The main game uses a 54-segment wheel containing the regular numbers 1, 2, 5 and 10, alongside segments for the various bonus features.

The number distribution is not equal. Number 1 occupies 21 segments, number 2 appears on 15, number 5 has five and number 10 has four. The remaining sections are devoted to the bonus and Mystery outcomes, meaning the more valuable results naturally occupy considerably less space on the wheel.

Once betting closes, the presenter spins the physical wheel and the pointer determines the winning result. Back a number and the wheel lands there and you will receive the corresponding payout, while correctly backing a bonus position gives you access to that feature.

It is a familiar money-wheel formula and that is probably a good thing because there is considerably more to learn once the bonuses start appearing. The base game gives you an extremely simple foundation and lets the features provide most of the complexity.

I also like being able to see the entire wheel before each spin. When it starts slowing down near a cluster containing bonus segments, there is a natural bit of anticipation as the pointer bounces between something interesting and another visit from number 1.

The four standard bets are 1, 2, 5 and 10, paying according to their respective values when the wheel lands on them. There are then separate betting positions for 2 WonderSpins, 5 WonderSpins, Magic Dice and Walterspins.

That gives Adventures Beyond Wonderland a good mixture of frequent lower-paying results and considerably less frequent feature bets. You can cover several positions if you want more of the wheel working for you, although every additional selection is naturally another wager rather than free insurance against missing the result.

There is an important RTP difference between the bets too. Published figures put the standard number positions between approximately 96.58% and 96.70%, with number 10 at the upper end, while 2 and 5 WonderSpins are around 96.67%. Walterspins is noticeably lower at approximately 96.11%.

That is worth knowing because the most entertaining-looking bet is not automatically the one giving you the strongest theoretical return.

Even in Wonderland, the maths eventually catches up with you.

Walter the Caterpillar can randomly add a multiplier to one of the regular number positions before the main wheel result is determined.

It is a relatively simple modifier, but it gives the ordinary number bets something extra to watch for. Instead of every spin being entirely dependent on where the wheel stops, a normally unremarkable number can suddenly become considerably more attractive when Walter decides to improve it.

I like having a modifier operating around the main wheel because Adventures Beyond Wonderland's biggest features naturally attract most of the attention. The numbers need something of their own to prevent them feeling like the boring bits sitting between bonus rounds, and the additional multiplier provides exactly that.

Walter apparently understands that even Wonderland occasionally needs a price boost.

The Mystery segments are particularly interesting because they do not behave like ordinary betting positions. When the wheel lands on Mystery, the resulting feature can affect active players regardless of which normal position they originally backed.

The outcome can provide an instant cash prize, multiplier or another wheel spin with enhanced values, depending on the Mystery result.

I like this because it gives the wheel a couple of positions that remain interesting even when you have not specifically backed a named bonus. Most game shows divide the wheel very clearly between "your result" and "somebody else's result", whereas Mystery can suddenly make an otherwise irrelevant segment important.

It also suits the Wonderland theme perfectly. If any game can justify having a couple of wheel segments where nobody is entirely sure what is about to happen, it is probably this one.

Magic Dice takes the action away from the main wheel and into a board-style bonus game using physical dice.

Potential multiplier prizes are arranged across the bonus board and the dice determine how the feature develops, with players able to make choices during the round rather than simply sitting back and waiting for a multiplier to be revealed.

That is what makes Magic Dice particularly effective. The game remains random, of course, but giving players something to select creates considerably more involvement than a bonus where an animation simply plays until the final prize appears.

It also provides a complete change of pace from the main game. You have spent the previous rounds watching a large physical wheel, and suddenly you are inside a Wonderland board game with dice determining where the feature goes next.

For me, that is exactly what a game-show bonus should do. If I have waited for a relatively uncommon bonus segment to land, I would rather it actually take me somewhere different.

Landing 2 WonderSpins after backing the feature awards two spins of the special WonderSpins wheel.

This is separate from the main game wheel and uses Wonderland characters and multiplier values to determine the resulting prize. The bonus therefore retains the wheel concept while changing both the presentation and the potential outcomes enough to make it feel distinct from an ordinary round.

Two spins obviously do not give the feature much time to develop, but they provide the more frequently available route into WonderSpins and give you a couple of chances to put together something worthwhile.

The real attraction is seeing the main studio disappear and the game move deeper into its Wonderland theme. It feels like you have actually reached a bonus rather than simply being awarded another spin of exactly the same wheel.

5 WonderSpins uses the same underlying bonus system but provides five spins rather than two, giving the feature considerably more room to develop.

Unsurprisingly, this is the WonderSpins result I would rather see. Five attempts allow multiplier combinations and bonus effects more opportunity to produce something interesting, while the longer feature makes the relatively rare trigger feel more substantial.

There is also something satisfying about knowing you have secured several spins before the first one even begins. With the two-spin version you are barely through the looking glass before somebody starts showing you the exit.

Five WonderSpins lets you have a proper look around.

Walterspins is a modified version of WonderSpins featuring Walter the Caterpillar and an additional multiplier mechanic.

The feature begins by introducing a hidden multiplier that can then affect the WonderSpins outcome, giving the bonus another layer beyond the standard version. You are still dealing with the familiar bonus-wheel structure, but Walter's involvement means there is additional potential attached to the spins.

Mechanically, I like it. It takes an established bonus and adds enough to make the rarer Walterspins trigger feel different rather than simply awarding another quantity of ordinary spins.

The slightly awkward part is the maths. Despite looking like one of the premium features, published figures put Walterspins at around 96.11% RTP, below the other main betting positions.

Walter gives with one hand and apparently checks the house edge with the other.
