About Big Time Gaming
Big Time Gaming was founded in 2011 in Sydney, Australia by Nik Robinson, with chief engineer Huw McIntosh and art director Ian Schmidt rounding out the core founding team. For the first few years they were a respected but niche developer. That changed in 2016 with the release of Bonanza, the slot that introduced the world to the Megaways engine and, arguably, reshaped what a modern online slot looks like. In 2021 the studio was acquired by the Evolution group, which dramatically expanded its distribution while letting BTG keep its distinctive, engineer-led design voice.
The defining BTG idea is Megaways itself. On a normal slot each reel shows a fixed number of symbols; on a Megaways slot the number of symbols on each reel changes on every spin, typically between two and seven, so the total number of ways to win recalculates each time — up to 117,649 when all six reels are full height. There are no fixed paylines: matching symbols on adjacent reels from the left simply pay, however many positions line up. It is a genuinely clever piece of maths, and it is the reason their games feel alive and unpredictable in a way fixed-line slots do not.
What makes BTG distinct is how thoroughly they licensed that engine out. Megaways is not a BTG exclusive — they sell it as a toolkit, and you will find the Megaways badge on titles from Pragmatic Play, Blueprint Gaming, Red Tiger, Relax Gaming, NetEnt, Playtech and IGT, among others. So when you play a "Megaways" slot, the core mechanic is BTG's invention even when the studio name on the screen is someone else's. That makes Big Time Gaming one of the most influential names in the industry despite being a comparatively tiny company. Pair Megaways with the studio's other hallmarks — cascading Reactions, an unlimited win multiplier that climbs through the free-spins round, and the optional Feature Drop that buys you into the bonus — and you have the BTG signature sound.
The honest caveat with this studio is variance. BTG builds high to very high volatility games as a house style; even their "medium" titles run hot. Headline RTP on the flagships (Bonanza, Extra Chilli, Danger High Voltage) typically sits around 96.0–96.4%, with White Rabbit notably higher on its bonus-buy version — but RTP is frequently **configurable** by the operator, so the same title can run lower at a given casino. As with any game provider, read the RTP line before you spin. With BTG, the swings are the whole point, so expect long dry stretches between the big hits.
Big Time Gaming signature mechanics
Every studio has a handful of mechanics it does better than anyone — the things you recognise the moment the reels move. Here are Big Time Gaming's.
Megaways (shape-shifting reels)
BTG's flagship invention. The number of symbols on each reel changes every spin — up to seven per reel — so the ways to win recalculate each time, reaching 117,649 when every reel is full. No fixed paylines; adjacent matching symbols from the left simply pay. The single most-copied mechanic in modern slots.
Reactions (cascading wins)
BTG's name for tumbling/cascading reels: winning symbols disappear and new ones drop in from above, so one spin can chain into several consecutive wins. It pairs with Megaways to make the action feel relentless rather than line-by-line.
Unlimited free-spins multiplier
In the bonus round of Bonanza, Extra Chilli and others, a win multiplier climbs by one with every successive cascade and never resets until the feature ends. This is where BTG's biggest payouts hide — and why the bonus is so feast-or-famine.
Feature Drop (bonus buy)
An optional purchase — often around 100x your stake — that drops you straight into the free-spins feature instead of waiting to trigger it naturally. Convenient, but it does not raise your long-run RTP; it just front-loads a huge amount of variance into one click.
Megaclusters & Megapays
Two later twists on the formula. Megaclusters replaces ways-to-win with clusters that split each winning symbol into four smaller ones, multiplying the grid. Megapays adds a progressive jackpot layer (Bonanza Megapays, Who Wants to Be a Millionaire Megapays) on top of the Megaways base.

How I approach Big Time Gaming games
No tip beats the house edge — there is no winning system. These are about playing this studio's games informed and keeping it fun.
- Understand that Megaways is the maths, not magic. 117,649 ways sounds enormous, but the RTP already prices it in — more ways to win is a different shape of variance, not a better deal. Treat it as a mechanic to enjoy, not an edge.
- Read the RTP in the info panel every time. BTG headline figures cluster around 96%, but many titles ship in configurable variants and operators can run a lower one. The same Bonanza at two casinos may not be the same maths.
- Respect the volatility — it is the house style. Extra Chilli and Bonanza are built for long droughts and rare big hits. Size your stake so a cold run of 100+ spins does not end your session, because that run is completely normal here.
- Treat the Feature Drop / bonus buy as entertainment spend, not strategy. Paying ~100x to skip into the bonus does not improve your RTP; it compresses a swingy session into one expensive spin. Set the price you are willing to lose before you click it.
- The unlimited multiplier is where the headline wins live — and where most bonuses disappoint. A few cascades and nothing, then occasionally a multiplier that runs away with it. Do not judge the game by the rare clip you saw a streamer post.
- Demo first. BTG games are widely available in free play. Spin a Megaways bonus a dozen times for free to feel how rarely the multiplier climbs high before you ever risk real money.
