Play Online Roulette for Free or Real Money | 2021
Roulette is one of the easiest casino games to play in the world. You choose a number, place your bet, watch the wheel spin, and wait for the results. Playing online roulette for real money is no different than playing at a brick and mortar casino.
The only difference between the two is your options. You have an abundance of options as to how you want to play. These options range from real money to free games, mobile to PC & Mac games as well as virtual vs. live dealer craps. Our roulette guide covers this and more.

How to Play Roulette
Roulette is an easy game to learn. Follow the tips below and you’ll be playing roulette in no time. Whether you play in a land-based or online casino, find European Roulette and play it if allowed. In a land-based casino, look at the wheel to tell the games apart. If you see a 00 space, the game is American style and you should move on.
Once you find the roulette game you want to play, place bets before the next spin of the wheel. Players can bet on single numbers or up to 18 numbers, so you have a wide range of bets. Follow the roulette betting guide below to place bets correctly on the layout. Once this is done, the croupier does the rest.
Types of Roulette Games and Rules
Roulette has three main variations, but it has many alternate versions and house rules. This section covers the major versions of roulette and the rules you’re most likely to find in casinos.
- European Roulette: European Roulette appeared in Monte Carlo in the 19th century. It has 37 numbered slots and is called single-zero roulette. The house edge is 2.70% and the game most online roulette players should choose.
- American Roulette: American Roulette is played in Las Vegas (North America) and is the game most similar to the original roulette of the 17th century. It has 38 numbered slots and is called double-zero roulette. Because it has an extra zero pocket, the house edge is 5.26%. Don’t play this game if you have the option.
- French Roulette: This is the version with announced bets and the French-sounding wagers. It has 37 slots and a house edge of 2.70%. High rollers love this game because one bet (the full/maximum bet) is like 12 bets in one, allowing you to max out bet limits.
- En Prison Rules: A variant rule used in European Roulette (mostly) that places your bet “in prison” if the ball lands on the zero. If you win the next spin, you win the imprisoned bet. If you lose, then you lose both bets. Lowers the house edge to 1.35%, comparable to craps.
- La Partage Rules: Literally meaning “of the parts”, this house rule means you only lose half your bet when the ball lands on zero. Like En Prison rules, this lowers the house edge of European Roulette to 1.35%.

Roulette Odds
The historical difference between American style roulette, with its two zero slots, and the European style that uses just one 0, has had a big impact on casino gambler’s choice of games. The difference in odds between the 37 number spots on European-style roulette wheels and the 38 slots available on American roulette wheels is significant.
Roulette on a European-style wheel gives you 36:1 odds of winning on a single-number bet, and American style wheels offer 37:1 odds on the same bet. Playing on a European roulette wheel offers a house edge almost half of what American roulette offers. Single-number bets on European wheels give the house a 2.6% edge, while the same bets on American wheels offer a 5.27% edge to the casino.
Roulette is a fun game because of the visual aspect of the silver ball rattling around in the wheel. You don’t have to play European style wheels to have fun or win at roulette, but your chances of winning improve if you avoid American roulette.

Online Roulette for Real Money FAQ
Most bets on the roulette layout have the same odds, even if the payouts are much different. European Roulette bets and French Roulette bets have a 2.70% house edge, assuming no house rules are in effect. American Roulette bets have a 5.26% house edge, assuming the same.
One bet in American Roulette is much worse – the box bet, a five-number bet that includes the 0, 00, 1, 2 and 3. Never make that wager, because it’s a sucker bet. Readers might wonder how bets can have the same odds if they have different payouts, but it’s because the probability of hitting a bet with a 35:1 payout is much lower.
“En prison” is a house rule that means “imprisonment” in French. It’s a common house rule in some European casinos for European Roulette. When the rule is in effect, any time the ball lands in the zero pocket, it’s not an automatic loss for the player. Instead, the bet on that spin goes into prison and you make a new bet. The imprisoned bet rides on the next result, thus giving you another chance that you won’t lose the bet.
If you win the next spin, then you receive half of the original wager back. If you lose, then you lose the entire bet. En Prison rules lower the house edge to 1.35% – comparable with the best bet in craps. As a matter of roulette strategy, always check if a casino has this house rule and play En Prison Roulette if possible.
“La partage” means “of the parts” in French – or in this case, literally one-half. It’s similar to the “en prison” rule, though it cuts to the chase. If the ball lands on the zero pocket, then you lose only half your wager – the other half is returned to you immediately. La Partage Roulette also lowers the house edge to 1.35% and is a rule players seek out, whether they’re playing land-based, online or mobile roulette.
By New Jersey law, Atlantic City casinos must offer a form of the “la partage” rule for their roulette games. Since it’s American Roulette, the house edge is halved to 2.63% – slightly better than traditional European Roulette. The law only applies to the outside bets, so if you wager any of the inside bets, the house edge is double what it otherwise is.
European Roulette often has much better odds for the player than online slots, online scratch cards and Keno games. For that reason, slots, scratch cards and Keno often count 100% toward the wagering requirement. Table games like roulette just as often only count a lower percentage toward the rollover.
It depends on the type of roulette you prefer. BoVegas is our pick if you prefer French Roulette — you’ll receive a $6000 welcome bonus on your first deposit. Slots.lv, Bovada, Ignition, and Cafe Casino feature live blackjack, plus several variations of online blackjack.
Roaring 21 offers a $10,000 bonus, but you’ll have to satisfy yourself with online roulette — it doesn’t have live roulette yet.
