The roulette wheel consists of a rotating plate with dividers around the edge that rotates around the bottom of the bowl. The ball is rotated outside the bowl until the ball and wheel finally rest with the ball in one division.

The distributions around the wheel are numbered 1 to 36 as a seemingly random pattern and alternate in red and black. In addition, there is a green split numbered 0. Only American tables have another extra green split marked with 00, and for the most part this makes the American version of roulette an economically worse offer than the European game.

Before throwing the ball, people bet on which number will appear by placing chips on the betting mat. The exact location of the chips indicates the bet. Roulette is a game of French origin, and on the traditional table, French terms for betting areas are still used in English-speaking areas. However, most U.S. tables use English terms and a slightly different matte style.

Roulette bets

  • The great interest in roulette is due to how many different bets can be made and the odds associated with them. The basic bets are the same for all forms of modern roulette. Below is a list of all available bets, classified according to the odds associated with the bet (both English and French terms are listed):
  • Flat
  • Red / Rouge: red number
  • Black / Noir: black number
  • Even / pair: even number
  • Odd / Impaired: Odd number
  • Low Bet / Manque: Numbers 1-18 (Manque is a French “failed” and is used because the ball has not passed 18)
  • High Stake / Passe: Numbers 19-36 (Passe is named because it has “passed” the center)


  • The first dozen / Premiere douzaine: numbers 1-12 (on a French-style rug, a square marked 12P)
  • Middle dozen / Moyenne douzaine: numbers 13-24 (on a French-style rug square marked 12M)
  • Last Dozen / Dernier douzaine: numbers 25-36 (on a French-style rug, a square marked 12D)
  • Column Batch / Colonne: 12 digit column (special square at the end of one of the three twelve digit columns)
  • Longer odds
  • 5-1 – Line Bet / Sixain: 6 digits (Place a bet at the intersection of the edges of two three-line lines to bet on these two lines)
  • 8-1 – Corner Bet / Carre: 4 digits (Place a bet at the intersection of a four digit square)
  • 11 – 1 – Street bet / Carre simple or Transversale: 3-digit line (halfway over the line that forms the end of the three-digit line to be bet)
  • 17: 1: Split bet / En Chaval: pair of numbers (Place a bet over the line by dividing the two numbers to bet
  • 35 out of 1: Straight up / En plein: one number (Place a bet in the box that shows that number. You can bet from zero)
  • Bets on six or less numbers are called “internal bets”. Bets on 12 or more numbers are called “outside bets”.

European roulette rules

Assuming all possible bets are understood, roulette is essentially a trivially simple game. For each round, when all bets have been made with colored chips to distinguish each player, the croupier interrupts the betting, spins the wheel and throws the ball in the opposite direction. When the ball stops at one starting point, the croupier announces the result, collects all lost bets and pays the winner’s winnings.

Some casinos and houses play other optional rules. Both the La Partage and En Prison roulette rules halve the casino’s interest in money. If you play at home, decide from the beginning which of the following rules you want to play.

En Prison rule

  • This is a roulette rule that can only be applied to flat money bets. When zero rises, the player has two options:
  • Redeem half the bet and lose the other half.
  • Leave a bet (in prison = in prison) for the next roulette spin if you want to play all or nothing. If the next round is again zero or does not match the captured bet, the entire bet will be forfeited. Otherwise, the player’s money will be refunded if the result of the next round matches the bet.
  • La Partage rule

The la partage roulette rule is similar to the prison rule, only in this case the player has no choice when a zero appears and simply loses half the bet.

Maximum and minimum bet

Casinos usually place a maximum and minimum bet on a roulette table, and this is sometimes done for leisure play as well. Typically, for each wheel spin, if the total number of internal stakes of a player must exceed the minimum bet. The maximum bet listed usually only shows the maximum allowable bet for a single “straight” bet. The maximum bets for other types of bets increase proportionally, e.g.

North American Roulette Rules

In North America and the Caribbean, roulette wheels have a double zero, and all bets (except for a direct bet on the selected zero) will be lost when either zero rises. The result is significantly worse odds per pound and an increase in casino cut. Probably because roulette is less popular in this area than in the rest of the world.

The rules are the same as in European Roulette above, except that a double zero works in the same way as a single zero result.

Some American casinos allow an additional bet called a “basket bet,” which is wagered by placing chips in the same way as a line bet outside the dividing line between the zero line and line 1, 2, and 3. This bet usually costs 6-1, which gives it odds worse than any other roulette bet.

Old original roulette game

In the original French roulette, numbers 1 to 36 had zero and “double zero”. Zero was red in color and was also counted as “pair” and “manicure”; the double zero was black and was also counted as “Damage” and “Pass”.

If the ball fell into one of the two zero divisions, the bank takes all the lost bets, but if the bet was matched to be Pair, Impair, Rouge, Noir, Passe or Manque, the bet was in jail until the next wheel spin instead of winning. In that subsequent turn, the bet was either lost or if the ball was re-bet, the bet was only returned to the player without a win.
