Classification of bets in roulette

Roulette casino game introduces a great variety of betting options. Betting is actually the main point of roulette rules as far as to win at roulette it is important to make a bet on numbers that you think might win. It is important to get acquainted with all types of bets in roulette in order not to get confused among all betting options. Our roulette guide will provide you with the basic classification of bets in roulette.

Inside and outside bets

The most common bets in roulette are inside and outside bets. They correspond to the two sections of the roulette table layout - inside and outside. To make inside or outside bets in roulette, the player is supposed to place his or her colored chips on certain numbers, on borderlines combining groups of numbers or on betting options in the outside section of the table layout.

The payouts for inside and outside bets are the same in European and American roulette, but due to the presence of the second zero pocket on the American roulette wheel the betting probabilities are different in European and American roulette game variants.

Inside bets are placed in the inside section of the table layout (number grid). These are the bets on a particular number or a group of numbers depending on their vicinity on the layout.

  • Straight bets are bets on a single number that pay 35 to 1 (even though the true odds are 36 to 1, the presence of zero reduces the odds at roulette). These are the riskiest bets of all as the probabilities of hitting a single number are very low.
  • Split bets on 2 neighboring numbers pay 17 to 1.
  • Street bets on 3 numbers pay 11 to 1.
  • Corner bets on 4 numbers pay 8 to 1.
  • Line bets on 6 numbers pay 5 to 1.

Outside bets are placed in the outside section of the table layout and are made on larger groups of numbers:

  • Red-Black, Odd-Even and Low-High (numbers 1 to 18 and 19 to 36) bets are bets on even money and are paid out at 1 to 1. Even as they pay less, these are the most likely bets in roulette.
  • Column and Dozen bets pay 2 to 1. Columns are vertical lines of numbers on the layout, while Dozens represent 1st, 2ndand 3rd 12 numbers as arranged on the layout.

American roulette rules allow additional five number bet - 1, 2, 3 and '0' and '00'. It is better to avoid this bet as it has the highest house edge in roulette - about 7.9%.

Call or announced bets

Available in French roulette in the first place, call bets (or announced bets) are, as the name suggests, called out by the player and followed by his or her placing money on the table before the results of the spin are made known:

  • Voisins du zero (also known as the "neighbors of the zero")
  • Tiers or The Third ones
  • Jeu ero or zero game
  • Orphelins or orphans
  • Finales en Plein
  • Finales a Cheval
  • XX and its neighbors

Roulette call bets depend on the arrangement of numbers specific for European and French roulette and are unavailable at American roulette with its balanced number sequences.

Improved or complex bets

In his book Roulette Odds and Profits: The Mathematics of Complex Bets Catalin Barboianu proves that special complex or improved bets in roulette may improve the player's odds. Compared to simple bets made on certain numbers or groups of numbers, complex bets combine two different kinds of the former. E.g. one may bet on Black or Red and any number(s) of opposite color, etc.
