Inside bets

  • Straight-up: a single number bet. The chip is placed entirely on the middle of a number square.
  • Split: a bet on two adjoining numbers, either on the vertical or horizontal (as in 14-17 or 8-9). The chip is placed on the line between these numbers.
  • Street: a bet on three numbers on a single horizontal line. The chip is placed on the edge of the line of a number at the end of the line (either the left or the right, depending on the layout).
  • Corner (or square): a bet on four numbers in a square layout (as in 11-12-14-15). The chip is placed at the horizontal and vertical intersection of the lines between the four numbers.
  • Six Line (or Double Street): a bet on two adjoining streets, with the chip placed at the corresponding intersection, as if in between where two street bets would be placed.
  • Trio: a bet on the intersecting point between 0, 1 and 2, or 0, 2 and 3 (single-zero layout only).
  • Basket: a bet on 0, 1, and 2; 0, 00, and 2; or 00, 2, and 3 (double-zero layout only). The chip is placed at the intersection of the three desired numbers.
  • Top Line: a bet on 0, 00, 1, 2, and 3 (double-zero layout only). The chip is placed either at the corner of 0 and 1, or the corner of 00 and 3.

Outside bets

Outside bets typically have smaller payouts with better odds at winning.

  • 1 to 18: a bet on one of the first low eighteen numbers coming up.
  • 19 to 36: a bet on one of the last high eighteen numbers coming up.
  • Red or Black: a bet on which color the roulette wheel will show.
  • Even or Odd: a bet on an even or odd number.
  • Dozen Bets: a bet on the first (1-12), second (13-24), or third group (25-36) of twelve numbers.
  • Column Bets: a bet on all 12 numbers on any of the three vertical lines (such as 1-4-7-10 on down to 34). The chip is placed on the space below the final number in this string.
  • Snake Bet is essentially a special “Dozen Bet” consisting of a bet of the following numbers: 1,5,9,12,14,16,19,23,27,30,32 & 34. Some gambling experts consider it a “sucker bet” as they claim that the player has to bet a unit on each of those numbers. However, some casinos which allow the “Snake Bet” (not all casinos do) allow the table minimum to be bet on “The Snake” by placing the bet on the lower corner of the “34” spot which touches the “19-36” even money bet.

In the UK all bets have the same play to payout ratio, for instance putting one chip on each number 1-12 will yield the same outcome as 12 chips on the first dozen (assuming the original stake is removed). The exception is the very outside bets (red/black, odd/even, low numbers/high numbers) when zero is the result only half of the original stake is captured by the dealer !
