Call your shots. More or less, 2 to 6 players, all or nothing — up to 50×.
A leg voids when that player has no stat line — inactive, scratched, benched, or the game itself was postponed, cancelled, suspended or forfeited. Same rule pre-game and live.
A void doesn't kill your slip — it shrinks it. Your payout is recalculated at the smaller number of legs that actually counted.
Shrink below 2 live legs — or down to one team on a multi-team slip — and the whole slip refunds instead of grading.
Once a slip settles, a stat correction that comes in later never reopens it.
UFC: if a fight ends early, stats count as they stand; a cancelled or changed fight voids.
