Why Are BTG Casinos so Popular in the UK

BTG games are instantly recognizable. They have a specific vibe to them: their names are appealing and memorable, the first-class graphics never fail to impress, and the upbeat music keeps you playing. But most other high-quality developers offer the same level of quality, so what makes BTG casinos so popular among British players? – It’s mostly the Megaways game system.

The first slots that appeared in the online gambling industry were classic. They offered a few paylines and a limited range of bonuses. When BTG presented its Megaways slots, the players got hundreds of thousands of ways to win with a single spin.

Big Time Gaming casinos in the UK still feature simpler slots, but the addition of these special games makes them more versatile. Before you start playing, let’s list some of the main characteristics of Megaways games:

  • The games are more complex than the usual slots in the industry. Before each spin, the reel modifies in size and symbols. You will see the number of potential winning combinations at the top of the game.
  • Some of the games (such as Who Wants to Be a Millionaire) feature an extra reel in a vertical line. It adds an extra symbol on each spin.
  • The games’ mechanics give you a chance to win a higher payout, but that fact increases their volatility.
  • BTG is not the only provider of Megaways slots. Blueprint Gaming, Scientific Games, Relax Gaming, Red Tiger Gaming, and a few others also offer slots based on this system. However, BTG was the first developer to come up with it, and it’s still a leader in the category.

In addition to the special system the provider offered for slots, Big Time Gaming is also known for its TopCards. For those who like the quick thrill of scratch cards, this digital format works.

The bottom line is: BTG casinos are popular because they bring something new to the industry. This software developer has launched some of the most unique online casino games.

How Do We Rate and Review BTG Online Casinos

Through our reviews of UK casinos, gamblers learned to trust our judgment. We guide them towards the most exciting offers, which increase the value of their money and enhance the excitement they get from playing.

Are you interested in the way we review and rank Big Time Gaming casinos? All of them feature BTG software, which will never change from one website to another. So what makes certain gambling sites a better choice among their competitors?

We are guided by a few criteria, which we use comparatively for ranking purposes:

Terms and Conditions (Fairness)

Everything may seem proper when you read the promises on the main page, but they mean nothing if they aren’t supported by actual terms and conditions. This section ensures the company provides fair rights and support to its players. If you’re protected by the website’s terms, you can enjoy a secure gambling experience.

Promos and Bonuses

The UK Gambling Commission is the main licensing authority for British online casinos, but it’s not the only one. Under the Gambling Act 2005, a few whitelisted jurisdictions also issue licenses that are accepted in the country: Tasmania, Isle of Man, Gibraltar, Antigua and Barbuda, Alderney, and EEA countries. With this fact, the number of casinos that can offer services to Brits consistently grows.

The huge competition imposes a standard: Big Time Gaming casinos must offer great bonuses to attract more gamblers to play. These bonuses may include free spins, welcome deposit matches, loyalty credits, cash-back programs, and more.

Variety of Games

BTG offers a massive selection of games, which are not always available in full by the websites that feature this provider. Plus, BTG online casinos have the right to include multiple providers in their offer.

When we rank websites, we consider the game variety as an important factor. A player likes having more options, so they won’t have to move from one online casino to another when they want to spice up their routine.

Experience and Reputation

If the website is brand-new, it may be good. However, it will take a while for it to gain its reputation among players. It needs to attract a massive community of gamblers, who will prove that the site is safe and pays out regularly.

By collecting all available information about the current reputation of different websites, we use this factor in our ranking system.

Mobile Play

BTG games are suitable for the smartphone and tablet format. But does the online casino work well in its mobile version? Is there a special app you can download to play on the move? We test the mobile play options and give you feedback in our reviews.

Banking Options

Can you use PayPal, other e-wallets, debit cards, bank transfer, and even cryptocurrency in a specific online casino? Are the withdrawal options as versatile as the ones for depositing? Gamblers need this information before they choose a website. We make sure to include it in our evaluations.

Top List: Best BTG Slots to Try

The selection of games is not as big as with other providers. BTG has been in the industry for over a decade, but the team takes time before releasing new titles. Still, there are 20+ slots to play at the moment.

All of them are suitable for mobile play. If you’re looking for Big Time Gaming free play, you can try all games through the official website. At the moment, there aren’t any progressive jackpot games available. We expect a big surprise from BTG in that department. We’ll list the top slots from this provider, along with their return to player rates.

BTG SlotDescriptionRTP
Star ClustersAt first sight, it’s a regular cluster slot with a 4×4 grid. The symbols are common in the gambling world: gemstones and diamonds. The cascading reels are a special twist. Whenever you form a cluster, the grid modifies and increases your chances to spin into new clusters.96.54%
Monopoly MegawaysThe slot is based on the classic Monopoly game. It features cascading reels and a board with Mr. Monopoly assisting with the game’s rules. The golden dog, car, ship, and hat are the highest paying symbols. Those are the ones you want to see in a winning combination.96.39%
Who Wants to Be a Millionaire?Don’t worry; it’s not a game of knowledge like the TV show it was inspired from. This is a slot, based on luck just like any other. The game has 6 reels with up to 7 symbols (the number varies). There are 116,649 potential winning combinations. When you hit one, the symbols explode and you get another chance to hit a winning combo.96.2%
Bonanza MegawaysThis is by far the most popular Megaways game ever launched. The theme revolves around a gold mine, which gives you 117,649 possible winning combinations. You get 6 reels for start, and each of them will reveal 2-7 symbols.96%


There’s an important thing to keep in mind when grabbing a bonus: it comes with strings attached. The terms and conditions involve playthrough requirements. If Big Time Gaming casino imposes a 20x wagering condition, it means you’ll have to play through the bonus amount 20 times before withdrawing. If you got £20 as a bonus, you’ll be able to get your winnings only after you play with £400 on the website.
