We know that “roulette” is French for “little wheel,” though the origin of the game is still fairly mysterious. There are two popular forms of roulette: one called American and one called French or European. Here’s a quick look at the odds of European roulette and the proper roulette strategy based on the features of the European roulette game rules.
The only difference between American and European roulette is a single space on the betting surface and roulette wheel. In European roulette, there is only a single zero space. American roulette wheels contain two symbols based on the zero: a single-zero symbol and a double-zero symbol.
It may seem like such a small difference can’t possibly impact the odds and game play of European roulette all that much, but think of it this way: since there are 37 slots on a European-style roulette gaming wheel (36 digit spaces and the single-zero symbol) and 38 total gaming slots on an American roulette wheel, your odds are much better when you play with a European roulette wheel .
How does the addition of a single space on the roulette wheel affect the game’s odds? A single zero roulette wheel gives the player odds of 36 to 1 for any single number space on the roulette wheel. Since the American roulette wheel offers odds of 37 to 1, the difference in expected outcome is huge.
All roulette games pay 35 to 1 for a single-number bet, which means we can calculate the house edge on American roulette at 5.26%. What does that mean for your bankroll? If you bet $100 on American roulette in an hour, you can expect to lose an average of $5.26. The same edge for European roulette is just 2.7%, so a player betting $100 in an hour should only lose about $2.70 on average .
How can you use this fact to play with better online roulette strategy? It’s simple: don’t bet on American roulette wheel. Roulette players who place bets on American Roulette wheel are placing sucker bets, especially if there’s a European style wheel at the table up the block.
