Big Time Gaming Slots

The figures on each tile pull in different directions, and none of them is a forecast.

• RTP is what the game returns over millions of spins, not over yours. A 96% RTP does not mean you get £96 back from £100; it means the model settles there across the whole player base over a very long run.
• Volatility describes how that return arrives. A low-volatility game pays small and often; a high-volatility one goes quiet for long stretches and then pays in lumps. Two games with the same RTP can feel completely different for this reason alone.

Volatility on this page is normalised into three buckets so the table can be sorted. Where Big Time Gaming publishes a finer scale it is quoted on the individual game review.

Across the 60 titles here, Big Time Gaming’s published RTP runs from 94.19% to 97.72%, with a median of 96.44%. 53 of the 60 games with a figure sit at 96% or above, so the catalogue is priced tightly around the industry norm rather than spread across a wide range.

On volatility the set splits 55 high, 5 medium and 0 low, and 11 of the titles run on the Megaways reel system, where the number of ways to win changes every spin. That leans firmly towards rarer, larger wins: budget for longer stretches between features and use the low–medium filter above if you want a steadier session.

The reviewed releases span 2016 to 2025. Older titles are included on purpose: a game that has kept its casino placement for years tells you something a launch-week release cannot.

Big Time Gaming was founded in 2011 and is based in Surry Hills, Sydney. Evolution acquired the studio in 2021, and it now operates alongside NetEnt and Red Tiger inside the Evolution group.

Its Megaways mechanic, which varies the number of symbols per reel so a spin can pay up to 117,649 ways, first appeared in Bonanza and is now licensed to hundreds of other developers — which is why so many studios on this site have a Megaways title of their own.

• Megaways: up to 117,649 ways to win, launched with Bonanza and licensed across the industry.
• Megaclusters and Megapays: the follow-up systems in the same licensing programme.
• Part of Evolution since 2021.

If you want to play these titles for real money, our list of casinos carrying Big Time Gaming games ranks the operators we have tested with real deposits and timed withdrawals.

The RTP, volatility and maximum-win figures on this page are Big Time Gaming’s published values as recorded in our reviews. In September 2026 we cross-checked every RTP against an independent game-data feed; where no figure is published we show a dash rather than an estimate.

Our scores are argued from the maths and the feature design rather than from how a game looks, which is why the best-known title in a range is not automatically the highest scored here. Demos are free to play and pay nothing out. Casinofy is for players aged 18+; real-money play should never be treated as a way to make money — if it stops being entertainment, our responsible gambling guide lists the services that can help.
