Big Time Gaming Slots and Casinos (2023) – Our Top Picks for EU Players

Big Time Gaming (BTG) is an uncontested shooting star in iGaming software development, the first-ever company to develop Megaways and Megaclusters reel mechanics. BTG is best known for Bonanza Megaways, Lil’ Devil, and Danger High Voltage online slots, and an industry game-changer – the Bonus Buy feature.

At the helm of the 2011-founded provider are enthusiastic people with decades of experience in games development, strictly focused on quality instead of quantity and ready to take on the industry’s big guns. The earliest signs of a breakthrough date back to February 2015, when BTG released the first “Megaways” game, Dragon Born!

Still flying somewhat under the radar, the trademarked game engine with dynamic reels gathered momentum in the player community. And with the release of their blockbuster slot Bonanza in December 2016, it virtually exploded.

Bonanza Megaways

An online slot Bonanza was released in December 2016 by Big Time Gaming. It has had quite an impact on the casino community due to its unique Megaways game engine with six reels, each with up to seven symbols and a maximum of 117,649 ways to win.

  • The number of ways is randomly determined on every spin leading to a sheer indefinite number of reel and row combinations;
  • Any win landing will see the symbols explode to make room for new ones to drop in place. Score another win, and the chain reaction continues until no new wins occur;
  • The key to the mega wins is though, in the free spins round, which is triggered when you land four scatters spelling the world GOLD within one spin sequence. You’ll get 12 free spins with each extra scatter adding +5 free spins;
  • During the feature, an unlimited multiplier increases by 1x after each winning reaction.

In the slot Bonanza, the Big Time Gaming Megaways engine delivers 64 to 117,649 ways to win using dynamic reels and a complex maths model that randomly chooses two to seven symbols for each reel for every spin. The virtually unlimited number of reel combinations is further enhanced with a reactive win mechanic. Winning symbols are removed to let new ones drop into the spaces and potentially start a chain of winning reactions. It all comes to an end once no new wins occur.

Spelling out G-O-L-D on the reels will trigger the free spins round. The often elusive D has become an internet phenomenon in forums and the online casino community at large.

BTG Megaways Slots

Big Time Gaming has released a balanced mix of Megaways slots games, each rocketing into the top of the playing charts. Danger High Voltage, Extra Chilli, Lil’ Devil, and The Final Countdown are just a few examples that showcase their vast creativity.

Not one to rest on its laurels, CEO Nik Robertson offered Megaways licences to other game software providers, allowing the game engine to develop its full potential, and focused himself on what could be the next big thing in online gaming. “Star Clusters Megaclusters” is bound to let players rethink how grid slots can deliver an exhilarating gaming experience.

Max Megaways™ Slot

Max Megaways, like many Big Time Gaming slots, has a lot of action, but it can be confusing at first. The number of symbols on the reels and the number of ways to win constantly change, while there are also four different types of wilds in play. Despite this, or perhaps because of it, the slot is exciting and potentially rewarding. The RTP of Megaways Slot is 96.37%.
