Roulette is a gambling game in which players bet on a ball landing in one of several numbered holes in a wheel. The resulting number is called the “number of the hole” and is used to determine how many chips the player must place in order to complete their wager.
The wheel is a solid wooden disk with metal partitions (known as frets) around its rim. The numbers on the roulette wheel are arranged in a variety of ways and are nonconsecutively numbered from 1 to 36. The numbers on the European-style roulette wheel are alternating red and black; on the American-style wheel, there are two green compartments that carry the number 0 and 00.
When the croupier spins the wheel, the ball falls into one of the pockets and settles on a specific number. If you placed a bet on that number, you win the bet.
There are two main types of bets in roulette: inside and outside. The inside bets are bets on a particular pocket or group of pockets, while the outside bets are bets on other areas of the board. The payout odds for the inside bets vary depending on how many pockets the ball lands in, while the outside bets are based on a probability formula.
Bets on a Single Number
The single-number bet is the most common type of roulette bet and is usually made by placing a chip at the corresponding spot on the table layout. This bet pays a small amount of money, but it is one of the more exciting and rewarding bets to make.
The split bet is a unique betting option that allows players to place chips on a line of two adjacent numbers on the table layout. This bet pays 17-1 if any of the two numbers wins.
The square bet is another unusual and unique betting option that lets players place a bet on four numbers on the table. This bet is a simple proposition and is often called the corner bet.
Trio Bet/Side Bet
The trio bet is a type of side bet that lets players place a single chip on any three consecutive numbers on the table. This bet is popular in European casinos and can pay out well.
