How to Choose the Best Online Roulette Bonus

With so many new casinos launching all the time, finding one that’s safe, fair, and great for roulette can feel like a chore. That’s why our experts have already done the heavy lifting for you. Want to skip the research? Our team has tested, compared, and shortlisted the best roulette casinos out there. Still curious about what makes a roulette site worth your time? Here’s exactly what we look for when reviewing casinos:

1. Check the Licence: Always stick with sites licensed by the UK Gambling Commission. It guarantees legal protection, fair play, and secure handling of your funds. The license number is usually listed in the footer.
2. Review Game Variety: Look for a strong mix of roulette games. The best roulette casinos will offer American and European roulette as well as French roulette, which has the lowest house edge.
3. Compare Bonus Terms: A bonus for roulette often comes with lower wagering contributions. Look for bonuses that have no less than 10% contributions, so you can make the most of your gameplay. Always read the bonus terms and look for casinos that are clearly roulette-friendly!
4. Test Mobile Compatibility: A good roulette casino should run smoothly on mobile - especially live games. We recommend testing a few spins for free before playing for real money.
5. Read Real Player Feedback: Beyond expert reviews, always check what other people are saying. Player forums and third-party sites (like Trustpilot) give insight into how a casino really treats its customers.

Types of Roulette Bonus Offers Explained

Online casinos offer a variety of roulette bonuses tailored to suit different types of players - from first-timers to seasoned high rollers. Here's a breakdown of the most common roulette casino bonuses, what they offer, and how they work:

Common Terms and Conditions for Roulette Promotions

Roulette bonuses can offer great value, but only if you understand the terms that come with them. Here are the key T&Cs to look out for when claiming a roulette promotion:

• Wagering requirements: This tells you how many times you need to wager the bonus (or bonus and deposit) before you can withdraw winnings. For example, a 30x wagering requirement on a £10 bonus means you’ll need to bet £300 before cashing out.
• Maximum bet limits: Many promotions cap the amount you can stake per round when using bonus funds, often between £2 and £5. Going over this could void your roulette bonus or any winnings
• Maximum win limits: Some offers limit how much you can win from a bonus, especially no deposit or free bet promos. Always check the max win cap, it's often around £100-£250 for smaller bonuses.
• Game restrictions: Not all roulette games count towards your bonus. Some promotions exclude certain roulette variants or restrict you to specific tables. Always check which games are eligible.
• Game contributions: This is how much each game counts towards clearing the bonus. Online roulette typically contributes 10%-20%, while slots usually count 100%.
• Time limits: Bonuses often come with an expiry date. You might have anywhere from 7 to 30 days to meet the wagering requirements, so keep an eye on the clock to avoid missing out!
• Withdrawal limits or fees: Some sites place limits on how much you can withdraw after using a roulette bonus, or charge small processing fees. A good, licensed UK casino will be transparent about this before you claim.
• Minimum risk wagering: Some casinos won't allow 'minimal risk' bets like on both Red and Black. This is because it becomes much easier to meet the wagering requirements faster. Often, players using these tactics may risk forfeiting their bonus.

Popular Types of Roulette Games in the UK

Understanding the different types of roulette games is key to making informed decisions - especially when choosing where to play and which bonuses to claim. Below, we've broken down the most popular roulette games available at UKGC-licensed online casinos, rated by oddschecker players.

Free Online Roulette 

Best for learning the ropes without financial risk. Free roulette is a great tool for beginners to test out strategies or get familiar with game rules before using real money roulette bonuses.

European Roulette

The most commonly offered version at UK online casinos, European Roulette uses a single-zero wheel, giving it a 2.7% house edge. It’s widely accepted for roulette bonus wagering and is often the go-to for both new and experienced players.

French Roulette

Similar to European but with one major difference: it includes the La Partage and En Prison rules, which return half your even-money bets if the ball lands on zero. This lowers the house edge on even bets to just 1.35% - making it the most player-friendly version, though not all casinos support bonus wagering on it.

American Roulette 

This version adds a double zero (00), increasing the house edge to 5.26%. Less common on UKGC-licensed sites, and often excluded from bonus wagering, it’s mainly suited to players seeking a higher volatility game.

Live Roulette 

Played in real-time via video stream with professional dealers, live roulette delivers an authentic casino experience. UKGC-regulated sites will usually feature top providers like Evolution and Playtech, with many offering live roulette-specific bonuses.

20p Roulette

A low-stakes version of European Roulette, this game allows bets from just £0.20 per spin. It's ideal for new players or those looking to stretch their bonus balance and meet wagering requirements at a slower, more affordable pace.

Speed Roulette 

This is live roulette with much faster rounds - think spins every 25 seconds. Popular with experienced players and those looking to complete bonus wagering quickly while maintaining live-game excitement.

Quantum Roulette

Quantum Roulette is a modern live game with randomly triggered multipliers (up to 500x) on straight-up numbers. Available at select UK casinos, it blends classic roulette with high-stakes excitement and is often featured in roulette promotions.

How to Bet on Roulette

Roulette might look complex at first, but it's one of the easiest table games to learn (second only to blackjack). Whether you're playing online or live roulette, the core rules stay the same, with just a few small differences in how bets are placed. Here’s a quick breakdown of how a typical roulette round works:

1. Players are given a set amount of time to place their bets on the roulette table.
2. The dealer (or croupier) spins the wheel in one direction and rolls the ball in the opposite.
3. You can continue betting until the dealer calls "no more bets."
4. The ball lands in a numbered, coloured pocket (this determines the winning number and colour).
5. The dealer pays out winning bets in chips and clears the losing ones. A new round begins, and players can place bets again!

Outside Bets Explained

Outside bets cover large sections of the wheel, typically 12 or more numbers. This bet type generally offers lower-risk betting options with smaller, more frequent payouts. Outside bets are especially popular with beginners or players using roulette bonuses to stretch their bankroll.

Editor's insight: "These bets are a solid choice if you’re playing with a bonus that has steep wagering requirements - they offer more consistent chances of winning, helping to extend your gameplay."

Inside Bets Explained

Inside bets are placed directly on specific numbers or small groups of numbers in the centre of the table. These bets carry much more risk but offer much higher payouts, making them attractive to players looking for bigger wins.

Top Five Online Roulette Strategies 

While roulette is ultimately a game of chance, some players like to use betting strategies to structure how they play. Below, we've ranked some of the most well-known roulette systems and share our verdict on if they’re worth considering. Because ultimately, when it comes to a roulette bonus, you want to be sure you're making the most of it.

1. Martingale

The Martingale system is an infamous roulette strategy. The idea is that with every loss, you then double your wager. This means that if you eventually win again, you should recover any previous losses, plus gain a small profit. However, it can lead to big losses if you're on a losing streak and generally only leads to very small profits.

• oddschecker’s verdict: Though it can be effective short-term, it's risky in the long run. The losses can escalate fast and you might risk hitting the table limits.

2. Reverse Martingale (Paroli)

The Paroli system flips the Martingale strategy on its head. Instead of doubling after a loss, you double your bet after each win. The aim is to ride a winning streak for a set number of rounds (often three), then reset to your original stake. It’s designed to lock in profits while keeping losses small and predictable.

• oddschecker's verdict: Paroli is considered to be safer than Martingale and ideal for short, streak-based play. Since you're only increasing bets after a win, it can help protect your bankroll.

3. Labouchere 

Also known as the cancellation system, Labouchere involves creating a sequence of numbers (e.g. 1–2–3–4), with your bet equal to the sum of the first and last numbers in the sequence. Win a bet, and you cross those numbers off. Lose, and you add the amount lost to the end of the sequence.

• oddschecker's verdict: This is much more complex than other strategies, and can spiral out of control if you hit a losing streak. There's also very little logic to the sequence of numbers.

4. D’Alembert 

The D’Alembert strategy is fairly simple and mainly works on even bets, like red or black. You increase your bet by one unit after a loss and decrease it by one unit after a win. The idea is that it can balance out wins and losses over time.

• oddschecker's verdict: This is a more conservative and easy-to-follow system that suits cautious players. It’s less volatile than others like Martingale and Labouchere.

5. James Bond 

The James Bond strategy is a flat betting system where you spread your stake across multiple bets: typically £14 on high numbers (19–36), £5 on the middle numbers (13–18), and £1 on zero as insurance. This covers over half the table, aiming for consistent, moderate wins.

• oddschecker's verdict: It's fun and easy to use, though it doesn’t improve your odds mathematically. Don't expect too many big long-term wins!
