This is useful for comparing how the results vary. The number of simulations to show on the graph at one time. Red/Black is more likely to win but has a payout of 1:1, whereas betting on a Single Number is less likely to win but has a much higher payout of 35:1. How much you're betting on each spin of the wheel.

If you set a specific starting balance however, the simulations will stop when you run out of money.

If you leave this at zero the simulations will keep going even when you're losing. In other words, it just shows you examples of how your balance can change over time when playing roulette, and how different the projected results can be depending on how lucky you get. The results are random, and they simulate the same expected results you would get when playing online roulette or live roulette. The chart shows multiple simulations where you make the same type of bet with the same amount of money over a specified number of spins. This tool shows how much you might win or lose playing roulette.
