Straight up bet in roulette
A straight up bet is a roulette wager placed on one single number, zero included, that pays 35 to 1 when the ball lands in that pocket. A €10 chip on 17 that wins returns €350 in profit plus the original stake. It is the narrowest bet on the layout, so it wins least often and pays most when it does.
Where the straight up bet sits on the table
The chip goes in the centre of a single number on the grid, without touching any line, which is what separates it from a split or a corner. Online and live casino tables mark the same spot, and the bet slip normally labels it as a straight or a single number.
Players often confuse it with a bet that is “safe” because the payout is big. It is not.
How the 35 to 1 payout is priced
The paytable assumes a wheel of 36 numbers, so each green pocket the wheel adds is margin for the house. The figures below follow directly from pocket counts and the standard 35 to 1 payout.
| Bet and wheel | Pockets | Win chance | Payout | House edge |
|---|---|---|---|---|
| Straight up, no zero (theoretical) | 36 | 2.78% | 35:1 | 0% |
| Straight up, European | 37 | 2.70% | 35:1 | 2.70% |
| Straight up, French la partage | 37 | 2.70% | 35:1 | 2.70% |
| Straight up, American | 38 | 2.63% | 35:1 | 5.26% |
| Straight up, triple zero | 39 | 2.56% | 35:1 | 7.69% |
| Split, European | 37 | 5.41% | 17:1 | 2.70% |
What the house edge means over many spins
On a European wheel, a player who stakes €1 on one number for 37 spins expects one win of €35 against 36 losing euro, leaving a shortfall of €1, which is the 2.70% edge as a long-run average rather than a forecast for any session. La partage returns half of even-money stakes on zero, so it does not help a straight up bet.
A number that has not come up for a hundred spins is no more likely on the next one.
Each spin is independent, and the split row shows that covering more numbers changes how often the bet wins, while the edge stays fixed by the wheel.
