This overview of White Rabbit slot RTP versions, bonus rules and Australian online gambling law begins with a detail that most reviews overlook. The return of the game varies based on the method used to access the bonus, and Big Time Gaming's own documents list multiple figures.
Other sources cover the basics well. White Rabbit is a Megaways slot from Big Time Gaming based on Alice in Wonderland, released on 25 October 2017. It features five reels, a free-spins feature where reels grow, and up to 248,832 ways to win during that feature.
Where White Rabbit stands in Australia
According to the Interactive Gambling Act 2001, online casino games, such as slots and online pokies, may not be provided to individuals located in Australia. This rule is valid regardless of whether the provider is offshore or based in Australia, and such services may not be advertised here.
Players do not commit these offences; the providers do. ACMA blocks the websites of illegal offshore operators.
Since no online casino can obtain a licence for Australian players, no RTP minimum or stake cap for online slots exists in Australia. The following figures represent the game as shipped by Big Time Gaming. They do not represent a version you can lawfully play online from Australia.
The RTP versions
Different figures are provided by the sources:
| Source | Condition | RTP |
|---|---|---|
| Provider game page | Single listed figure | 96.42% |
| Game help sheet | Playing without buying Feature Drop | 97.24% |
| Game help sheet | Buying Feature Drop at full price | 97.77% |
| Game help sheet | Feature Drop price has fallen to zero | 97.24% |
Depending on the amount paid, the game help sheet puts the range at 97.24% to 97.77%. The provider game page lists 96.42%, which is a separate figure, and these two should not be combined into a single value.
RTP can differ across game versions. The figure that applies is the one found in the game help sheet loaded within the version you are viewing.
Some reviews cite 97.72% as though it were a single fixed RTP. No provider document mentions that figure. The game help sheet provides a range linked to the purchase price.
Feature Drop
The Feature Drop button displays an initial cost. This price decreases every time a BTG coin symbol appears. Once the cost hits zero, the feature activates automatically.
You're able to purchase the feature at any time for the current listed price. An immediate purchase at the full cost follows the 97.77% figure. If you wait for coins to reduce the price to zero, it lands you at 97.24%.
The game help sheet doesn't list a specific multiplier or purchase cost. It also mentions that Feature Drop might be unavailable if:
- a casino or jurisdictional limit is exceeded by the price
- the feature buy is disabled
If it's disabled, the player simply doesn't have it as part of the game. In some jurisdictions, Autoplay might also be unavailable.
The base game
Up to seven symbols appear on every reel, resulting in a maximum of 16,807 ways (7 × 7 × 7 × 7 × 7). Wins pay for matching symbols on adjacent reels starting from the left, regardless of the height of the reels.
The Caterpillar can randomly place up to four Bonus Wilds. Each one applies a 2x or 3x multiplier to the wins it forms part of. Bonus Wilds replace all symbols except Feature Drop symbols and Scatters.
The game pays only the largest win for any winning combination, and these totals are then summed. For instance, if a combination is eligible for a four-symbol and a three-symbol win, you get the larger payout. This figure is then added to all other wins from the spin.
Free spins, Cupcakes and Queen's Reels
15 free spins are triggered by three Scatters. Scatters only appear on reels 2, 3 and 4 in the base game. Neither Scatters nor Feature Drop symbols appear during free spins. Every free spin uses the stake that triggered the feature.
Between 5 and 7 symbols start the feature on each reel, and this height carries over between spins. A Cupcake on a reel is replaced by two symbols, so that reel grows by one.
According to the provider's game page, Cake symbols "add two extra symbols". The game help sheet describes this same event more exactly. The Cupcake's own position becomes two symbols, so the net gain is one row. Wins are paid once the extra symbols are shown.
A reel can grow to 12 symbols, creating a maximum of 12⁵, or 248,832 ways. Two things happen when a reel reaches 12:
- It becomes a Queen's Reel, containing extra Red Queens and Wilds.
- The feature retriggers and gives 3 to 12 more spins.
The feature can retrigger up to five times in total.
The small print
The provider's rules are listed here, and they can vary across different versions of the game.
- Stalled rounds. Bets are refunded and a game is cancelled if it's left in progress for over 30 days. If a free-spins round isn't finished by then, you get the bet back instead of the feature continuing.
- Malfunction. All plays and pays are voided if a system malfunction occurs. No win shown during a fault is owed.
- Disconnection. No distinct rule for a dropped connection is listed in the game help sheet. Other than the 30-day cancellation, it contains no specific rule for a bonus that isn't finished.
- Maximum win. No cap is published in the rules, and they don't state what happens if a win cap is reached.
What the provider doesn't publish
A volatility rating, a stake range and a maximum win aren't provided on the provider game page or the game help sheet. For free play, the game page's Play Game button goes to BTG's Play For Fun site, which asks you to sign in with Facebook or Google first. The provider game page mentions play on desktop and mobile.
Maximum wins listed on third-party pages contradict each other. These figures range from 25x to 17,420x the total bet, and 13,000x is also mentioned. None of them are provider-confirmed, so treat any single number with caution.
Gambling is for adults. If you gamble in any form, set your limits before you start and keep to them.
