Roulette variants are very obvious when comparing the wheels. There are two types of roulette, with the two types of roulette being American and European roulette. The difference between the two types is the number of 0’s on the wheel. You can see the obvious when looking at the wheel before playing at the roulette wheel. American is known as having two 0’s, which contains the numbers zero and also the double zero. American roulette also uses non-value chips, non value means that all chips belonging to the same player are of the same value determined at the time of purchase.

All the players chips could be five dollar chips or ten dollar chips and so on. And then when you look at European roulette, this game uses standard casino chips of differing values as bets, which can make the game more confusing for both the croupier and the players. It is generally the color of the chips that will reveal the value of the chip to the dealer or the players who are all on the same table. A traditional European roulette table is also much larger than an American roulette table, and the croupier uses a long tool called a rake to clear out the chips and to distribute winnings.

There are three fundamental styles of roulette; American, European and French.

• American Roulette This is played with a wheel having two zero slots, which augments the house edge.
• European Roulette This is played with a single zero wheel and the same betting layout as the American version.
• French Roulette This is played with a single zero wheel. Though the appearance of the layout is different for the "outside" bets, the rules of betting remain the same.
