As an example, let's use a Yankees-Red Sox game with a total of 10.5 and odds (or juice ) of -120 to the Over and +100 to the Under. If you place aR$100 bet on Over 10.5, you stand to collectR$183.33 (originalR$100 bet, plusR$83.33 in winnings).

This means that if both teams score 9 or more combined runs the result counts as Over. If less than 9 runs are scored, the result counts as Under. With odds of -110, you have to betR$110 on either team to winR$100 in profit. In this case, the payout (odds) for both the Over (O) and the Under (U) is the same: -110.

The machine accepts any credit bets. It then randomly determines the position of the symbols on the video display to produce an outcome, which is completely unrelated to the previous game's outcome. If the machine determines a win, credits are paid.

Fruit machines are popular because of their relatively high payout rate when compared with other forms of game machines. When fruit machines payout, they typically return between 70-98% of money gambled.
