Most roulette calculators on the web are too simple. They tell you the odds of hitting “Red” or “Number 7,” but they fail to account for how real players actually play.
If you are placing a Multiple Bet Strategy — such as betting on a column, three corners, and hedging with the Zero — you need a tool that can handle the math of combined outcomes. Our Roulette Board Calculator is a true “Bet Builder.” It allows you to simulate placing chips on different parts of the table to calculate your total Table Coverage, potential profit per number, and your overall Expected Value (EV).

How to Use the Roulette Odds Calculator
This tool visualizes the roulette table mathematically. It calculates the “Net Result” for every single pocket on the wheel based on your unique combination of bets.
- Select Wheel Type:
- European (Single Zero): The best odds for the player (House Edge: 2.7%).
- American (Double Zero): The standard in Vegas (House Edge: 5.26%).
- Choose Rules: If you are playing French Roulette, select La Partage. This returns half your even-money stakes if the ball lands on Zero, lowering the house edge to 1.35%.
- Build Your Bets: Use the “Bet Builder” to place chips on the table.
- You can mix Inside Bets (Straight up, Split, Corner) with Outside Bets (Red/Black, Dozens).
- Analyze the Heatmap: The grid at the bottom acts as a Roulette Table Calculator. It shows you exactly how much you win or lose for every specific number. Look for the Green numbers (Profit) versus the Red numbers (Loss).
Real-World Examples: Complex Betting Strategies
Why do you need a coverage calculator? Because combined bets often hide the true risk. Here are two famous strategies analyzed by our tool.
Example 1: The “James Bond” Strategy
This strategy attempts to cover over 60% of the table to generate a flat profit.
- The Setup:
- $140 on High Numbers (19-36).
- $50 on the Line Bet (13-18).
- $10 on Zero (Insurance).
- The Result:
- Coverage: 67.5% (25 numbers covered).
- Profit Map: You win between $80 and $160 if you hit your numbers.
- The Risk: If the ball lands on 1-12, you lose $200 instantly. The calculator visualizes this “Death Zone” clearly.
Example 2: The “Romanosky” Bet
This strategy covers 32 numbers, leaving only 5 losers.
- The Setup: 3 units on Dozen 2, 3 units on Dozen 3, and 1 unit on two separate Corners (covering numbers in Dozen 1).
- The Result:
- Win Probability: 86.5% (European).
- Profit: 1 unit per spin.
- EV: Negative. Even though you win often, the cost of the loss (8 units) outweighs the frequent small wins.
Frequently Asked Questions (FAQ)
What is “Table Coverage” in Roulette?
Table coverage is the percentage of the wheel that results in a win (or at least a return of money). For example, betting on “Red” covers 48.6% of a European wheel. Betting on 35 individual numbers covers 94.5%. High coverage means frequent wins, but usually lower payouts.
Can I use this calculator for Triple Zero Roulette?
Yes. You can toggle the Wheel Type to “Triple Zero.” Note that Triple Zero roulette has a massive house edge of 7.69%, making it one of the worst bets in a casino. We highly recommend sticking to European or Standard American wheels.
Does betting on more numbers increase my Expected Value (EV)?
No. In Roulette, every single bet (except the “Top Line” 5-number bet in American Roulette) has the exact same negative House Edge. Covering more numbers reduces Variance (volatility), but it does not change the mathematical long-term loss rate.
What is the difference between “Profit Probability” and “Win Probability”?
They are often different in multiple bets. You might bet on 20 numbers, meaning you “Hit” 54% of the time. However, if you bet $1 on every number straight up, hitting a number pays $35, but you spent $20. You profit. But if you bet $50 on Red and $1 on Number 2 (Black), and Red hits, you win the Red bet but lose the Number bet. Our calculator shows your Net Result to clarify this.
