About Roulette Betting

Roulette offers a variety of betting options with different odds and payouts. European roulette (single zero) has a lower house edge than American roulette (double zero).

Inside Bets
  • Straight Up: Betting on a single number (35:1 payout)
  • Split: Betting on two adjacent numbers (17:1 payout)
  • Street: Betting on three numbers in a row (11:1 payout)
  • Corner: Betting on four numbers forming a square (8:1 payout)
  • Basket: Betting on 0, 00, 1, 2, 3 (American roulette only, 6:1 payout)
  • Double Street: Betting on six numbers from two adjacent rows (5:1 payout)
Outside Bets
  • Column: Betting on one of the three columns of twelve numbers (2:1 payout)
  • Dozen: Betting on 1-12, 13-24, or 25-36 (2:1 payout)
  • Red/Black: Betting on all red or all black numbers (1:1 payout)
  • Even/Odd: Betting on all even or all odd numbers (1:1 payout)
  • High/Low: Betting on 1-18 (low) or 19-36 (high) (1:1 payout)
House Edge

The house edge is the mathematical advantage the casino has over players:

  • European Roulette: 2.70% (1/37)
  • American Roulette: 5.26% (2/38)

The house edge is the primary reason why roulette players will lose money over the long run.

What Is the Roulette Odds Calculator?

The Roulette Odds Calculator is a practical tool for quickly estimating the outcomes of various roulette bets. Whether you’re experimenting with Inside Bets like Straight Up and Corner, or Outside Bets such as Red/Black or Dozen, this tool helps you understand potential payouts, win probabilities, and the house edge.

It supports both American (double zero) and European (single zero) roulette types, offering flexibility for players who enjoy different versions of the game.

Key Benefits

  • Instant Results: See potential payout, profit, and expected value based on your bet.
  • Visual Breakdown: Get clear stats on probability, house edge, and odds for each bet type.
  • Supports All Bet Types: Includes both inside and outside bets with contextual explanations.
  • Beginner-Friendly: Ideal for learning how roulette payouts and chances work in real-time.

Formula Breakdown

Potential Payout:
\( \text{Payout} = \text{Bet Amount} + (\text{Bet Amount} \times \text{Payout Multiplier}) \)

Winning Probability:
\( \text{Probability} = \frac{\text{Winning Numbers}}{\text{Total Numbers on Wheel}} \)

House Edge:
\( \text{House Edge} = (\text{Fair Multiplier} - \text{Actual Multiplier}) \times \text{Win Probability} \times 100 \)

Expected Value:
\( \text{EV} = \text{Bet Amount} \times [(\text{Win Probability} \times \text{Payout Multiplier}) - (1 - \text{Win Probability})] \)

Why This Tool is Useful

This calculator is valuable for roulette players looking to improve decision-making at the table. It provides clarity on:

  • Which bets offer higher probability versus risk
  • How payouts are structured for different bet types
  • How expected value can influence your strategy
  • Understanding how the house edge affects long-term play

Final Thoughts

Whether you’re a curious player, a beginner, or someone refining your strategy, the Roulette Odds Calculator brings clarity to your choices.
