How It Works

Roulette offers various bet types with different odds, payouts, and house edges. Understanding these helps you make informed betting decisions.

How Roulette Odds Are Calculated:

Probability = Number of Winning Outcomes / Total Number of Outcomes

Payout = Stake × (36 / Number of Covered Numbers - 1)

House Edge = (Probability × Payout) - 1

Example:

If you bet $100 on a straight up bet (single number) in European roulette:

  • Probability = 1 / 37 = 2.70%
  • Payout = $100 × 35 = $3,500
  • House Edge = 2.70% (European) or 5.26% (American)
