European roulette is the most common version of the game and is encountered in virtually every online casino. A European roulette is played on a 37-pocket wheel with a single zero, and has a betting area for standard bets as well as a racetrack for placing neighbors and call bets. The table layout and a mutual arrangement of the wheel and betting areas may vary in minor details depending on the game developer, but the game’s logic remains the same. A player can normally place seven types of inside bets (straight, split, street, etc.), five types of outside bets (Low/High, Red/Black, etc.), and a number of call bets (yet there are no call bets in some rule variations of European roulette). A house edge for European roulette is 2.7% which is twice as low as in American roulette. The game is developed by many software providers such as Microgaming, NetEnt, iSoftBet, Playtech, and more.
