Most (but not all) Fruit Machines have a repeats feature, which allows the player to repeat other features or winning spins.
It works by simply flashing yes or no and the player must use skill (well fast reactions and great timing) to hit the stop button whilst the YES is lit up so that they can repeat the winning feature.
Many of the Fruit Machines will have a Repeat feature that let you have the chance of repeating certain features or wins. The option is chosen when a lighted button flashes Yes or No and you have to hit the button when you think it will land on Yes.
If this feature is available for repeating wins, you have a chance of winning a good deal of money by using it as often as you can.
