In UK roulette, specific rules distinguish it from other variations, particularly European and American roulette. The game typically features a single zero, which gives players a better house edge compared to American roulette's double zero. Additionally, UK roulette often employs two significant rules known as "En Prison" and "La Partage." The "En Prison" rule allows players to leave their even-money bets in play for the next spin if the ball lands on zero, while the "La Partage" rule enables players to receive half their bet back when zero is hit.
