Professor Big Win Super Wheel

Professor Big Win Super Wheel: What's Different

Professor Big Win Super Wheel takes the same electrified laboratory setup as its Atomic Slot Lab sibling and adds an optional side bet in the form of a Super Wheel, giving players an extra, entertainment-focused layer on top of the core Replicating Reels formula. Released on 16 January 2026, it shares the same core numbers as the original — a 5-reel, 4-row grid, 40 fixed paylines, an RTP of 95.52%, medium volatility, and a maximum win of 6,600x the stake, with betting from 0.4 to 120 per spin.

Theme & Presentation

The lab setting returns largely unchanged, with Professor Big Win once again playing host to a run of electricity-powered experiments. Crackling effects, animated machinery and bold, high-contrast symbols carry the experimental theme through the whole game, blending a sense of humour with genuine intensity during the bigger moments. It's a lively, distinctive presentation that leans into spectacle without losing clarity on the reels themselves.

Core Gameplay

Winning combinations form by matching symbols left to right across the 40 paylines, with bets staying consistent between the base game and bonus features — unless, that is, the Super Wheel side bet is switched on, which increases the total wager in exchange for the extra layer of engagement it brings. The core reel mechanics remain untouched by that side bet, so players who'd rather skip it can play the base game exactly as they would the standard Professor Big Win release.

Replicating Reels & Free Games

The heart of the game is still the Replicating Reels Feature, where wild symbols help complete winning lines, scatter symbols trigger the bonus when fully stacked, and TR symbols set off reel-wide transformations directly within the base game. Free games are triggered by a fully stacked scatter, four symbols high, landing on reels 2, 3, 4 or 5, awarding 7 free games to start, with the triggering reels transforming into Replicating Reels before each subsequent spin in the round.

The Super Wheel Side Bet

The headline addition here is the Super Wheel itself — an optional extra wager layered on top of the standard game that's designed purely to broaden the entertainment value and exposure for players who want more going on than the base reels alone provide. It doesn't alter the underlying RTP, volatility or max win of the core slot; it sits alongside it as a separate feature for those who opt in.

RTP & Volatility

With the same 95.52% RTP and medium volatility rating as the standard release, the underlying mathematics here are identical to its sibling — this version is really about the added Super Wheel option rather than any change to how the core reels behave.

Final Verdict

Professor Big Win Super Wheel is best thought of as the original game with an extra dial to turn for players who want more variety in how they engage with each session. If you've enjoyed the standard Replicating Reels format before, the Super Wheel is a straightforward way to add some variance to proceedings.
