Big Time Gaming Casinos 2026

Big Time Gaming (BTG) is an Australian studio, founded in 2011, that changed the slot industry forever. In 2016 it released Bonanza and, with it, the Megaways engine — a dynamic reel system offering up to 117,649 ways to win per spin across six reels holding 2 to 7 symbols each. Over 50 rival studios now license the format from BTG.

BTG's edge is simple: it owns the mechanic it invented, so its portfolio is the most mature on the format, and its RTPs rank among the best in the industry — Extra Chilli sits at 96.82%, Bonanza at 96%. Now part of the Evolution Group, BTG ships fewer titles than giants like Pragmatic Play, but each release still lands as an event.
