What Is Roulette?
Roulette is one of the most iconic casino games in the world. The name comes from the French word for "little wheel." The game is simple: a dealer spins a wheel in one direction and a small ball in the opposite direction. The ball eventually lands in one of the numbered pockets on the wheel. Players bet on where they think the ball will land.
Roulette is popular with Nigerian players because it is easy to learn, requires no special skills, and offers a wide range of betting options — from safe outside bets to high-risk straight-up numbers.
The Roulette Wheel and Table
A standard roulette wheel has 37 or 38 numbered pockets, depending on which version you play.
European Roulette
- 37 pockets: numbers 1 through 36, plus a single zero (0)
- House edge: 2.70%
- This is the version most players should look for
American Roulette
- 38 pockets: numbers 1 through 36, plus a single zero (0) and a double zero (00)
- House edge: 5.26%
- The extra double zero nearly doubles the house advantage
For the best odds, always choose European Roulette when it is available. For a full breakdown of the differences — including French roulette with its player-friendly La Partage rule — see our detailed European vs American roulette comparison.

How a Round Works
- Players place chips on the betting layout before the dealer calls "no more bets."
- The dealer spins the wheel and releases the ball.
- The ball lands in a numbered pocket.
- The dealer marks the winning number and clears losing bets.
- Winning bets are paid according to the payout table.
- A new round begins.
In online roulette, the process is automated. You click to place your chips, press spin, and the result is determined by a Random Number Generator (RNG) or a live-streamed physical wheel.
RTP and House Edge Explained
RTP stands for Return to Player — the percentage of all wagered money that a game pays back to players over time.
- European Roulette RTP: 97.30%
- American Roulette RTP: 94.74%
This does not mean you will get back 97.30% of your money every session. RTP is a long-term statistical average calculated over millions of spins. In a single session, anything can happen. Use our RTP and house edge calculator to see the numbers for yourself.
Smart Play Tips for Beginners
Set a Budget Before You Start
Decide how much you are willing to spend before you sit down. Treat it as entertainment money, not an investment. Never chase losses.
Start with Outside Bets
Red/Black, Odd/Even, and Low/High bets win nearly half the time. They are a good way to learn the rhythm of the game without burning through your bankroll quickly.
Avoid Betting Systems That Promise Guaranteed Wins
Systems like Martingale (doubling your bet after each loss) can lead to very large losses very quickly. No betting system changes the house edge. The math of roulette does not change based on what happened in previous spins — each spin is independent.
Play European Roulette Whenever Possible
The single zero format gives you significantly better odds than the American double zero version. This is the single most impactful choice you can make as a roulette player.
Know When to Walk Away
Set a win target and a loss limit before you play. If you hit either, stop. The game will still be there tomorrow.
Live Roulette vs. RNG Roulette
Live Roulette
- Real dealer, real wheel, streamed in real time
- Social atmosphere with chat features
- Slower pace — good for beginners learning the game
RNG Roulette
- Computer-generated results using a certified Random Number Generator
- Faster pace — more spins per hour
- Usually lower minimum bets
Both formats are fair when offered by a licensed casino. Choose based on whether you prefer speed or atmosphere.
Common Beginner Mistakes to Avoid
Confusing Inside and Outside Bets
Inside bets pay more but win less often. Outside bets pay less but win more often. As a beginner, build your confidence with outside bets first.
Believing in "Hot" or "Cold" Numbers
Each spin of the roulette wheel is completely independent. A number that has appeared five times in a row is no more or less likely to appear on the next spin than any other number. The wheel has no memory.
Playing Without Checking the Rules
Different roulette tables have different minimum and maximum bets. Some may have special rules like "La Partage" or "En Prison" that affect the house edge on even-money bets. Always check the table rules before you start playing.
