Game Guide
Roulette places numbered wheel outcomes beside a table of inside and outside bets. This hub shows how to read the layout, compare major wheel formats and separate the fixed maths of each bet from claims made by progression systems.
A single-zero wheel and a double-zero wheel do not have the same total number of pockets. That difference changes the probability behind otherwise similar-looking bets, so the wheel format should be checked before comparing odds.
Changing stake size after a win or loss changes the amount at risk, not the probability of the next independent spin. Progression systems can therefore produce larger drawdowns without removing the house edge.
The table name, wheel and rules shown in a live product decide which calculation applies. Do not infer a single-zero, double-zero or French-rule table from a general guide, and do not treat a guide as evidence that a specific roulette variant is currently available.
