In roulette, a player's betting options are categorized into inside or outside wagers.
Single numbers: Players may wager on a single number space, including 1-36, 0 and 00. If that number is rolled, the player wins.
Split numbers: A player may also place a split wager, or a bet that covers two adjacent numbers on the grid. For example, a player may bet on 19 and 20, or 20 and 23. If the spin lands on either number in a split bet, the player wins.
Corner bets: Players may bet on four adjacent numbers by placing their chips in the corner of the desired grid spaces. For example, a corner bet may be placed on 11, 12, 14 and 15. The player wins a corner bet if the spin lands on any of the four numbers.
Outside wagers include:
Columns: Players may place bets on which column the mark will land in following the spin. By placing their chips in the space below a column of numbers, the player wagers that the spin will land on one of those numbers.
Colors: Players may bet on which color they believe the spin will land on, either red or black. The player wins if the spin lands on any number in that color.
Even or odd: Players may wager on whether the spin will land on an odd number or an even number. If the spin lands on 0 or 00, players who bet on even or odd lose.
High or low: A high or low wager allows the player to select which number range they believe the next spin will fall within. The ranges are 1-18 (low) or 19-36 (high).
Dozen: Like a high or low bet, the dozens bet allows players to wager on a range of numbers. In the dozens bet, players may select the first 12 (1-12), the second 12 (13-24), or the third 12 (25-36).
Additional bets are available. Please refer to the table layout, the dealer or the table supervisor for more information. Winning bets are paid out based on pay tables set by the casino.
