European roulette
Single-zero roulette. Usually the baseline rule type for UK online roulette comparisons.
Rules
Roulette rules and minimums
A low minimum is only useful when the rule type is clear. The directory stores rule type beside the stake fields so a cheap table is not mistaken for a better table.
French roulette
Single-zero roulette that may include La Partage or En Prison on even-money bets. The table rules must confirm this.
La Partage
An even-money rule where half the even-money stake is returned when zero appears. Only mark it when the table rules confirm it.
En Prison
An even-money rule where the stake can be imprisoned after zero. Only mark it when the table rules confirm it.
American and triple-zero
Extra zero pockets increase the house edge. These formats should never be blended with single-zero records.
RNG, live, auto, electronic, multiplier
Format changes matter because the same operator can show different minimums and rules across different roulette products.
Systems note
Roulette systems do not change the house edge. They change stake progression, volatility, table-cap exposure, and bankroll path.
