The latter is a derivative and allows bettors to place spread bets on portions of games, such as the first half as exemplified above, the second half, or the third quarter in a basketball game.Ĭustomers will sometimes find derivatives published on the front page of a sports category, but often they’ll have to click or tap on an individual game and dig a bit to find them. Customers who use the BetMGM web interface will notice it posts a spread for the entire game and one for the first half.
