As with any casino game, roulette has its own unique language to describe wagers and the different parts of the roulette table and wheel.  This is a roulette glossary that translates some of the most common terms you will hear around the roulette table into plain English.

Roulette Glossary

  • American Roulette – The version of Roulette most commonly found in the United States.  American roulette uses 38 different numbers (1 – 36, 0, and 00) as opposed to the 37 numbers used on the European Roulette Wheel.
  • Black Bet – A wager that the winning number will be black.  A winning black bet pays 1 to 1 odds.
  • Column Bet – All of the numbers on the roulette table are arranged into 3 columns (except for the 0 or 00).  A column bet is a wager that the next winning number will be in a particular column.  This bet is made by placing your wager in the square at the end of the column you wish to bet on.  A winning column bet pays 2 to 1.
  • Corner Bet – A bet placed on 4 numbers at once.  This bet can only be placed on numbers that are all touch each other.  It is called a corner bet because the player’s wager is placed on the corner that connects 4 adjoining numbers on the roulette table.  A winning corner bet pays 8 to 1.
  • Croupier – The casino staff person who is in charge of the roulette table.  He will pay out winning bets, take away losing bets, and manage the roulette wheel.
  • Dozen Bet – A bet placed on a group of 12 sequential numbers at once. Bets can be placed on the numbers 1-12, 13-24, or 25-36.  A winning dozen bet pays 2 to one.  This bet is very similar to the column bet, but is on a different set of numbers.
  • Double-Zero – Used in American Roulette, the double zero is an extra square added to the board next to the 0.
  • European Roulette – A popular version of Roulette that is played mainly in Europe.  Unlike American Roulette, European Roulette uses only one 0 square instead of a 0 and a 00 square.
  • Even Bet – A wager that the next winning number will be even as opposed to odd, 0, or 00.  A winning even bet pays 1 to 1 odds.
  • Five Number Bet – A wager that one of the first 5 numbers on the wheel- 0, 00, 1, 2, and 3- will be the winning number.  This bet is only available in American Roulette.  A winning five number bet pays 6 to 1 odds.
  • High Bet – A bet that the winning number will be between 19 and 36.  A winning high bet pays 1 to 1 odds.
  • Inside Bet – Any wager on one or more numbers found on the table.  The alternative to an inside bet is an outside bet.
  • Low Bet– A wager that the winning number will be between 1 and 18.  This is similar to a high bet except the low bet is on the other half of the numbers.  A winning low bet pays 1 to 1.
  • Odd Bet – A wager that the winning number will be odd.  This is exactly like an even bet, except on the odd numbers.  A winning odd bet pays 1 to 1.
  • Outside Bet – Any wager that is not placed directly on the numbers themselves, but are played instead on the bets available on the outside of the table.  Examples include a black bet, red bet, even bet, odd bet, column bet, etc.
  • Red Bet – A wager that the winning number will be red.  A winning red bet pays 1 to 1 odds.
  • Six-Number Bet – A bet on 6 adjacent numbers on the roulette table.  A 6 number bet is made by placing a chip on the outside corner connecting two rows of numbers.  A winning 6 number bet pays 5 to 1 odds.
  • Split Bet – A wager on any two adjacent numbers on the roulette table.  A split bet is made by placing a chip on the line that connects two adjacent numbers on the roulette table.  A winning split bet pays 17 to 1 odds.
  • Straight Bet – A wager on any single number on the roulette table.  This is one of the most common wagers played in roulette.  A winning straight bet pays 35 to 1 odds.
  • Straight Up Bet – The same as a straight bet (see above)
  • Trio Bet – A wager on any row of numbers found on the roulette table.  A trio bet is made by placing a chip on the outside edge of any row of numbers on the roulette table.  A winning trio bet pays 11 to 1.
  • Zero – The number 0 on the roulette wheel and table.
