Online Roulette Glossary

American Roulette – This has a roulette wheel that has thirty eight pockets, one of which is the double zero. The American variant has a higher house edge than a European roulette wheel.

Choppy Game – A game where the players and the house are going back and forth, taking turns winning and losing.

Column Bet – When a player bets on one of the three, twelve-number columns on the roulette layout.

Corner Bet – When a player makes a wager on four bets by placing their chips on the corner of the adjacent numbers. This is also known as Carré in French.

Croupier – The casino employee that operates the roulette table. They are often mistakenly referred to as a roulette dealer.

Dozen Bet – When a player bets on one of the three consecutive dozens on the table.

En Prison – An advantageous rule that gives you a second chance to get your outside bets bet after losing to a “0” or a “00”. Not offered in most modern casinos.

European Roulette – A roulette wheel with thirty seven pockets; advantageous when compared to the American roulette wheel, because it does not have a “00” pocket.

House Edge – The percentage advantage the house has over the players for any given bet or game. The lower this number is, the closer to fair the game will be.

High Bet – When you place a bet on any of the numbers from nineteen to thirty six.

Inside Bet – A bet placed on any of the specific numbers. These bets are named for their location on the inside of the roulette table’s layout.

Low Bet – When a player bets on the first eight numbers.

Outside Bet – Even money wagers that are named for their location on the outside of the roulette table’s layout. These include bets like black/red, even/odd, and high/low. These are the only bets that benefit from the inclusion of En Prison rules.

Quarter Bet – Betting on four numbers with a single wager; very similar to a corner bet.

Roulette Layout – The numbered and colored grid where players place their chips to make bets.

Roulette Table – Includes the roulette layout as well as the roulette wheel.

Roulette Wheel – The only moving part on a roulette table, this is the mechanism that determines which bets win and which bets lose. It typically contains either thirty seven or thirty eight distinct pockets.

Straight Bet – This is the iconic bet on a single number. While very unlikely to win, the house offers a 35:1 payout, making it potentially quite lucrative. Regardless of these extremes, it still has the same house edge as most roulette wagers.

Street Bet – A roulette wager which is placed on three numbers.

Wheel Clocking – This is the act of recording the history of a roulette wheel and looking for patterns. This is done in hopes of taking advantage of an imperfection in the wheel which may make some numbers more likely to appear. While hotly debated in a live casino setting, this will not function in an online casino that depends on a random number generator.
