About Big Time Gaming

Big Time Gaming is an Australian studio that invented the Megaways slot mechanic in 2015 — a randomly-varying reel structure that produces 117,649 ways to win per spin. Megaways has since been licensed to virtually every major slot studio and now exists as a sub-genre in its own right.

BTG was acquired by Evolution in 2021 and now operates inside the group's content stable. The original BTG titles — Bonanza, Extra Chilli, White Rabbit and Danger High Voltage — remain high-volatility cult favourites with cult-tier max win potential (10,000-50,000x stake).

BTG's catalogue is small (around 30 titles) but each release is a major industry event because of the studio's track record on max-win potential.
