Older style fruit machines would work purely on the basis of probability in terms of how much money they would pay out. Modern machines are usually set to pay out a certain percentage of any money that is put into them (usually between 75% and 80%).

Place your bet  Place your bet before the game begins. Cash-out at some point  As the game starts and the multiplier increases, the only task is to cash out before the crash occurs, at which point you will lose your bet. End of the game  If you managed to cash out before a crash, you keep your winnings.
