AvatarUX: Slots With Growing Reels
AvatarUX is the studio behind PopWins, the award-winning mechanic where winning symbols “pop” and split into more symbols, growing the reels with every win. Since launching its first game on the Yggdrasil network in 2019, it has become one of the most recognizable innovators in online slots, with hits like CherryPop, LooneyPop and ReefPop and max wins of up to 50,000x.

AvatarUX Review
The Studio Behind PopWins
AvatarUX launched its first game on the Yggdrasil network in 2019, and a year later released CherryPop, the slot that introduced PopWins. The idea is simple: when a symbol is part of a win, it “pops” and is replaced by two new symbols, so the reel grows taller. More symbols means more ways to win, and a single spin can keep chaining wins as the grid expands.
PopWins became the studio’s calling card, and AvatarUX has built a whole family of mechanics on top of it: MultiPop, StickyPop, Xpops (where wins pop into 1 to 4 new symbols, as in GemPops), the ZapReel reward reel above the grid (LooneyPop, Floridaman) and Infinity Stacks. Many of its slots also include a gamble wheel before free spins, where you can risk your bonus for more spins, taller reels or a higher starting multiplier.
An Award-Winning Innovator
The industry has noticed. AvatarUX won Game Innovation at the CasinoBeats Awards in 2021, Slot Supplier Rising Star at the EGR Awards in 2022, Game Mechanic of the Year at CasinoBeats in 2023, and Slot Game Developer of the Year at the SlotsWise Awards in 2024. It also runs its own remote gaming server, launched in 2021, and distributes through partners including Relax Gaming, Light & Wonder, Digitain and Reevo.
What to Expect When You Play
AvatarUX slots are built for big swings. Most of our picks are high or “super high” volatility with max wins of 10,000x to 50,000x, so expect long quiet stretches broken up by explosive bonus rounds. Floridaman is the notable exception: it’s rated low volatility yet still has a 20,000x ceiling.
One thing to watch: AvatarUX games come in several RTP versions, typically 96%, 94% and a lower version of around 86–90.5%, and the casino chooses which one to run. The difference is significant, so open the game’s info or paytable screen to check the RTP before you play.
Licensing & Fairness
AvatarUX (operating as Epic88) holds a B2B license from Sweden’s Spelinspektionen (2023) and a Class 2 license from Romania’s National Gambling Office (2025), and received a Malta Gaming Authority recognition notice in July 2025. Those are strict regulators, so the studio’s games meet demanding certification standards.
Where to Play AvatarUX Slots
AvatarUX is widely stocked across European, crypto and international casinos, though which games you’ll see depends on the casino and your location.
BitStarz stocks AvatarUX titles like LooneyPop and CherryPop Burst among 3,500+ games from over 60 providers. Through our link, new players pick up 20 no deposit free spins with no code to enter, and crypto withdrawals normally arrive within minutes. Our BitStarz Casino review covers the rest.
You’ll find AvatarUX at many other crypto and international sites as well. Because both the game list and the RTP version can differ, search for “AvatarUX” in the lobby and check the RTP in the game’s info screen.
Using no deposit bonuses on AvatarUX slots: these are high-volatility games, which isn’t ideal for clearing wagering on a small bonus balance: a $20 free chip can disappear quickly between big hits. If you’re playing through a no deposit bonus, a lower-volatility option like Floridaman is the better fit. Buy Bonus is usually disabled while you’re playing with bonus money.

What is PopWins?
PopWins is AvatarUX’s signature mechanic. When a symbol forms part of a win, it “pops” and is replaced by two new symbols, making the reel taller.

Is AvatarUX a legitimate provider?
Yes. AvatarUX holds licenses from Sweden’s Spelinspektionen and Romania’s National Gambling Office, received a Malta Gaming Authority recognition notice in 2025, and has won several major industry awards. It’s still worth confirming that the casino itself holds a license.
What is the RTP of AvatarUX slots?
AvatarUX slots are available in multiple RTP versions: usually 96%, 94% and a lower option of around 86–90.5%. The casino decides which version to offer, so always check the RTP in the game’s info screen before you play.
