Purrrminator Slot RTP, Details & Wager Limits
You’ll see the Purrrminator slot game running on a 6-reel, 4-row setup, but instead of standard paylines like most online slots, it goes with a connected ways system. That means wins come from lining up at least three matching symbols in adjacent spots, starting from the left.
Select the ‘+’ or ‘-‘ buttons below the reels to tweak your bet, with choices running from 10p to £200. It’s a pretty decent spread compared to other online free slots. If you turn on Auto Spin, the game runs on its own for 10 spins or more—even indefinitely. You can also set limits for it as long as you’re playing in non-UK Purrrminator casinos.
The Purrrminator RTP of 96.1% puts it a little above the average for new online slots. Then, based on its medium-to-high volatility, I expected a mix of steady wins and decent-sized payouts—and that’s exactly how it played out.
While testing the Purrrminator demo on some of the best online slot sites, I saw firsthand what the Reverse Avalanche feature could do. It’s your best shot for the 5,000x Purrrminator max win since it helps keep winning symbols locked while the reels keep going.
Purrrminator Theme—The Cyberpunk Alley Where Cats Rule and Dogs Drool
Relax Gaming has done a remarkable job bringing Purrrminator’s dystopian pet-filled world to life. You’re thrown into a cartoonish, worn-down cityscape with cracked walls, exposed piping, and makeshift laundry lines. To the left of the reels is a cat controlling a mechanised dog with a dice-covered chest, while on the right is a group of hardened canines watching from the shadows who come and go as they please.
The audio also leans heavily into a playful style with plenty of effects, like the barking dogs.
The symbols have a rugged look to them, which fits right into the game’s scrappy theme. The lower-paying ones are lumpy-shaped spades, clubs, diamonds, and hearts—a familiar sight in many of the best online slots. On the other hand, the higher-value icons are five different dogs, each looking more fierce than the last. Then, there’s the free spins scatter, which also doubles as a wild.
Here’s the full breakdown of all symbols and their payouts:
| Symbol | Payouts/Info |
|---|---|
 Blue Spade | 3 to 6+ = 0.1 to 0.4x the stake |
 Green Club | 3 to 6+ = 0.1 to 0.4x the stake |
 Yellow Diamond | 3 to 6+ = 0.2 to 0.5x the stake |
 Red Heart | 3 to 6+ = 0.2 to 0.5x the stake |
 Chihuahua (Blue) | 3 to 6+ = 0.3 to 0.6x the stake |
 Basset Hound (Green) | 3 to 6+ = 0.3 to 0.6x the stake |
 Poodle (Purple) | 3 to 6+ = 0.4 to 0.7x the stake |
 Bulldog (Yellow) | 3 to 6+ = 0.5 to 1.5x the stake |
 Doberman (Red) | 3 to 6+ = 0.7 to 3x the stake |
 Wild | Bonus | Substitutes for all paying symbols & triggers free spins |
Purrrminator Mobile Slot
I played Purrrminator on my iPad and Android phone, with everything performing consistently well across mobile casinos thanks to its HTML5 build. I particularly appreciated how the layout was fully optimised in portrait mode, with the reels shifted to the top and the menu below them. The landscape layout looked a lot like the desktop version, but the reels felt a bit too small for my liking. Also, I preferred to hide the toolbar since it took up quite a bit of space.
Purrrminator Bonus Features
Purrrminator’s bonus features revolve around its Reverse Avalanche mechanic and expanding free spins. And if patience isn’t your thing, you can skip the wait through the bonus buy feature.
Reverse Avalanche Feature
The Reverse Avalanche Feature triggers when 3+ connected symbols land, and it locks winning symbols on the grid—wilds, bonus symbols, and the highest-paying winning symbol. Everything else disappears, and the remaining symbols drop down, making room for new ones. If only one symbol creates a win, it becomes the kept symbol, and no further collections occur.
Each new drop can introduce additional features like symbols with arrows that expand up or down, wilds, bonus symbols, or blockers. The process repeats until no more valid symbols appear or the grid fills up with blockers. If multiple winning symbols are present, the highest-paying one is kept, and others contribute to the win collection but disappear.
Free Spins
If you land 3 bonus symbols in the base game, you can get between 5 and 20 free spins. With 4 scatters, the lowest option (5 spins) is removed, so you’ll get between 7 and 20, and if you hit 5, you’ll get at least 9 up to 20 spins. All rounds take place on an enlarged 6×5 grid.
Also, special symbols can land during free spins that expand to cover an entire reel and increase potential payouts.
Feature Buy (Not Available in UK Online Casinos)
With the Buy Feature, you can purchase entry into the free spins round instead of waiting to trigger it naturally. It costs 50x your regular bet and guarantees at least 3 bonus symbols with an RTP of 96.5%.
Purrrminator Verdict: High-Tech Cats, Expanding Reels, and a Risky Edge
I spent a good chunk of time testing Purrrminator, and while it’s not the most feature-packed slot out there, what it does have works very well.
The Reverse Avalanche takes a little getting used to since it’s not the usual cascading wins where everything drops in place. Instead, it creates a unique flow where only key symbols stick while the rest clear out. It’s almost like other games’ hold-and-respin mechanics or sticky wins. The cartoon cats vs. dogs theme does add some charm to it, too, though the gameplay can sometimes feel a bit slow.
Is it Relax Gaming’s most innovative slot? Maybe not. Yet, if you’re after something mechanically different, with a bit of strategy in how symbols stick and expand, I’d encourage you to try it yourself. You can start with the free demo first.
