Big Time Gaming
Big Time Gaming (BTG) is a Sydney-founded developer established in 2011 by Nik Robinson. The studio is the inventor and patent-holder of the Megaways™ mechanic — a variable reel format in which the number of symbols per reel changes on every spin, generating up to 117,649 ways to win on a standard six-reel layout.
The best casinos with Big Time Gaming
Evolution AB acquired BTG in 2021 for an initial payment of €220 million plus earn-out clauses, integrating it alongside NetEnt and Nolimit City. BTG titles have been available in the regulated Ontario market since launch day under Evolution Group’s AGCO registration. The studio deliberately keeps its catalogue small — approximately 70 original titles — focusing on high-quality, high-variance releases rather than volume.

Bonanza Megaways (2016) introduced the Megaways format to a global audience and remains the reference point for the entire genre. The mine-cart row above the main reels adds reactive symbols after each Avalanche, a mechanic that feeds directly into the unlimited progressive multiplier during free spins. White Rabbit Megaways (2017) holds one of the highest default RTPs (97.24%) in any major provider’s catalogue — a figure worth noting alongside the configurable-RTP caveat that applies industry-wide.
Note on RTP: Operators may configure lower RTP variants. The Megaways mechanic also produces significant volatility — sessions without a bonus trigger can be lengthy.
Software Features
Megaways is the defining feature of the BTG catalogue, but the studio has also developed Megaclusters™ (a grid that splits symbols into smaller ones) and Megapays™ (a random progressive jackpot). The Feature Drop / Bonus Drop mechanic — which allows players to guarantee the next bonus trigger in exchange for a higher stake — originated at BTG before spreading to other providers. Bonus Drop is not available on Ontario-regulated sites.
Big Time Gaming in the Canadian Market
Many Ontario casino lobbies include a dedicated Megaways filter populated with BTG originals alongside licensed Megaways titles from other developers. For Canadian players who discovered online slots through the Megaways format, BTG pages represent the original source. Big Time Gaming Canada availability covers all major Ontario operators via Evolution’s distribution.
Suitable for players who enjoy high-variance, high-potential mechanics, are specifically looking for Megaways slots in Ontario, or want to explore the originator of a format they have already encountered on licensed titles from other studios.
