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.

Predicting a slot machine's payout is not possible, as modern slot machines use random number generators to determine the outcome of each spin. These random number generators ensure that each spin is independent of the previous one, making it impossible to predict the outcome with certainty.

It's a 9 chip bet covering 16 numbers either side of the zero, so a 17 number bet in total. In the example above, the blue chips are 5s and the pruple chips are 10s. The proper name for this bet is Grand Voisins du Zro: it's 17 numbers between (and including) 22 and 25 on a European Roulette Wheel.
