Roulette offers a wide array of different betting options, amongst the most simple is the ‘Red or Black’ bet. While it might be very straightforward, it continues to be one of the most popular outside bets placed on a roulette table.

What is a Red or Black Bet in Roulette?

In roulette, a Red or Black bet is a wager that is predicting whether the ball will land on a red or black number on the wheel. A very straight-forward bet, it effectively covers half of the wheel - excluding zero and double zero.

How to Play Roulette Using a Red or Black Bet

To place this bet, you simply put your chips on the corresponding colour on the roulette table. If the ball lands on a number of your chosen colour, you will win.

Is Red or Black Betting Profitable for Roulette?

Using Red or Black betting as part of a broader roulette strategy can be quite successful, with it offering an even-money (1-1) return. The win probabilities attached to this bet are as follows:

  • European Roulette - 48.65%
  • American Roulette - 47.37%

With this in mind, it is important to consider the house advantage on every spin when placing this type of bet. The house advantage for European Roulette is 2.7%, while for American Roulette this figure increases to 5.26% due to the additional number - 00.

So, if you placed a £10 bet on ‘Red’ and ball lands on 18 (red), you would win £10, plus your original £10 wager.
