What does John have to say?

Wild Joker Stacks feels like a bit of an empty promise. The main gimmick here is the customization, but with only the highest settings offering any sort of decent experience, this core function falls short of what it aims to achieve. Its saving grace is the high max win amount, that can offer players a decent level of potential.

Wild Joker Stacks Slot Review

Coming up with yet another reason to dish out a classic fruit slot can be quite tough, but Yggdrasil and Boomerang Studios have managed to do just that. Wild Joker Stacks is a classic fruit slot that aims to capture the hearts of players around the globe thanks to its customisable elements and incredibly high potential.

The theme is something we’ve seen a hundred times before, so there’s nothing that fresh about it. While others have tried to update the classic look and give it a more contemporary feel, Boomerang Studios seem to have gone the other way. The visuals are quite dull and dated, giving the slot a cheap finish.

But looks can be deceiving and hopefully in this case they are! Read through our in-depth video slot review to learn all you need to know about Wild Joker Stacks!

Wild Joker Stacks Bonus Features

Perhaps Wild Joker Stack’s greatest trick lies in the fact that it allows players to customize their experience. This level of tailoring is quite rare in video slot and the potential to build your own experience can seem quite enticing. In this case, players can choose the number of rows present in-game, as well as the multiplier level. Rows can vary between 3-5 and multipliers between x2-x4. This also affects that games volatility and RTP. While the concept may hold some ground, the reality is that the game is only really worth your while when both options are turned to the max setting.


The titular Wild Joker steps in to substitute itself for any paying symbols that could form part of a winning combination. Their multiplier values are determined by the player, ranging between x2 to x4. Additionally, the symbols get an upgrade of their own in the slot’s Free Spins bonus.

Scatter Symbol

3 or more Scatter symbols will open your way to free spins, with a 9 bonus rounds on the house. The symbols themselves also carry their own value, with 5 of a kind worth 100x your current stake.

Free Spins

In Free Spins, the slot plays out in pretty much the same way as the base game, expect for one crucial factor… the titular Wild Joker Stacks. Here, Wild Multipliers are doubled, meaning that they can have the highest setting of x8. Additionally, Wilds land in stacks, opening the door for the slot’s biggest wins possible. More free spins can also be triggered in-game with more Scatter symbols.

Wild Joker Stacks Jackpot

There is no dedicated jackpot feature in Wild Joker Stacks, although the slot’s maximum win amount can still land you with a 28,200x haul.

RTP & Volatility

Volatility and RTP are both determined by the player’s choices. Depending on the chosen Wild Multiplier, volatility can range from low to high, while RTP can go from 95.6% to 97.78%. Although these choices are in place, the game is only really balanced and worth your while when all elements are turned up to the highest setting.

Wild Joker Stacks on Mobile

With full mobile compatibility, you can enjoy Wild Joker Stacks on the go and on any device of your choosing. We feel it’s worth mentioning that even with full compatibility, the slot doesn’t translate very well in a portrait viewing mode, as its problematic design favours the landscape setting.
