseye (50 pts)
• Special Buttons:
  • MISS: Zero-point throw
  • UNDO: Remove last action

3. Scoring Rules

• 3 darts per turn per player
• BUST Conditions (turn invalid):
  • Score < 0
  • Ends at 1
  • Finishes without double
  • (For 301 Double-In): Scoring before hitting first double
• Auto Revert: Score resets to pre-turn value on bust

4. Checkout Hints

When finish is possible in 2-3 darts: "Checkout: T20 T20 D15" (Uses standard dart notation)
