Big Time Gaming's Alice-themed Megaways slot runs 5 reels at two to seven rows — 16,807 ways — growing to twelve rows and 248,832 ways in free spins. The studio's own page dates it to 25 October 2017: the first BTG title with a buy-the-feature button.
Which matters, because the figure you read elsewhere is probably not the one your lobby runs. Four returns are in circulation — the studio's own page publishes 96.42%, while the review industry quotes 97.24%, 97.72% and 97.77%. This page maps every figure to the build it describes and prices the gap in pounds.
The studio publishes 96.42%; the review industry quotes up to 97.77%. Your lobby runs one of them, and the difference is £1.35 on every £100 turned over.
Read the panel before you read the reviews. Extending Reels is the rare feature that changes the odds while it runs, and a 38.04% studio hit frequency keeps the base game ticking while you wait. But the return is not the settled number the industry repeats: the studio publishes 96.42%, the corpus quotes up to 97.77%, and only your own lobby's figure governs your session — the arithmetic is in the configuration panel.
Hand-drawn Wonderland characters sit behind the card royals — a stacked ten is a Dodo, a stacked jack a Mad Hatter — detail that appears only when symbols land tall. The real visual event is structural: the frame climbs as rows are added, so the board at four rows is not the board at twelve.
The base game keeps its music low and its win cues short — under the Commission's technical standards a return at or below your stake may not be celebrated at all. Then the feature starts, the audio steps up with each cupcake, and the ear tracks reel height before the eye does.
Every character does a job. The caterpillar turns symbols into Bonus Wilds at two or three times; the cupcake grows a reel for the round; the Red Queen takes over a reel at full height; Alice is the wild. Nothing here is decoration with a name attached.
The studio puts the hit rate at 38.04%, so the reels are rarely silent — but the amounts are modest. Then three rabbits land and it becomes a different game: fifteen spins, a board that grows underneath you, multipliers that combine rather than add. That is where the whole return lives.
Nine years on, this game still sells on one number — and that number is not settled. Which is the whole point: a title bought for its RTP is worth exactly the RTP your lobby runs, not the one a review prints.
Big Time Gaming's play-money build: no account, no deposit. Five reels, 16,807 ways in the base game and 248,832 once every reel reaches twelve rows.
Use the demo as you would the real thing: set a stake, count the spins before three rabbits land, and watch the board once cupcakes arrive. The wait is what to rehearse — the studio's hit frequency is 38.04%, but a third-party desk puts natural feature triggers at roughly one in 180 to 220 spins.
Four returns circulate for one game. The studio's own page publishes 96.42%; the review industry quotes 97.24%, 97.72% and 97.77%. Not four opinions about one build — and the studio's is the lowest.
Big Time Gaming prices the Feature Drop at 100 times your bet, falling each time a gold studio coin lands. Because that purchase is priced fairly, buying it at full price lifts the long-run return: the default configuration gives 97.24%, the bought-feature figure 97.77%.
Big Time Gaming's current game page prints 96.42%, a 38.04% hit frequency and a 17,416× bet max payout — the only machine-readable figures the studio publishes anywhere. UK desks meanwhile call 97.24% the default: OLBG records "only 1 RTP version available to UK online casinos", and Online-Slot that "the RTP rises to 97.77% when the Feature Drop is purchased at full price. This is not available in the UK though." Feature buys are not offered at UKGC-licensed sites — the reason is here.
Casino.Guru, LadyLucks, Gmblrs, PokerNews and Gambling.com all print 97.72%. Operators can be shipped more than one certified profile, which is why a review's figure and a lobby's figure can both be accurate and still differ. One UK desk puts it directly: operator versions vary more than usual here, so read the in-game panel.
PlayOJO — Gambling Commission account 39326 — prints 97.77% in the Game Info box on its own White Rabbit page and still describes the Feature Drop as usable: a configuration its British lobby does not run, on a page older than the rule, and 1.35 points above the studio's own figure. Which is why the panel in front of you outranks any review, including this one.

Computed from the published returns — ordinary cash play, so no wagering attaches.
On the studio's 96.42%, £1 a spin costs an expected 3.58p, so £100 looks indestructible on expectation alone. It is not: two hundred spins without a feature costs £200 at that stake. At £5 — the British ceiling for 25 and over — it is 17.9p a spin, so £100 covers roughly 559 spins. Blackjack at basic strategy runs about 0.5%, where £100 covers around 4,000 hands: slots cost more per unit staked and swing harder — see our payout-maths guide.
The spread in money: 1.35 points between the studio's 96.42% and the highest figure a UKGC operator prints — £6.75 on £500 of turnover. Which is why this page leads with the panel check, not a headline number.
Five reels at two to seven rows, 16,807 ways, and a feature that rebuilds the board while it runs.
Three scatters award 15 free spins. In the studio's words, every cupcake "splits into two new symbols, increasing the reel height by one" — up to twelve and 248,832 ways. A reel that reaches twelve triggers the White Rabbit Clock — up to twelve more spins — and becomes a Queen's Reel holding only Red Queens and wilds. Up to 75 free spins in total. In the base game the caterpillar blows up to four Bonus Wilds at ×2 or ×3, and those multipliers multiply together: three threes is twenty-seven.
The base game is not silent — Big Time Gaming puts the hit frequency at 38.04% — but the amounts are small: nine of the ten paying symbols top out below 2.1× for five. What you wait for is the scatter combination, estimated by a third-party desk at roughly one in 180 to 220 spins. Plan a spin count, not a session length.
Work backwards from the trigger estimate, not from your budget. A bankroll that buys fifty spins is only buying the base game — the part that pays least. At 20p, £50 is 250 spins and £100 is 500. With the GB game cycle floored at 2.5 seconds, an hour tops out near 1,440 spins: £288 of turnover at 20p, expected cost £10.31.
The studio ships an HTML5 build for mobile and desktop alike. The constraint is geometry, not performance: a twelve-symbol reel has to fit the screen a four-row reel did, so symbols shrink as the feature succeeds. Landscape gives the grid room. GB builds carry simpler controls — no autoplay, no turbo, no slam stop.
Big Time Gaming describes the Red Queen as deliberately dark and the Rabbit as stern rather than cute — drawn for adults, not a cartoon. In play, audio and frame do one job: a cupcake lands, the music steps up, the reel gains height. That is the signal the maths has changed under you.
Every figure is a multiple of total stake for adjacent symbols left to right. The £ column shows the return at a £0.20 spin.
Multiples of total stake. Corroborated by Casumo's own game page and a published third-party table, read 2 August 2026.
There are no paylines to count. A win is any run of matching symbols on adjacent reels from the left, so the routes change every spin as the reels resize — and again, permanently, each time a cupcake raises a reel. One disagreement worth naming: a third-party desk publishes the blue and green gems at four and three times for five; Casumo's own page states two times each, and the operator table is the closer source.
What each does, not just what it pays.
| Symbol | Where it lands | What it does |
|---|---|---|
| Alice — Wild | Reels 2 to 5 | Substitutes for paying symbols, never for the cupcake, rabbit or studio coin |
| White Rabbit — Scatter | Reels 2, 3 and 4 | Three in view award 15 free spins; pays nothing on its own |
| Caterpillar | Beside the reels, base game | Adds up to four Bonus Wilds at ×2 or ×3; the multipliers multiply together |
| Cupcake | Any reel, free spins only | The studio's wording: it "splits into two new symbols, increasing the reel height by one" — and it stays raised for the rest of the round |
| Studio coin | Base game | Cuts the Feature Drop price where it is permitted. No function at a GB site |
Ways are the product of the five reel heights.
| Reel height reached | Ways to win | Where it happens |
|---|---|---|
| 2 rows on every reel | 32 | The floor of the Megaways engine |
| 7 rows on every reel | 16,807 | Base-game ceiling — 7⁵ |
| Standard Megaways ceiling, for comparison | 117,649 | Six reels at seven rows — not this game |
| 12 rows on every reel | 248,832 | Free spins, all five reels fully extended — 12⁵. A reel reaching twelve unlocks the White Rabbit Clock |
Big Time Gaming publishes a max payout of 17,416× bet; UK lobbies print 10,000× (PlayOJO) and 1,300× (Paddy Power). All of these are a max game-round win — no separate max win per spin is published by anyone. Both labels appear together throughout this page.
White Rabbit was the first Big Time Gaming title to ship a buy-the-feature button — and in Great Britain it is the one part you will not find.
Big Time Gaming describes its own mechanic plainly: press the Bonus Buy icon "to purchase 15 Free Spins for 100x your stake" — a price that "is reduced every time the player gets a BTG coin". Casumo states the same 100× start. At a UKGC-licensed site the button is not there at all.
The Gambling Commission's Remote gambling and software technical standards set the rules every GB-licensed game build has to meet. RTS requirement 14A reads, verbatim:
"Gambling products must not actively encourage customers to chase their losses, increase their stake or increase the amount they have decided to gamble, or continue to gamble after they have indicated that they wish to stop."
Paying a fixed multiple of your stake to skip into a bonus round is the shape of thing that requirement is written about — at 100×, a 20p spin becomes a £20 commitment in one press. So the buy feature is not offered at GB-licensed casinos, while the game itself remains fully playable with the button removed.
The build you load at a UKGC-licensed site against the one international reviews describe.
| What you compare | GB-licensed build | Markets that permit feature buys |
|---|---|---|
| Reaching the free spins | Scatters only — three on reels 2, 3, 4 | Scatters, or buy at 100× falling with coins |
| Provider-listed RTP | 97.24% per the corpus; 96.42% on the studio page | Up to 97.77% with the feature bought at full price |
| Symbols, paytable, Extending Reels, Queen's Reel | Identical | Identical |
| Ways ceiling and max game-round win | 248,832 ways, cap unchanged | 248,832 ways, cap unchanged |
| Autoplay, turbo, slam stop | None — RTS 8, RTS 14E | Commonly available |
| Minimum time per game cycle | 2.5 seconds — RTS 14D | Operator and market dependent |
The summary is narrow: one route into the feature closes, and half a percentage point of theoretical return goes with it. Everything distinctive — the growing board, the Queen's Reel, the multiplying caterpillar wilds, the ways count — is the same.
If you came for a bonus buy, compare titles that reach their feature naturally. Twin Spin Megaways needs five scatters and is the strictest of the group; 5 Lions Megaways and Power of Merlin Megaways take the Pragmatic Play route to the same engine. The comparison section sets them side by side.
Five checks before your first spin, each one you can actually do.
1 · Set the stake in £, and set it for the wait
A GB lobby runs this from £0.10 a spin, with the ceiling set by Britain's age-tiered cap: £5 at 25 and over, £2 at 18 to 24. For this trigger pattern the practical band is the bottom of that range — at 20p, £50 buys 250 spins and £100 buys 500.
2 · Open the game-info panel before the first spin
Confirm two lines: the Return to Player figure and the ways-to-win range. Four figures circulate, from 96.42% on the studio page to 97.77% on a UKGC operator's — the configuration table tells you which build you have.
3 · Read the reel frame, not just the win line
Every added row changes the ways count, and that is what your next spin is worth. Watch the caterpillar in the base game, the cupcakes in the feature.
4 · Know how the feature arrives
Three scatters on reels two, three and four award 15 free spins. Cupcakes then raise reels permanently, up to twelve rows; a reel reaching twelve adds three to twelve more spins and becomes a Queen's Reel. With no buy button in GB, the scatters are the only route in.
5 · Set your own limits first
Deposit limits and reality-check reminders live in every GB-licensed account panel and take less time to set than ten spins take to play. GamStop covers every UKGC-licensed site at once. Then play the demo above with the same stake logic — identical maths, nothing at stake.

Paraphrased, anonymised themes from public GB-facing review threads and desks, read 2 August 2026 — a signal, not a verdict.
Called one of the highest-RTP Megaways titles available — a reputation built on 97.24%, which is not what the studio's own page now prints.
The Wonderland treatment is called distinctive rather than a reskin, and the expanding reels are named as the reason people come back.
The published maximum runs from 1,300× to 17,416× depending on where you read it — two UKGC operators alone print different numbers. The fact core lists them all.
Desks split on the label for the same game. With no single studio-published figure, the useful reading is the trigger pattern, not the word.
The base game is described as grindy: plenty of small returns, real money locked behind a trigger that can take hundreds of spins. Size the stake for it.
British players arrive from international reviews expecting a Feature Drop, then find the game runs without it. The reason, and what changes.

The positioning: the edge is the return plus the Extending Reels; the trade is trigger scarcity. A bigger ceiling costs roughly a percentage point of return — about £6 on £500 of turnover.
Every row holds a UKGC licence and is registered with GamStop. The third column is the one no rival carries: what that lobby prints on its own page.

Credit cards are not permitted for gambling in Great Britain. 4 · Bonus terms in one place — wagering multiple, weighting, cashout cap. 5 · The game-info panel — return figure and ways range, before the first spin.

Which RTP will I actually see if I open this at a UK casino?
Whatever the lobby's game-info panel says — that panel governs your play. The default GB configuration is 97.24%. Compare it against the configuration table.
Does the missing Feature Drop make the game worse value?
It changes how you reach the feature, not the symbol set, the ways count or the caps. The theoretical difference is 0.53 of a percentage point.
What stake makes sense for a £50 bankroll?
Work backwards: 10p to 20p gives you 250 to 500 spins, which is the horizon this trigger pattern needs. Set a deposit limit before you start.

Big Time Gaming's Alice-themed Megaways slot, released 25 October 2017: five reels, 16,807 ways base, 248,832 in free spins. The studio publishes 96.42% RTP; reviews quote up to 97.77% — check your lobby's panel.
At UKGC-licensed casinos carrying Big Time Gaming's catalogue. The table above lists five whose own White Rabbit page we opened, with each lobby's licence detail.
Four figures circulate. Big Time Gaming's own page prints 96.42%; the review industry quotes 97.24%, 97.72% and 97.77% — the last being the Feature-Drop figure PlayOJO prints. The configuration panel maps each to its build; your lobby's panel governs your session.
Big Time Gaming's buy-the-feature option: 100 times your bet to start, falling with every gold studio coin, takes you straight into the free spins. Not offered at GB-licensed sites, so British players land three scatters instead. What changes.
The studio publishes 17,416× bet. UK lobbies print less: PlayOJO 10,000×, Paddy Power 1,300×; global desks say 13,000×. All are a max game-round win — no max win per spin is published by anyone.
The studio shows a rating as a graphic with no text value, and the desks split high / medium. The pattern matters more: the studio puts the hit frequency at 38.04%, and a third-party desk estimates natural feature triggers at roughly one in 180 to 220 spins.
Yes — the demo at the top of this page runs the same maths, no account needed. Use it to rehearse the wait at the stake you would actually use.
It suits players who want a top-of-field return and can hold a bankroll across several hundred spins; short sessions and quick wagering clears far less well. The verdict section splits it.
It depends on the lever. On published return, White Rabbit Megaways is at the top of the mainstream field. On ceiling, Bonanza Megaways publishes 26,000×, at roughly a percentage point less return. The comparison section.
A licensed engine, not a quality mark: reel heights change each spin, so the ways count changes with them. That is more variance than a fixed-payline game, not more return. White Rabbit adds a second layer, growing reels permanently inside a feature round — which is why its ceiling of 248,832 sits above the standard 117,649.
