Roullete is a popular game of chance played at casinos around the world. It was invented in the late 1700s and has been widely adapted to include online and land-based versions with new variations emerging regularly as a result of advances in technology.

Roulette is a casino game of chance played at a table marked off with numbers from 1 to 36, one or two zeros, and several other sections affording the players a variety of betting opportunities. In the centre of the table is a revolving, dishlike device (the roulette wheel) into which the ball is dropped.

The roulette wheel consists of a wooden disk with metal partitions or canoes, which separate the compartments into which the ball falls. The divisions are numbered from 1 to 36, and alternate red and black. On European-style wheels a 37th compartment, painted green, carries the sign 0.

There are six types of bets in roulette: inside bets, outside bets, corner bets, basket bets, square bets, and line bets. The payout odds for each type of bet vary according to the position on the board it is placed and the probability of the number being hit.

Inside Bets: These bets are made on the numbers on the inner part of the roulette table, which is closer to the center. They have a lower probability of winning but higher payouts.

Outside Bets: These bets are made in other parts of the roulette table, which are further away from the center. They have a lower probability than inside bets but higher payouts.

Corner Bets: These bets are placed on a square of four numbers, and can pay up to 8-1 if any of the four numbers win.

Basket Bets: These bets are placed in an area that divides the two rows of the zero row from the three rows containing numbers 1, 2 and 3. They can pay up to 5-1 if any of the four numbers on this section win.

The rules of roulette are relatively simple and straightforward. However, there are subtle differences between the American, European and French varieties of the game that a player needs to understand before placing their bets. For instance, the French version of the game has la partage – a rule that says that if a bet wins and lands on zero, half the stake is returned to the player. The house edge is higher in the French version than in the American, but it is still much lower than in craps.
