Big Time Gaming invented Megaways and still ships its own titles with Feature Drop built in. Outside the UK system you can get that buy back and stake above £5, which raises the cost of a bad session just as much as the ceiling. Compare the RTP in the game's rules with the studio's own figure and set a spending limit before the first spin.
If you are searching for Big Time Gaming not on GamStop, you most likely want the Australian studio's Megaways slots the way they were built: with Feature Drop on the menu and without a £5 or £2 limit on each spin. Both of those restrictions come from UK licensing rules, so the same game behaves differently depending on where the casino holds its licence.
Big Time Gaming created Megaways, the reel modifier that gives every reel a different number of symbols on each spin. On the studio's six-reel titles that tops out at 117,649 ways, and BTG licenses the mechanic to many other developers, which is why it now turns up well beyond the studio's own catalogue. Our guide to how Megaways works shows how the ways count is built from the reel heights.
Since mid-2021 the studio has belonged to Evolution, the Swedish live-casino group, which completed the purchase on 30 June that year once regulators had approved it. BTG still publishes games under its own name from its Surry Hills office in Sydney, where recent releases include Megapots jackpot games and Monopoly titles.
Below you will find what changes when you play BTG outside the UK system, what the buy feature really costs, how to confirm which RTP your casino has loaded and how to keep the higher limits from running away with your balance.

Big Time Gaming not on GamStop: what changes away from UK rules
Feature Drop and buying the bonus. On its White Rabbit page BTG describes Feature Drop as a way to purchase the bonus at any time, with the price starting at a set level and falling each time a BTG coin lands. Extra Chilli carries the same option. The Gambling Commission banned the sale of bonus features in 2021, so UK-licensed casinos serve these games with the buy taken out, while offshore lobbies can leave it switched on. Paying for the feature does not lift the game's return: it swaps a long run of small stakes for one large one. The explainer on bonus buy pricing walks through the maths.
Spin limits. British licence conditions hold each online slot spin to a £5 maximum, with a lower £2 ceiling for players aged 18 to 24. A casino licensed abroad will set its own maximum, and on a Megaways game where a Feature Drop costs a multiple of the base bet, spending can climb very quickly. The bankroll simulator shows how long a balance tends to last at a given bet size.
Which RTP is loaded. BTG's own game pages list Bonanza at 96.00% and White Rabbit at 96.42%, while Extra Chilli is shown with a range from 96.15% to 96.41%. A range is your signal that casinos can receive more than one build. Open the paytable or rules screen inside the game and compare the figure printed there with the studio's. Across Extra Chilli's published range the gap is small: staking £1,000 in total costs about £36 on average at the top end and about £39 at the bottom. A build several points lower would cost far more, and the RTP cost calculator runs that sum at your own stake.
Volatility. BTG does not print a volatility grade on these pages, so treat its Megaways titles as swingy by design: a large share of the return sits inside the free spins and long dry spells in the base game are normal. Our piece on slot volatility explains what that means for session length. The same reel idea now runs through other studios' games too, and the Megaways slots not on GamStop page collects them in one place.
Where to look. Our top pick, Maxxed, carries 5,000+ games and accepts BTC, ETH, USDT, SOL and LTC, with a sportsbook running on the same balance. Search its lobby by studio name to see which BTG titles are live, then check the RTP inside each one before you stake. If you lean towards book-style free spins instead of reel modifiers, the Play'n GO studio guide covers that side, and Hacksaw's offshore catalogue is the obvious comparison for buy-heavy slots.
