Roulette Strategies, Odds & How to Study the Wheel

Foundations before systems

Start with the math, then the systems

On red/black, a single-zero wheel keeps about 2.7¢ of every dollar wagered; double-zero keeps about 5.3¢. The cards below show the split, then a typical noisy session path.

How roulette works

Wheel math

Red / black house edge

1:1 payouts · edge comes from the zero(s)

Single-zero wheelEuropean / French

2.7%

house edge · about $2.70 per $100 wagered

37 pockets · numbers 0–36

Some French-rule tables: if zero hits on red/black, half the stake returns (La Partage) or the bet is held one spin (En Prison) — effective edge about 1.35%.

Double-zero wheelAmerican

5.26%

house edge · about $5.26 per $100 wagered

38 pockets (0 + 00) · same 1:1 payouts, worse true odds
