To give you the most accurate BetMGM review, our experts thoroughly tested all the features the operator offers to regular British customers. We registered our real-money accounts on multiple devices, which we also used to explore the navigation and accessibility features on the BetMGM website. We analysed the gambling site’s aspect and design on mobile and desktop.

Our team then redeemed the welcome offer to help us test the BetMGM game catalogue. We tested over 50 different slot titles and 10 distinct live dealer games with bets ranging from £0.10 to £5. Some of the games include 777 Hot Reels, Eye of Horus and the exclusive BetMGM Roulette supplied by OnAir Entertainment.

After we were satisfied with our testing, we requested a payout of our remaining £25 via PayPal and received our funds in 18 hours.

The platform is well-designed, easy to navigate, and features dedicated mobile apps for both iOS and Android, which we found to be a convenient touch. While the £10 minimum deposit is standard, we were impressed by the 24-hour payout speed, although the game library is smaller compared to other casinos. The lack of a loyalty program might disappoint some regular players.

Best Big Time Gaming Casino Bonuses in July

All casinos that offer Big Time Gaming slots have bonus packages for their players.

You can expect the following casino bonuses when you play BTG games: welcome bonuses, free spins valid for selected games, and VIP offers for existing players.

Typically, deposit bonuses come with fewer bonus wagering requirements than free spins and no-deposit offers. So, take the time to figure out what will work best for you before you settle on a casino.

Of the top Big Time Gaming slots we tried, the best-recommended Megaways slots for bonuses are:

• 88 Fortune Megaways
• Wheel of Fortune Megaways
• Hypernova Megaways.

These are available on our BTG casinos list above. Since Big Time Gaming does not create live dealer games, you’ll have to look at other sites with live casino promotions in the UK.

How We Review Casinos Online with Big Time Gaming

With over 8 years of experience in the online gambling industry, our KingCasinoBonus specialists have built a reputation for delivering in-depth, unbiased reviews. Led by industry experts like Vlad George Nita, we ensure that each casino we recommend meets the highest standards for player security and fairness. Our method goes beyond surface-level checks, as we dig deep into every aspect of the casino experience, focusing on what truly matters to players.

• Game Selection: We don’t just look at the number of games a casino offers—we focus specifically on the range of Big Time Gaming slots available. From iconic Megaways titles like Bonanza to other fan favourites, we check that the library is diverse and includes both new and popular BTG games.
• Licensing and Security: The first thing we confirm is that the casino holds a valid UKGC license. This guarantees that the site is fully regulated, adheres to safety standards, and protects your personal and financial data.
• Bonus Fairness: Our bonus experts thoroughly examine the promotional offerings, especially in relation to BTG games. We test bonuses by registering, depositing, and clearing the wagering requirements, ensuring you get a full overview of how player-friendly the bonuses are.
• Payment Methods and Withdrawal Speed: We make sure that the casino supports a variety of secure payment options, including PayPal and other trusted methods. Additionally, we test the withdrawal process to see how quickly funds are transferred.
• Customer Support: This includes interacting with customer support to assess response times and the overall helpfulness of the team. We also review the chat service to ensure you receive timely and professional assistance.

Top 10 Big Time Gaming Slots

Let’s see the best BigTime Gaming slots you will encounter in the best slots sites in the UK in % and.

Our Take and Recommendations for Players

Our experts invested over 24 hours playing and reviewing these BTG slots so you can pick the best games to play.

Based on their research, BTG makes some of the most exciting and innovative slots. Most of the games in the top 10 use features like Megaways, cascading wins, and tumbling reels to give you many winning chances on every spin. Plus, the math models and RTPs are certified fairly.

Bonanza, Extra Chilli, and White Rabbit are some of the top slots we recommend. These high-volatility games can pay out huge wins thanks to the Megaways mechanics. Lower variance slots like Book of Gods, Queen of Riches, and Who Wants to Be a Millionaire are solid picks if you prefer smaller but more frequent payouts.

Other Key Features of Big Time Gaming Casinos

While Big Time Gaming is well-known for its revolutionary Megaways mechanic and high-quality slots, BTG-powered casinos often offer a range of additional features that enhance the overall gaming experience. These features go beyond just the games, providing players with a more well-rounded and enjoyable experience. Here’s what you can expect when playing at Big Time Gaming casinos:

Security Measures for Big Time Gaming Casinos in 2025

When selecting a Big Time Gaming casino, it’s crucial to prioritise platforms that offer top-notch security features. These measures protect both your personal and financial information, ensuring a safe and fair gaming environment. While selecting the operators on our list, we look for these essential features:

Top Big Time Gaming Software Provider Alternatives

Big Time Gaming vs Yggdrasil

Big Time Gaming and Yggdrasil are relatively new in the online casino industry. BTG was founded in 2011, while Yggdrasil came into existence in 2013. Yggdrasil has produced over 160 high-quality games, while BTG has only managed a third of that.

Yggdrasil also has more table games and runs live casino studios. It also releases new titles more frequently, with a new game coming out roughly every month. You can play the latest Yggdrasil games on Bally Casino.

BTG, on the other hand, may have better quality games and is behind the game-changing Megaways mechanic. Sadly, these are not enough to give it a better rating than Yggdrasil.

BTG vs Play’n GO

We tested a few games on Rhino.Bet casino and our biggest surprise was the number of Play’n Go slot options we found. Most of the games seemed pretty high-quality, too. The lack of live casino games doesn’t count against Play’n Go since they regularly release 3-to 4 slots per month, which makes up for the shortcoming. Moreover, BTG doesn’t have live dealer games either.

It’s not all doom and gloom for BTG fans, though. The Megaways engine is a strong selling point with its high max win potential. BTG slot offers are also quite good for a game provider with just over 40 online slot games. We have a very high opinion of Play’n Go casinos, but there is not much they offer that Big Time Gaming sites don’t.

Big Time Gaming vs NetEnt

NetEnt is a benchmark for many up-and-coming providers of online casino games. NetEnt casinos seem to get everything right, from game quality to portfolio diversity to user safety and compliance with industry standards.

If you want to test NetEnt games, try a reputable casino like Pink Casino. You can also find BTG slots like Extra Chilli and Bonanza Megaways. You won’t notice much of a difference, at least not until you factor in quantity, consistency, portfolio size, and other factors outside slot quality.

Get to Know KingCasinoBonus

At KingCasinoBonus, our goal is to provide you with professional casino reviews and trustworthy information. Our main objective is to help you make the best decisions since the beginning. In such a way, we have always tried to provide useful insights into the world of online casinos and continuous updates. Our purpose is to advocate safe and responsible gambling while pointing in the right direction toward the most appropriate platforms, in this case Big Time Gaming casinos.

With years of experience in the industry, our team of reviewers truly understands what makes or breaks a great casino. Each review is honest and based on real data.

Moreover, we update our database constantly and add a new casino every 15 days so that you get the latest ones. Transparency is the greater commitment, so you also get to see how we review certain aspects, gather reliable information and make a comprehensive analysis.

Why Choose Big Time Gaming Casino Sites?

Big Time Gaming casinos are great at keeping up with older, more established gambling companies. Many new UK online casinos feature BTG slots, and you can tell that the company is repaying their faith.

The provider has its shortcomings. The BTG portfolio is too narrow, for starters. And if you choose to focus on slots, you don’t get enough from BTG alone. Luckily, you can find many other reputable slots providers on Big Time Gaming casino sites. In terms of payout speed, the best BTG casinos like Bally Casino and Casushi process PayPal payouts relatively quickly, in 1 day

Overall, the pros of playing BTG slots outweigh the cons. We would 100% recommend casinos that offer BTG slots, and we believe plenty of sites will meet your gaming expectations. For the best experience, we recommend you start with the best Big-Time Gaming casinos like Bally Casino, Casushi or Virgin Games.

Pros

• Great graphics and visuals
• Links with many top casino sites in the UK
