Where you place your chips is almost everything in roulette. Knowing how payouts work across straight-ups, splits, and outside chances separates playing with purpose from playing blind. Every bet on the layout carries a fixed payout ratio the casino sets in advance; those ratios don’t shift from one session to the next.
What does shift is the probability tied to each bet type, and that gap between what the house pays and what the math says your bet is actually worth is where the house edge hides. American roulette runs a wheel with 38 pockets: numbers 1 through 36, a single zero, and a double zero. European roulette drops the double zero down to 37 pockets.
That one pocket pushes the house edge from 5.26% on the American wheel down to 2.70% on the European version. Knowing those numbers before your first chip hits the felt keeps your expectations honest.
Inside Bets: Where the Big Payouts Live
Inside bets land directly on the numbered grid, covering one number or a tight cluster at a time. The narrower your coverage, the bigger the payout ratio , but the worse your odds of actually connecting. A straight-up bet paying 35 to 1 sounds extraordinary. But on an American wheel, your real odds of hitting that number are 37 to 1 against you.
That two-pocket gap : the zero and the double zero is the entire source of the house advantage here. And that gap follows the wheel wherever it goes. Spin one in a casino or spin one in crypto roulette games online, and you’re still up against 38 pockets with one winner. Inside bets demand either a longer bankroll or a shorter session if you don’t want to go broke before your number finally shows up.
Straight-Up and Split Bets
A straight-up bet covers a single number – chip goes in the center of that square, and if the ball drops there, the house pays 35 to 1. So a $10 bet returns $350 in winnings plus your original $10 back. On a European wheel, your probability is 1 in 37; on an American wheel it falls to 1 in 38.
A split bet covers two adjacent numbers (horizontally or vertically neighboring squares) by placing your chip on the shared border between them, and the payout drops to 17 to 1 because you’ve now covered two pockets. Stake $10 on a split and a win returns $170 in profit.
A street bet goes one step further, covering three numbers in a single horizontal row – the chip sits on the outer edge of the row, and it pays 11 to 1. Each step outward in coverage cuts the payout in a predictable pattern; the math stays consistent across every variation.
Corner, Line, and Five-Number Bets
A corner bet covers four numbers forming a block on the grid, chip at their shared intersection, paying 8 to 1. A six-line bet covers two back-to-back rows of three numbers each (six total) and pays 5 to 1. Both of these appear on American and European wheels without any structural difference.
But one inside bet exists only on the American layout: the five-number bet, also called the basket or top-line, covering 0, 00, 1, 2, and 3. It pays 6 to 1 and carries a house edge of 7.89%, noticeably worse than every other bet on the board.
Honestly, most experienced players won’t touch it. The payout structure is stingier than the math warrants even by American-roulette standards, so unless those five specific numbers mean something to your strategy, it’s worth skipping.
Outside Bets: Broader Coverage, Smaller Payouts
Outside bets occupy the wider boxes around the outer perimeter of the numbered grid, and they sweep large sections of the wheel at once. The catch is that broader coverage comes with much smaller payouts – though you’ll hit considerably more often.
This part of the layout is where casual players tend to start, and there’s real logic to that; even-money bets are simple to track and easy to manage within a fixed budget. On a European single-zero wheel, even-money bets carry a probability of exactly 18 in 37 – 18 winning numbers against 19 losing ones.
On an American double-zero wheel, that slips to 18 in 38. Zero pockets don’t pay out on outside bets; they simply take everything, which is how the house collects on every even-money wager in both versions of the game.
Even-Money Bets and Dozen or Column Bets
Even-money bets come in three flavors: red or black, odd or even, and high (19 to 36) or low (1 to 18). Each pays 1 to 1 – stake $10, win $10. These bets cover 18 numbers apiece, which sounds close to half the wheel, but the zero pockets pull the probability below a true 50/50.
Some European casinos offer a rule called “La Partage,” returning half your even-money stake when the ball lands on zero; that cuts the house edge on those bets to 1.35%, which is among the best odds in the building. Dozen bets split the layout into three groups of 12: 1 to 12, 13 to 24, and 25 to 36.
Column bets cover 12 numbers each as well, just arranged vertically rather than by range. Both pay 2 to 1, so a $10 wager returns $20 in profit when it connects. You’re looking at roughly a one-in-three shot at winning, minus the zero pockets – a middle ground between the near-coin-flip of even-money bets and the tight, high-variance world of inside bets.
Conclusion
The principle running through every roulette payout is the same: cover fewer numbers and the house pays you more when you win. Straight-up bets pay 35 to 1 but connect roughly once every 37 or 38 spins on average. Outside bets pay 1 to 1 or 2 to 1 and hit far more frequently. The house edge doesn’t vanish on any of these; it’s baked into every payout ratio on the board. What varies is the swings; inside bets produce wild fluctuations in both directions, while outside bets generate smaller, steadier results. And the American wheel’s extra zero pocket lifts the house edge across every single bet type compared to its European counterpart, so if you’ve got a choice between the two, the single-zero version is the mathematically sounder seat. Keep your bet sizing in line with your actual session budget, and the game stays enjoyable a good deal longer.
