How Roulette Works
Roulette is a casino game where players bet on where a ball will land after it's spun around a wheel. The wheel has numbered pockets, and players can bet on a single number (straight up bet), groups of numbers (split, street, corner, etc.), or colors (red or black).
The house edge in roulette is built into the game design. For American roulette, the house edge is 5.26% for a straight up bet, while European roulette has a house edge of 2.70% for the same bet.
Calculating Expected Value
The expected value (EV) of a bet is calculated by multiplying the probability of winning by the amount you win, and subtracting the probability of losing by the amount you lose. The formula for expected value is:
For example, a straight up bet in American roulette has a probability of winning of 1/38 (2.63%) and pays 35:1. The expected value of a $10 bet is:
This means you can expect to lose about $0.53 per $10 bet on average.
Bankroll Management
Managing your bankroll is crucial when playing roulette. A common rule is to bet no more than 1-5% of your total bankroll on any single bet. This helps you avoid going broke too quickly and gives you a chance to win back some of your losses.
For example, if you have a $1,000 bankroll, you might bet between $10 and $50 per spin. This calculator can help you determine how many spins you can expect to play before going broke based on your bankroll and bet size.
Example Calculation
Let's say you have a $1,000 bankroll and you want to make a straight up bet of $10 per spin. Using the calculator, you can see that:
- Your expected value per bet is -$0.53.
- You can expect to play about 1,887 spins before going broke.
- Your total expected loss is about $943.50.
This means that over time, you can expect to lose about $943.50 for every $1,000 you bet.
