For the wider field, our best Megaways slots guide ranks the top games built on BTG’s mechanic, and our best online slots and highest RTP slots guides put these titles in context.
Is Big Time Gaming legit, safe and fair?
Yes. Big Time Gaming holds licenses from the UK Gambling Commission, the Malta Gaming Authority and Alderney, and since 2021 it has been owned by Evolution, the largest supplier in the industry. That means deep compliance resources and audited RNG standards. You cannot supply UKGC operators without passing repeated independent fairness audits.
Every BTG slot uses a certified random number generator, and the long-term RTP and volatility of each game are fixed and published. As with any studio, an operator can deploy a lower-RTP build, so check the in-game info screen before you spin. The usual caveat applies too: a fair game does not guarantee a fast payout, which is why the table above is built only from operators we have personally cashed out from.
What Megaways actually is
Megaways is the mechanic that made Big Time Gaming famous, and understanding it explains the whole studio. Instead of fixed paylines, each reel shows a random number of symbols every spin, which means the number of ways to win changes constantly, up to a maximum of 117,649. BTG launched it with Bonanza in 2016, and it was such a hit that the studio now licenses Megaways to more than a hundred other developers, from Pragmatic Play to Blueprint. When you play a Megaways slot anywhere, the underlying mechanic is BTG’s. We rank the best of them in our best Megaways slots guide, and explain the wider mechanics in slot features explained.
Top Big Time Gaming games
BTG’s own catalog is smaller than its licensing footprint, but it is full of classics. Bonanza is the original Megaways slot and still a lobby staple. White Rabbit pairs Megaways with a feature-buy and one of the highest RTPs in the studio. Extra Chilli, Danger High Voltage, The Final Countdown and Who Wants to Be a Millionaire Megaways round out a catalog that punches far above its size.
Big Time Gaming RTP and max wins
BTG games are high-volatility with strong RTP at standard config. As always, confirm the in-game number, because a lower build changes the value.
| Game | Standard RTP | Volatility | Max win |
|---|---|---|---|
| White Rabbit | 97.24% | High | 13,066x |
| Extra Chilli | 96.82% | High | 20,000x |
| The Final Countdown | 96.45% | Very high | 44,366x |
| Who Wants to Be a Millionaire | 96.24% | High | 50,000x |
| Bonanza | 96.00% | High | 12,000x |
| Danger High Voltage | 95.67% | High | 15,000x |
The takeaway: White Rabbit’s 97.24% is one of the most generous RTPs of any high-volatility slot, while the rest sit at solid standard figures. These are swingy games built around the Megaways ways-count, so the cold streaks are real and the bankroll discipline matters.
Big Time Gaming versus the other studios
BTG’s influence is unique: it is less about its own catalog size and more about the mechanic it created and licensed everywhere. Against the high-volatility specialists like Nolimit City and Hacksaw Gaming, BTG is the elder statesman, the studio that built the framework many of them now use. Against a giant like Pragmatic Play, the irony is that Pragmatic itself licenses Megaways from BTG. If you want the original Megaways experience from the studio that invented it, Bonanza and White Rabbit are the place to start.
How to choose the right Big Time Gaming casino
The game is the same wherever the same RTP build runs, so the casino is the variable. Three checks separate a good one from a bad one.
- Check the in-game RTP. Megaways slots can be deployed at lower RTP, so confirm the number on the info screen, especially for the higher-RTP games like White Rabbit.
- Confirm fast withdrawals. These are high-variance games, so when a big win lands you want it paid quickly. Stick to the casinos near the top of our table.
- Use the demo and budget for the swings. The Megaways ways-count makes for volatile sessions. Learn a game in demo and set a hard loss limit first.
