Select your bet, then pull the lever. You bet is how much money you spend when you pull the lever. Pressing "MAX" will set your bet to the maximum amount of money you can spend without going completely broke. If you win, you get double the amount you bet back. Alternatively, you could just set your bet to 0, meaning you don't gain or lose money, and just play for fun. The probability of winning on any given pull is ~0.29% due to the fact that the machine is not rigged. In a real slot machine that you'd find in a casino, your chance of winning is typically around 1 in 5 million.
