White Rabbit Megaways

White Rabbit Megaways is a Big Time Gaming slot themed around Lewis Carroll's Alice in Wonderland. Released in 2017, it stands out in the Megaways genre for two reasons: a 97.72% RTP — one of the highest published figures among major Megaways titles — and an expanding free spins mechanic that can grow the reel layout to 8 rows per reel, creating up to 248,832 ways to win. Volatility is very high, max win is 13,000× stake.

How White Rabbit Megaways Works

The base game uses a standard 6-reel Megaways grid. The key differentiator is the free spins expansion mechanic:

Caterpillar symbol / Reel Extend: During free spins, a Caterpillar symbol landing on any reel permanently extends that reel by one row. Reels can expand from the base maximum of 7 rows up to 8 rows each. With all six reels at 8 rows, the ways-to-win count reaches 248,832 — exceeding the standard Megaways 117,649 maximum.

Feature Drop (Bonus Buy): White Rabbit was one of the first BTG slots to include Feature Drop — direct purchase of the free spins feature at a fixed cost (typically 100× stake). Available at MGA-licensed and offshore casinos; banned at UKGC operators in Great Britain.

Free spins multiplier: A win multiplier increases by 1 with each Reaction (cascade) during free spins — the standard BTG unlimited multiplier mechanic. No cap. The combination of an expanding layout (up to 248,832 ways) and an accumulating multiplier produces the game's largest theoretical wins.

White Rabbit RTP — 97.72% in Context

97.72% is exceptionally high for a major Megaways title. The average for Pragmatic Play and Blueprint Megaways slots is 95–96.5%. BTG's own Bonanza is 96.0%; [Extra Chilli](/slots/big-time-gaming/extra-chilli/) is 96.79%. White Rabbit at 97.72% returns meaningfully more to players over long sessions — but the very high volatility means individual session outcomes remain highly variable regardless of RTP. The higher RTP benefits are realised over hundreds of thousands of spins, not individual sessions.
