How to read the tester

A strategy does not change the odds of a single spin: red still comes up 18 times out of 37. What it changes is the shape of a session. Some systems win small amounts often and lose rarely but heavily, others lose a little often and win big rarely.

That is why the tester plays 2,000 sessions with your settings instead of one: the share of sessions in profit, the share that run dry and the worst session tell you more than any promise.

Roulette strategy questions

Can a roulette strategy beat the house edge?

No. Every bet keeps its house edge whatever you bet before or after it. A strategy changes how often you finish a session up, how much you risk, and how long your bankroll lasts.

Which roulette strategy is the best?

It depends on what you want from a session. Martingale and Fibonacci finish most sessions up but lose big when a long losing streak hits. Paroli and 1-3-2-6 risk little per cycle and win rarely. Test them with your own bankroll to compare.

Are betting systems allowed in casinos?

Yes. Casinos do not forbid any betting system; they limit them with a maximum bet per table, which stops a progression like the martingale after a few doublings.
