Big Time Gaming is the inventor of the Megaways slot mechanic – and its library is packed with hits. Below are ten of the best BTG slots to try at UK casinos, each offering exciting gameplay, unique features, and strong payout potential.
The slot that started the Megaways craze. Set in a gold mine, Bonanza Megaways offers up to 117,649 ways to win, cascading reels, and a high volatility setup. Land the GOLD scatter symbols to trigger free spins with unlimited multipliers. Max win: 12,000x your stake.
Inspired by Electric Six’s cult anthem, this electrifying slot offers two free spins modes (Gates of Hell and High Voltage), sticky wilds, and big multipliers. It’s one of BTG’s most chaotic and entertaining releases.
Based on the classic TV game show, this slot brings quiz-themed bonus rounds and unlimited win multipliers during free spins. You can gamble your way up the Hot Seat ladder to unlock bigger wins.
Spice things up in this Mexican-themed Megaways slot. Extra Chilli features cascading reels, free spins, multipliers, and the innovative Feature Drop – letting you buy the bonus round with collected coins.
Inspired by Alice in Wonderland, White Rabbit is packed with fantasy visuals and high-paying features. Expanding reels, free spins, and Feature Drop options create win potential of over 18,000x your stake – with one of the highest RTPs in BTG’s library.
A smart mash-up of board game and slot gameplay, Monopoly Megaways introduces Reel Adventure – where each spin moves you around the board, unlocking multipliers and properties. Big wins await in the free spins round if you build your way up Park Lane and Mayfair.
This vibrant slot introduces the Heartstopper bonus, triggered after collecting tokens across multiple spins. With huge multiplier potential and stacked wilds, Royal Mint Megaways is a serious win contender.
Lil Devil stands out for its dual free spins rounds – Be My Angel and Dynamite Lover – each offering different volatility levels. Combine this with sticky wilds, multipliers, and a max payout of 40,960x for an unforgettable slot experience.
Opal Fruits brings a space-age theme and multi-directional cascading reels to the table. Free spins with increasing multipliers are the main draw, and its quirky visuals give it a unique charm. Max win: 36,000x.
Enter the ancient world of pharaohs and hidden treasures. Book of Gods offers expanding symbols during free spins and a Feature Drop buy-in system. While less known than BTG’s Megaways hits, it’s a solid pick if you’re a classic slot fan.
Both Big Time Gaming and Pragmatic Play are giants of the iGaming world – but they offer very different styles of gameplay. Whether you’re into complex mechanics or action-packed bonus rounds, here’s how these two popular providers compare.
Big Time Gaming is the original creator of the Megaways mechanic, with highly volatile slots that often exceed 10,000x max wins. Its portfolio is smaller but highly specialised, featuring legendary games like Bonanza Megaways, Extra Chilli, and Lil Devil.
Pragmatic Play, on the other hand, produces a much higher volume of games. It’s best known for Gates of Olympus, Sweet Bonanza, and the ‘Pay Anywhere’ mechanic seen in many of its top-performing slots. While less experimental than BTG, Pragmatic’s games tend to load faster and offer more frequent bonus rounds.
