Examining the outside bet

Playing safe is a strategy that suits those with a lesser bankroll. Those with more money to bet with will tend to opt for the inside bets. The system of outside betting requires players to play longer games as they slowly accumulate a profit from the casinos they join.

All these even money bets really carry a 48.65% chance of winning on the European table and not 50%. On the American wheel, the spin will decrease the odds further at 47.37% and this is due to the extra number on the wheel that the ball has to avoid.

The other outside bets that you can place your wagers on include the column and dozen sections. Both covering the opportunity to hedge your bet across 12 numbers, means a third of possible numbers are secured with your chips. Your options online give you the chance to bet on the first, second or the third dozen. The result of this is a probability of 32.43% on the European game and 31.58% in the American version.

  • Street: The street wager performs over three numbers; this could mean rows of numbers. An example of this would be 4, 5 and 6 or if you wanted 19, 20 and 21. This pays at 11 to 1.
  • Corner: The corner bets allow your chips to cover four numbers on the table. Another example would see your money covering 1, 2, 4 and 5. Should this land, your win pays out at 8 to 1.
  • Double Street: The double street bet is all about placing your bet on two rows of numbers, so 6 in total. The winning payout is 5 to 1.
