Responsible gambling

Play for fun — never for money you need

SystemAnalyzer is an educational tool. We show what roulette systems really do, and the most important result is the same for all of them: no system beats the house edge. If you play roulette for real, these are the rules worth keeping.

Before you play

• Set a budget you can afford to lose, and treat it as the price of entertainment — not an investment.
• Set a time limit and a stop loss before the first spin, not during the session.
• Never chase losses. Raising your bets to win back what you lost is how most bankrolls disappear — and it is exactly what progression systems do.
• Never borrow or use money meant for bills, rent or savings.
• Don't play when you are upset, tired or have been drinking.
• Take breaks, and walk away when you reach your limit — win or lose.

Signs that gambling is becoming a problem

• You spend more money or time than you planned, again and again.
• You gamble to win back losses, or to escape stress or low mood.
• You hide your gambling, or feel anxious when you can't play.
• It affects your money, work, sleep or relationships.

If any of this sounds familiar, you are not alone, and help is free and confidential.

Why systems don't fix the odds

Every spin is independent — the wheel has no memory. A progression system only changes how you win and lose: many small wins, and now and then one large loss. Over time the house edge (2.7% on a European wheel, 5.26% on an American one) takes its share of every bet. Our simulations show exactly this for every system — see How we test.
