When a game goes into overtime, any scores that happen in the overtime period will count towards bets placed on the full game and the second half (this applies to point spread, moneyline and total bets).
Overtime does not count towards any 4th quarter bets.
These rules apply to all leagues.
NOTE: In international basketball (FIBA), teams sometimes play two legs against each other as part of a playoff/tournament. It is possible for an individual leg to end in a tie (the game will not go into an overtime period). In such cases, bets on the moneyline will have no action. Bets on the spread or total will have action and are graded based on the final score of the leg.
