When you walk into a casino looking to play roulette, the first thing to take stock of is the style of roulette wheel. Your roulette strategy will vary depending on what sort of wheel you play on. There are basically three types: American, French, and European. The main difference, and the most important to roulette players, is the number of zeros on the wheel.
The European Roulette Wheel, featuring one “single zero” space and no “double zero”, changes the house edge so that it is in favor of the roulette player. This means the European style roulette wheel offers 37 numbers (0 – 36). Alternatively, the American Roulette odds are based on a wheel whose odds favor the house. American roulette wheel features both a “single zero” and a “double zero” space, increasing the number of available slots to 38. You wouldn’t think adding a single slot on the wheel makes a big difference, but it does. Here’s why:
The basic mathematical odds of a particular number appearing on a single zero or “European” roulette wheel are 37 to 1. On a classic American roulette wheel, offers the odds of a number coming up at 38 to 1. Regardless of which style of wheel you’re playing on, roulette pays out 35 to 1 for a single number bet. When you look at the pure numerical odds, it is easy to figure out where the casino is making its profit. On an American Roulette Wheel, there is a probability of 1 / 38 that the roulette player wins that 35 times payout , and a 37 / 38 chance that the player loses their entire bet. Do the math on that, and you come up with a house edge of 5.26%. In layman’s terms, for every $100 a player bets, that player will lose about $5.26 over the course of time.
Due to the fact that the odds are better with a European roulette wheel, which offers one less numerical spot to bet on, there is a 1 / 37 chance that the player wins a 35 times payout, and a 36 / 37 chance that the player loses the entire bet. This sets the house edge at just 2.7%, which means you’ll only stand to lose $2.70 for every $100 bet.
