Wild Joker Stacks is an online slot developed by Boomerang Studios. It’s a medium volatility slot with an RTP of 97.78% and a top win of x28,200. The slot has 5x3 reels and 259 paylines. Features include free spins, wild joker multipliers and the option to expand the reels.
Wild Joker Stacks is unusual in the world of online slots due to its unfixed reels. Players can adjust the size of the reels all the way up to 5x5, generating more ways to win. Wilds are customisable too, and it’s possible to choose the size of the wild multiplier before each spin.
As you can tell, Wild Joker Stacks departs from the traditional formula in quite a few ways. The symbols are more familiar however, and will be instantly recognisable if you often play fruit machine themed slots.
A lucky number 7, a golden bell and some cherries are the highest paying symbols. They appear on the reels along with an assortment of fruits and bar symbols. A diamond bonus symbol awards free spins, and special wilds with an attached multiplier can boost your winnings considerably.
Not only are there up to 259 paylines, but the Connecta Ways system offers you even more chances to win. Symbols only have to touch to form winning combinations, which opens up a whole host of opportunities.

Theme, Graphics & Soundtrack
Wild Joker Stacks might come with a lot of innovative gameplay features, but it still retains a classic slot theme. This means that all the classic fruit machine symbols are present and correct.
The colour palette of purples and golds gives this slot a luxurious aesthetic, and symbols like the golden bell are particularly sumptuous. Symbols glow around the edges with a soft golden light that makes them appear all the more decadent.
The only complaint that we have involves the music. Although the laid back tune is in keeping with the overall design, the loop is much too short and the music can become repetitive during extended play.
Wild Joker Stacks RTP & Volatility
Wild Joker Stacks has an above average RTP of 97.78% and a top win of x28,200. Even with that generous RTP, though, big wins remain uncommon and will always require patience.
How to play Wild Joker Stacks
We’ve put together this quick guide to help you through your first few spins.
1. Once the game has loaded, open the main menu by pressing the “i” button. Here you can see the paytable, read about the game rules and get to grips with the bonus features.
2. Wild Joker Stacks' reels are adjustable. You can alter their size up to a maximum of 5x5 by pressing the grid icon (it’s the three lines near the top right of the screen).
3. Wild symbols come with a multiplier that starts at x2, but this can be altered too. Press the wild icon at the bottom right of the grid to adjust the multiplier up to a maximum of x4.
4. Use the “total bet” box to adjust the size of your wager.
5. Autoplay is located on the left-hand side of the screen. You can set autospins up to a higher than average 500, but since these don’t come with loss/win limits, you’ll have to watch your balance.

Wild Joker Stacks bonus features
As you might expect from a slot with so many innovations, Wild Joker Stacks includes some excellent bonus features.
Since these can prove lucrative, we’ll take a more in depth look at how they work.
Wild Joker Bet
Wilds come with a multiplier, and players can adjust its size up to a maximum of x4. It’s important to remember, however, that the higher the multiplier, the larger your wager becomes.
Players can add rows to the bottom of the grid, increasing its size up to a maximum of 5x5. Much like the Wild Joker Bet, however, this also increases your wager.
A classic and much simpler feature, the player earns a free spin by landing 3 or more scatter symbols. Although a single free spin might not seem like much, your current multiplier is doubled, which can lead to some hefty winnings with the right amount of luck!
If ever we were worried that online slots are becoming a little samey, Wild Joker Stacks proved us wrong. It’s packed full of innovations and exciting features, and we have to commend Boomerang Studios for taking so many risks, all of which have paid off!
We loved how customisable this slot is. Adjusting the size of the grid and multipliers gives the player genuine control over their experience, and means that every play through will be different.
Wild Joker Stacks is a fantastic achievement. It looks great, plays smoothly, and manages to bring some completely new features to the age old formula of online slots!
