  • A Straight (single number) bet pays 35:1, so a $10.00 wager returns $360.00 on a win.
  • Your probability of winning any single spin is 2.70%, meaning you can expect to win roughly 2.7 times out of 100 spins.
  • Over 100 spins at this stake, the expected total loss is $27.03 (2.70% house edge applied to total wagered).

Next stepEuropean roulette has a 2.70% house edge. If you can find French roulette with La Partage rules, even-money bets face only a 1.35% edge.
