The numbers, all three wheels
| Wheel | Win probability | Hits | House edge | Std deviation / $1 |
|---|---|---|---|---|
| European | 2.70% | 1 in 37.0 | 2.70% | 5.84 |

Same edge, different ride
On a European wheel every bet costs the same 2.70% — what changes is volatility. The Straight Up bet’s standard deviation is 5.84 per $1: a rollercoaster — long droughts, big spikes. At $10 a spin over 100 spins you should expect to pay about $27 in edge, with session swings of roughly ±$584 one standard deviation around it.

Frequently asked
What does the straight up bet pay in roulette?
35:1 — a winning $10 bet returns $350 profit plus your stake, on every wheel type. What differs between wheels is how often it wins, not the payout.
What are the odds of winning a straight up bet?
2.70% on a European wheel (1 in 37.0 spins) and 2.63% on American, because of the extra 00 pocket.
Is straight up a good bet?
It costs exactly the same edge as every other bet on the same wheel — 2.70% European. Choose it for the volatility profile (SD 5.84), not the price. The only real “good bet” decision is the wheel: French even-money at 2.70% is the cheapest game in the house.
