Roulette tables offer dozens of betting options, from simple Red/Black wagers to complex “Flower” or “Snake” bets covering specific numbers. But how much of the wheel are you actually covering?
Our Roulette Bet Builder allows you to input complex betting patterns to calculate your Total Coverage (%), Volatility, and the mathematical expected value of your spin.
How to Use the Bet Builder
This tool helps you visualize the math behind “systems” like the James Bond strategy or Tier et Tout.
- Wheel Type: Select European (Single Zero – 2.7% Edge) or American (Double Zero – 5.26% Edge). Always play European if you have the choice.
- Input Bets: Enter the amount you wish to place on Outside Bets (Red/Black) or Inside Bets (Single Numbers).
- Analyze: The calculator combines your bets to show:
- Total Bet: Your total investment per spin.
- Expected Value: How much you lose on average per spin.
- Risk Profile: Are you grinding (high coverage, low payout) or gambling (low coverage, high payout)?
The “Cover All” Myth
A common mistake is thinking that covering more numbers increases your profit. While it increases your chance of winning a specific spin, it does not change the House Edge.
Whether you bet $10 on Red or $1 on 18 different numbers, the casino expects to keep exactly 2.7% of your money in the long run. Covering the whole table guarantees a win, but guarantees a net loss because the payout (35:1) is lower than the odds of winning (37 numbers).
Frequently Asked Questions (FAQ)
What is the safest bet in Roulette?
Mathematically, the “safest” bets are the Even Money wagers (Red/Black, Odd/Even, High/Low) on a European table. They have the lowest volatility (you win ~48.6% of the time) and the standard low house edge.
Can I overcome the House Edge with a system?
No. Betting systems like Martingale change the distribution of wins and losses (many small wins vs. one big loss), but they do not alter the mathematical edge of the game. The zero (green slot) ensures the math always favors the house.
