The table layout can be divided into two sections which correspond to the two major types of bets that can be placed. The layouts on American and European roulette tables are largely the same except that the layout in European roulette has only one zero betting box. It is typically covered with green cloth. The layout is the area on the roulette table where the bets are placed. The wheel always spins counterclockwise while the ball is thrown in such a way so that it spins in the opposite direction or clockwise.

There are nine high numbers in black pockets and nine low numbers in red pockets – 20, 22, 24, 26, 28, 29, 31, 33 and 35, and 1, 3, 5, 7, 9, 12, 14, 16 and 18, respectively. On the left side of the zero pocket, the way in which the numbers are arranged is just the opposite. The black numbers on this side are low while the red numbers are high.

On the right side of the zero pocket, you will find nine black numbers and nine red ones – 2, 4, 6, 8, 10, 11, 13, 15, and 17, and 19, 21, 23, 25, 27, 30, 32, 34, and 36, respectively. If you look closely, you will notice that the numbers on the wheel are arranged according to a specific pattern. Numbers 1 through 18 are “low”, while numbers 19 through 36 are referred to as “high”. The numbers can also be divided into high and low. Each pair of odd numbers is followed by a pair of even numbers. Red and black pockets on the wheel always alternate. There are 18 red pockets and 18 black pockets. The numbers are aligned in a seemingly random order. Also, the numbers in the pockets face the inner part of the wheel which is not the case in American roulette. It is important to remember that the sequence of numbers on European roulette wheels differs greatly from that on American wheels. The remaining pockets are marked with numbers 1 through 36.

There is one zero pocket, coloured in green. Unlike American roulette, where there are two zero pockets on the wheel, in European roulette, the wheels have only 37 pockets. The main difference between American and European roulette lies in the number of pockets on the wheel and on the betting layout, respectively. What’s the difference between the two? The rules and the betting options in the two variants are roughly the same with a few small exceptions. European roulette is played predominantly in landbased gambling venues throughout Europe but due to the game’s immense popularity, all well-known online casino operators have added it to their gaming portfolios, alongside the American variation.
