Same edge, different ride

On a European wheel every bet costs the same 2.70% — what changes is volatility. The Low (1–18) bet’s standard deviation is 1.00 per $1: the smoothest ride on the felt — small swings, near-coin-flip rhythm. At $10 a spin over 100 spins you should expect to pay about $27 in edge, with session swings of roughly ±$100 one standard deviation around it.

Manque — the low half

French tables label 1–18 manque (“missed” — the ball fell short). On the rim low numbers interleave with highs by design, so “betting low” buys no physical arc — unlike sector bets. Pair it with high for a near-full lattice and you’ve built an expensive coin-flip: two edges paid, 5.41% of turnover.

Frequently asked

What does the low (1–18) bet pay in roulette?
1:1 — a winning $10 bet returns $10 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 low (1–18) bet?
48.65% on a European wheel (1 in 2.1 spins) and 47.37% on American, because of the extra 00 pocket.
Is low (1–18) 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 1.00), not the price. The only real “good bet” decision is the wheel: French even-money at 1.35% is the cheapest game in the house.
