Challenge Rule
The Scrabble rule allowing a player to dispute an opponent's word; if the word is invalid it is removed, otherwise the challenger loses a turn (under standard double-challenge rules).
Why it matters
Challenge rules govern the entire phoney sub-game. Knowing the variant in play (single, double, void) changes correct strategy.
Examples
- Tournament play commonly uses double-challenge: invalid word comes off, valid word costs the challenger a turn
Best practices
- Confirm the challenge variant before the first move
- Track your own challenge accuracy as a calibration metric
