How to Play Roulette Online — Bets, Odds and House Edge
Learn online roulette from zero: inside vs outside bets, the real payouts and odds, why European single-zero beats American, and how live roulette settles in USDT on TRON.
The short version, and the one fact that matters
A ball spins around a wheel and drops into a numbered pocket. You guess where it lands, place chips on the table layout, and collect if you're right. That's the whole game. The catch most beginners miss is that picking the right table matters more than picking the right number.
Two wheels dominate. The European wheel runs 0 through 36, so 37 pockets. The American wheel adds a 00, making 38. That single extra pocket nearly doubles the house edge. Always take the European table when it's offered. This one choice moves your expected return more than any betting pattern or hunch ever will.
If you've worked through a table game before, the logic carries over. The payout-versus-odds tradeoff is the same idea you'll find in our baccarat guide and in sic bo. Roulette just spreads it across a busier grid.
Inside bets: big payouts, long odds
Inside bets sit on individual numbers or small clusters of adjacent numbers. Cover fewer numbers and the payout climbs while your chance of hitting drops. Here are the standard payouts on a 37-pocket European wheel.
| Bet | Numbers | Payout | Win chance |
|---|---|---|---|
| Straight | 1 | 35:1 | 2.7% |
| Split | 2 | 17:1 | 5.4% |
| Street | 3 | 11:1 | 8.1% |
| Corner | 4 | 8:1 | 10.8% |
| Line | 6 | 5:1 | 16.2% |
Say you drop $50 straight up on 17 and the ball lands there. You collect $1,750 in winnings plus your original stake back. That payoff is why straight bets feel exciting, even though you'll lose the vast majority of spins. The split and street bets are the middle ground: still rich, a bit more forgiving.
Outside bets: win often, win small
Outside bets cover large groups, so they hit far more often. They're where most newcomers start because a bankroll lasts longer. Red/black, odd/even and high/low all pay 1:1. Dozens and columns pay 2:1.
| Bet | Payout | Win chance |
|---|---|---|
| Red / Black | 1:1 | 48.6% |
| Odd / Even | 1:1 | 48.6% |
| High (19-36) / Low (1-18) | 1:1 | 48.6% |
| Dozen (12 numbers) | 2:1 | 32.4% |
| Column (12 numbers) | 2:1 | 32.4% |
Here's the trap. Outside bets do not carry a lower house edge than inside bets. On a European wheel every bet type sits at the same 2.70%. What changes is variance. Betting red over and over gives you a smoother ride with more frequent small wins, but the math grinding against you is identical. The same return-to-player principle shows up in our RTP explainer and in why the banker bet wins out in baccarat.
The house edge, in plain numbers
The edge comes entirely from the zero. When the ball lands on 0 (or 00), the outside bets lose and the house takes the pot. A European wheel has one zero, which puts the edge at 2.70%. Over time, every $100 you cycle through the table costs you about $2.70.
The American wheel's extra 00 pushes that to 5.26%, almost double, while the table payouts look unchanged. That second green pocket quietly eats your margin. You can check the wheel layouts and probabilities on the Roulette page at Wikipedia if you want the source.
Some European tables add la partage or en prison. When the ball hits zero you get half your even-money stake back, or it stays locked for the next spin. Either rule cuts the edge on even-money bets to roughly 1.35%. Find a table that runs it and you've got the best deal on the floor.
No betting system changes any of this. Martingale doubles your stake after every loss, Fibonacci walks a number sequence, and both just rearrange how your money moves. Neither shaves a single point off the house edge. They reshape your variance, nothing more.
Playing live roulette, and how to start

Most tables run on Evolution, and you'll also find variants like Lightning Roulette that drops random multipliers on chosen numbers each round.
