    Roulette: every payout, every probability, one real decision

    Roulette is the most honest game in the casino once you see the trick: every bet on the layout carries the same edge, set entirely by how many zeros the wheel has. Picking the right wheel is the whole game. Here are the rules, the payouts and the real probabilities behind them.

    How it works

    A wheel with numbered pockets, a ball, and a betting layout. You place chips on numbers or groups of numbers, the ball lands where it lands, and winning bets pay fixed odds. There is no skill element after the bet is placed: no decisions, no technique, nothing to practise. That is not a criticism; it is why the game is relaxing.

    The entire mathematical difference between tables is the zero count. A European wheel has 37 pockets (0–36); an American wheel adds a 00 for 38. Payouts are identical on both (a straight number pays 35:1 either way), so the extra pocket is pure house margin. Same bets, same payouts, double the price.

    The payout chart

    European single-zero wheel. On an American double-zero wheel every edge below reads 5.26%. Every bet on a given wheel costs the same — that is the table’s most useful row.

    The even-money bets, honestly

    Red/black, odd/even and high/low feel like coin flips. They are not, quite: 18 winning pockets out of 37 is a 48.6% chance, and the missing 1.4% is the zero, where every even-money bet loses. Some European live tables soften this with la partage, returning half an even-money stake when zero hits, which cuts the edge on those bets to 1.35%. That is the cheapest roulette sold anywhere. If a lobby offers a “French roulette” table, that is usually what the name means, and it is worth choosing.

    Is there a strategy?

    No betting pattern changes the edge, because every bet on the layout already costs the same 2.70%. Progressions like Martingale rearrange your losses; they cannot shrink them. We pulled the systems apart with worked numbers in the roulette strategy reality check, the honest version of the page every system-seller writes. The two real decisions are the wheel (single-zero) and the rule (la partage if offered). After that, bet whatever pattern is fun.

    What players get wrong

    Watching the results board. Every live table shows the last dozen numbers, and the streaks look meaningful: five reds, surely black is due. The wheel has no memory; the probability of red on the next spin is 48.6% after five reds, after fifty reds, always. The board exists because it sells bets, not because it predicts anything.

    Questions players ask

    What is the best bet in roulette?

    On a given wheel they are all the same price: every bet on a European layout costs 2.70% and every bet on an American layout costs 5.26% (bar one even worse five-number bet). The only genuinely better bets are even-money bets on a la partage table, at 1.35%. Pick the wheel and the rule, not the bet.

    Why is American roulette worse than European?

    The 00 pocket. Both wheels pay a straight number at 35:1, but the American wheel has 38 pockets to the European 37, so the same payout buys a worse probability. The edge nearly doubles, from 2.70% to 5.26%, for an identical-looking game.

    Are online roulette wheels rigged?

    Not at a licensed casino. RNG roulette runs on certified, lab-tested builds with locked probabilities, and live wheels are physical equipment under camera. The house does not need to rig anything; the zero already pays for the lights. Our scores only cover regulated casinos where that certification is enforced.

    Edges quoted are the standard published figures for the stated rules; where a paytable varies the range is given rather than a single invented decimal. The full game-by-game comparison lives on the house edge board.
