The over/under may be the simplest of bets to understand. The over/under relates to the total amount of points scored in a game and the bettor wages if there are going to be more or less than that total. You bet if the total will be over or under the number given.
So let’s say they play this make-believe game that an over/under total of 45 and the final score of the game is Dallas 31, New York 28. That would mean the total for the game would be 59, and everyone that bet on over 45 would win and everyone that bet on under 45 would lose.
