Roulette Odds, Payouts & House Edge — The Honest Guide

The one number that explains everything: house edge

Before the bet types, get this concept locked in, because it powers the entire article.

A single-zero (European) wheel has 37 pockets: the numbers 1 to 36, plus a green 0. If roulette were a perfectly fair game, a winning straight-up bet would pay 36:1 — that is the true odds against you. Instead, the casino pays 35:1. That missing unit is the house edge, and on a European wheel it works out to exactly 2.70%.

Think of it as a small, constant tax on every bet. For every €100 wagered over the long run, the wheel keeps around €2.70 and returns €97.30. That is the RTP of 97.30% you will see quoted.

The beautiful (and brutal) part: on a European wheel, *every* standard bet carries the same 2.70% edge. Straight up, red/black, a corner of four numbers — it makes no difference to the long-run maths. The green zero is the source of the edge, and it taxes every wager equally. So no bet is ever "smarter" than another in terms of expected value. They just feel different.

• Low edge = the game gives you more back over time.
• The edge is a long-run average, not a prediction of your session.
• Nothing you do at the table changes it. We will prove that later.

Inside bets vs outside bets — what the two halves of the table mean

The roulette layout splits cleanly into two zones, and learning the vocabulary makes everything click.

Inside bets are placed on the grid of numbers itself — on a single number, on the line between two, on the corner where four meet. They cover few numbers, so you win rarely, but the payouts are big.

Outside bets sit in the boxes around the edge — red or black, odd or even, the dozens and columns. They cover lots of numbers, so you win often, but the payouts are small (usually 1:1 or 2:1).

Here is the mental model that matters most: inside = rare-but-big, outside = frequent-but-small. Neither is "better". On a European wheel both carry the same 2.70% edge. What you are really choosing is volatility — the rollercoaster shape of your bankroll.

A player hammering single numbers might sit through 30 cold spins then land a 35:1 hit. A player on red/black wins close to half the time but never sees a thrilling payout. Same edge, completely different ride. If you enjoy slots, you will recognise this trade-off — it is the same logic as slot volatility, just on a wheel.

This is the single most useful thing to know before you place a chip: decide whether you want frequent small wins or rare big ones, then bet accordingly. The maths is identical either way.

The full roulette payout chart (inside bets)

Here are the classic inside bets, what they cover, and what they pay. Odds shown are for a European (single-zero) wheel.

• Straight up — one number. Pays 35:1. Win chance: 1 in 37 (~2.7%).
• Split — two adjacent numbers, chip on the line between them. Pays 17:1. ~5.4%.
• Street — three numbers in a row. Pays 11:1. ~8.1%.
• Corner (square) — four numbers meeting at a corner. Pays 8:1. ~10.8%.
• Line (six-line / double street) — six numbers across two rows. Pays 5:1. ~16.2%.

Spot the pattern? Every payout is built from the same formula: cover more numbers, win more often, get paid less. Multiply the win chance by the payout-plus-one and you land on roughly 0.973 every single time — that 2.70% edge, hiding in plain sight in every row of the chart.

There is one bet to actively avoid, and it only exists on American wheels: the five-number bet (0, 00, 1, 2, 3), which pays 6:1 and carries a nasty 7.89% house edge — by far the worst wager in the game. Skip it.

Outside bets — the steady, even-money side

Outside bets are where most beginners (sensibly) start, because they win often and are easy to read.

The 2:1 payers (cover 12 numbers each): - Dozens — 1st (1–12), 2nd (13–24), or 3rd (25–36). - Columns — one of the three vertical columns down the layout.

Each covers 12 of the 37 pockets, so you win about 32.4% of the time and double your money when you do.

The even-money bets (1:1, cover 18 numbers each): - Red or Black - Odd or Even - Low (1–18) or High (19–36)

These are the famous "coin flip" bets — except it is not quite a coin flip. Each covers 18 numbers out of 37. The green zero belongs to neither side, so your real win chance is 18/37 = 48.65%, not 50%. That missing 1.35% on each side is the house edge doing its quiet work.

Even-money bets are the gentlest way to play: low volatility, long sessions, lots of small wins and losses. They are also the bets that unlock the best deal in all of roulette — the French rule we are about to meet. If you like the slow-burn, low-variance style, you will recognise it from low-volatility play elsewhere on the site.

European vs American vs French — choose your wheel wisely

This is the most important practical decision you make, and it is decided before you place a single chip.

European (single zero, 37 pockets): house edge 2.70%. The standard, sensible choice.

American (double zero, 38 pockets): the wheel adds a second green pocket, 00. That extra pocket does not change any payout — a straight-up still pays 35:1 — but it dilutes your odds across 38 numbers instead of 37. The result: the house edge nearly *doubles* to 5.26%. Same game, same table felt, almost twice the long-run cost. If both are offered, there is no reason to ever choose American.

French (single zero + La Partage): the connoisseur's wheel. It uses the European 37-pocket layout but adds the [La Partage] rule. When the ball lands on zero and you are on an even-money bet (red/black, odd/even, high/low), you get half your stake back instead of losing it all. That single mercy halves the edge on those bets to just 1.35% — the lowest in the building.

A related rule, En Prison, instead "imprisons" your even-money bet for one more spin to win it back; it lands at the same 1.35%.

The ranking is simple: - French even-money bets (La Partage): 1.35% — the best bet in roulette. - European, any bet: 2.70% — the solid default. - American, any bet: 5.26% — avoid.

Pick the wheel before you pick the bet. It matters more than anything else you will do.

Why no system beats roulette (the honest bit)

You will meet a lot of "systems" — Martingale, D'Alembert, Fibonacci, the Paroli. Here is the uncomfortable, mathematically airtight truth: none of them changes the house edge. Not by a fraction of a percent.

The reason comes down to one word: independence. Every spin is a fresh event. The wheel has no memory. Red landing ten times in a row does *not* make black "due" — the eleventh spin is still 18/37 for black, exactly as it was on spin one. Believing otherwise is the famous gambler's fallacy, and casinos quietly love players who fall for it.

Take the Martingale, the most popular system. You double your bet after every loss, so the eventual win recovers everything plus one unit. Sounds bulletproof. It is not. Two walls demolish it:

• Table limits. After a handful of losses, doubling sends you past the maximum bet. You physically cannot continue the sequence.
• Your bankroll. A run of 8–10 losses on an even-money bet is not rare over a session — and the bet required to recover it is astronomical. One bad streak wipes out dozens of tiny wins.

The deeper point: a betting system only rearranges *how* you stake across spins. It cannot turn a series of negative-expectation bets into a positive one. Adding up negative numbers in a clever order still gives you a negative total. Every system trades a high chance of a small win for a small chance of a catastrophic loss — and the edge collects its tax throughout.

Systems can absolutely make a session more *fun* by shaping the swings. Just go in knowing they are bankroll-management styles, not money-printers. Anyone selling a guaranteed roulette winner is selling the gambler's fallacy with a price tag.

Putting it together: how to play roulette smartly for fun

You cannot beat the edge, but you can absolutely play in a way that maximises entertainment per chip. Here is the sensible playbook.

• Choose the right wheel. French or European every time. Walk past American tables.
• Match the bet to the thrill you want. Want long sessions and frequent small wins? Even-money outside bets, ideally with La Partage. Chasing the 35:1 dopamine hit? Inside bets, smaller stakes, and patience.
• Set a budget per session and treat losses as the cost of entertainment, not an investment you expect back. The maths guarantees a slow drift down over time; the fun is the product.
• Ignore the scoreboard. Those displays of "hot" and "cold" numbers are pure theatre. Past spins tell you nothing.

Roulette sits in a wider family of casino games, and once the maths clicks here it transfers everywhere.
