European Roulette differs from American Roulette by the double zero slot. The game, as originally played, did not have the zero or double zero slots. Both were added after the bingo game was being played without any zero slots. Entities in Monte Carlo added the zero slots to increase the house advantage. When the game originally came to America, it didn’t have the double-zero slots. The double zero slot was added in Las Vegas to make the game acceptable to the house because it increased the house advantage. At the time, the Las Vegas casinos weren’t willing to offer the casino game with only the single zero.

Today, the game can be played both ways, with and without the double-zero slot. The chance of the bingo ball landing in any slot in European Roulette is 1 in 36. In the American version it is 1 in 37. The house advantage is doubled from 2.7% to 5.25%. The player has a lesser chance of winning in the American version. There are other differences between the two versions. The European table is larger than the table used in the American version. Also, the chips are different in the two versions. The regular casino chips are used in the European version. In the American version each players has their own chips and chip colors are used to distinguish between players.
