248,832 ways — a Megaways record
A standard Megaways build tops out at 117,649 ways (6 reels x 7 symbols max). White Rabbit pushes further:
- 5 reels with 2-7 symbols in the base game = up to 117,649
- Extending Reels during Free Spins = up to 12 symbols per reel
- With 5 reels x 12 symbols, that's a theoretical 248,832 ways
Once every extension is active, each reel offers 12 chances to hit across 5 reels — a massive density of combinations.
Extending Reels — the signature mechanic
A mechanic unique to the market. During Free Spins:
| State | Symbols per reel | Effective ways |
|---|---|---|
| Initial Free Spins | 2-7 per reel | up to 117,649 |
| Extension level 1 | Up to 9 | ~150,000 |
| Extension level 2 | Up to 12 | 248,832 |
Extensions are triggered by collected cookies. The more cookies you gather during Free Spins, the further the reels stretch.
Caterpillar wild — a multiplier boost
A one-of-a-kind mechanic:
- The Caterpillar wild lands randomly during the base game
- When it triggers, it adds 4 extra wilds to the grid
- Every one of those wilds carries a 3x multiplier
- Any winning combination that includes them gets multiplied by 3
It's the alternative route to big base-game wins for players who don't want to wait for Free Spins.
Free Spins up to 75 in total
Triggered by 3 March Hare scatters:
| Cycle | Spins awarded |
|---|---|
| Initial trigger | 15 spins |
| Cookie collected (extension 1) | +5 spins |
| Cookie collected (extension 2) | +5 spins |
| Etc. | Up to 75 spins total |
75 Free Spins with extending reels fully active is the main path toward the 10,000x cap.
The cake/cookie collect feature
A base-game mechanic:
- Cookies appear at random during the base game
- You collect them progressively
- Once you reach the threshold, a partial cookie reveal occurs
- Cookies collected in bonus unlock the extending reels
It's a long-term progression system that rewards extended sessions rather than pure luck.
