Roulette: A Simple Guide to Rules and Odds
Roulette is one of the simplest and most popular casino games—and for good reason. The basics are easy to grasp, with straightforward rules and fixed odds that don’t change based on how you bet. There’s no need to master complicated strategies, which is what makes roulette accessible and enjoyable for both beginners and seasoned players alike. Still, whether you’re new or just need a refresher, understanding the fundamentals is key.
How to Play Roulette: The Basics
Roulette is played with a wheel and a betting board. The board displays numbers 1 through 36, which alternate between red and black, plus a green 0.
Players place their chips on specific numbers or groups of numbers. Bets can be made on:
– Individual numbers
– Red or black
– Odd or even
– Rows or columns
– Larger groups like dozens or halves of the board
When the dealer announces “place your bets,” players have a limited window to put their chips on the table. Once the dealer says “no more bets,” the ball is spun inside the roulette wheel, which has numbered pockets corresponding to the betting board. The ball eventually lands in one of these pockets—whichever number it lands on determines the outcome of the round.
Winning bets are paid out according to the odds of the wager, while losing bets are collected by the house. Every roulette table comes with minimum and maximum betting limits, so make sure you’re at a table that matches your budget and risk comfort.
Roulette vs. Other Casino Games
If you compare roulette to games like blackjack or poker, the differences are pretty clear.
In blackjack, while the rules are still fairly simple, there’s a strategic layer that can significantly reduce the house edge if applied correctly. Knowing whether to hit or stand based on the dealer’s visible card is an essential part of the game.
Poker, especially popular variations like Texas Hold’em, is even more strategy-driven. While luck plays a role, poker pits players against each other, meaning factors like bluffing, reading opponents, and betting strategy can have a major impact. Winning doesn’t always depend on having the best cards—it’s just as much about outthinking your opponents.
Roulette, on the other hand, is more like a game of pure chance. All bets, regardless of type, have a consistent house edge (more on that below), and there’s no real strategy that can shift the odds in your favor. That simplicity is part of roulette’s charm—you can start playing immediately and simply focus on having fun.
Odds and House Edge in Roulette
Let’s look at how the house edge and odds work in roulette.
Take the common red or black bet. This pays out at 1:1—if you wager $1, you win $1 plus your original bet. However, because of the green 0 on the wheel, it’s not quite a 50/50 proposition. Instead, there’s a 48.65% chance of landing on red or black in European roulette, which has 37 total numbers (1 to 36, plus 0).
If you choose to bet on a single number, the payout is 35:1. That means a $1 bet wins $35, plus your original dollar returned. While this seems like a good return, the odds of winning that bet are only 1 in 37—again, due to the extra green 0.
Online roulette uses random number generators (RNGs) to ensure fairness and replicate the wheel’s odds. Whether you’re playing in a real casino or online, these odds remain the same.
In European roulette, the house edge is 2.7%, meaning the casino expects to keep $2.70 for every $100 wagered over time. This edge remains consistent across all types of bets.
European vs. American Roulette
This article has focused on European roulette, which features a single green 0 and carries a 2.7% house edge.
American roulette adds an extra green 00 slot, bringing the total to 38 numbers. However, payouts remain the same—35:1 on single numbers, for example. This reduces the player’s odds and increases the house edge significantly to 5.26%.
When given the choice, it’s smarter to play European roulette due to the lower house edge and better odds overall.
Final Thoughts
Roulette is a game that blends excitement with simplicity. There’s no need to memorize complex strategies or worry about making the perfect move. Instead, it’s about understanding the basic rules, knowing your odds, and playing responsibly within your budget. Whether you’re at a casino or playing online, roulette remains a timeless classic that’s easy to enjoy.
