Outside Bet

Outside bets in roulette are wagers placed on the outer sections of the table layout, covering larger groups of numbers. They include even-money bets (red/black, odd/even, high/low), dozen bets (1-12, 13-24, 25-36), and column bets. Outside bets offer lower payouts but significantly higher probabilities of winning.

Even-money bets pay 1 to 1 and cover 18 of the 37 numbers on a European wheel (48.6% probability). Dozen and column bets pay 2 to 1 and cover 12 of 37 numbers (32.4% probability). All outside bets carry the same 2.70% house edge in European roulette. The la partage and en prison rules, when available, reduce the house edge on even-money bets to 1.35%.

Outside bets are popular with conservative roulette players because they produce frequent wins and extend playing time. Betting $10 on red and winning pays $10, while the same $10 on a single number pays $350 but wins far less often. For players who value steady entertainment over volatile swings, outside bets are the preferred approach.

A common misconception is that combining outside bets can create a profitable system. Betting on both red and a column, or covering two dozens, changes the win frequency and payout pattern but does not alter the mathematical house edge. Every combination of standard roulette bets has the same 2.70% expected loss per dollar wagered on a European wheel.
