When it comes to basketball games, the calculation of results for all bets usually includes the overtime period unless explicitly stated otherwise. This means that bets on the final outcome of a basketball game, including point spread and total points, will be settled based on the final score at the end of overtime.
However, it's important to note that bets on the winner of the match with a "draw" option are only offered based on the regular time and do not include overtime. This means that if a basketball game ends in a tie after regular time, the bet will be settled as a draw, and the original stake will be returned.
It's also worth mentioning that different sportsbooks may have slightly different rules and regulations when it comes to basketball game calculations. Therefore, it's always essential to read and understand the specific terms and conditions of the sportsbook you're using before placing any bets.
