Critter Pop: Slot Overview

Long before CGI became the default, plenty of entertainment relied on puppets. A famously quirky example was the TV series The Muppet Show. Among its recurring segments was Pigs in Space, a Star Trek spoof featuring Captain Link Hogthrob, First Mate Piggy, and Dr Julius Strangepork as they roamed the cosmos aboard the Swinetrek. It’s easy to imagine that, in some small way, Pigs in Space may have helped spark an idea for AvatarUX when creating their animals-in-space slot, Critter Pop.

True to its title, Critter Pop joins AvatarUX’s PopWins lineup of online slots. The action unfolds in space, with swirling gases, planets, and stars setting a cosmic backdrop for a cast of critters. These creatures appear as the premium symbols on an expanding grid that begins in the base game as a 5-reel, 3-row layout. Around the grid (jurisdiction dependent) sits a selection of controls, including an Ante Bet, Bonus Buy, plus various info and settings. Bets can be set from as little as 20 p/c per spin up to $/€100. Activating the Ante Bet option increases the stake by 25% whilst doubling the chance of triggering free spins in return. Critter Pop is a highly volatile slot with a theoretical return to player of 96.03%.

When the grid is at its default 5×3 size, there are 486 ways to win, with ways paying left to right and also right to left. That means three or more matching symbols on consecutive reels can start from either edge of the grid, though five-of-a-kind wins only pay from a single side. Low symbols are card ranks 10-A, paying 1-1.5x the bet for five of a kind, while six animal symbols serve as the higher pays, awarding 2-6x the bet for five of a kind. The top two symbols are the tiger and the mammoth, which matters during the Rewards Reel stage explained later. Wild symbols can replace any regular paying symbol, but they only show up during free spins.

Critter Pop: Slot Features

Alongside the signature PopWins engine, Critter Pop also brings a free spins bonus featuring several possible reel modifiers, plus the Base Game Unlock.

PopWins

Whenever a winning way lands, each involved symbol pops off the grid and is replaced by two new symbols, boosting both the number of ways and the reel height. If this creates another win, PopWins activates again, repeating for as long as new wins keep forming. In the base game, reels can grow up to 6 positions high, where there are effectively 15,553 ways to win, or 8 high during free spins, where 65,536 ways are in play (both ways). Once reels hit their maximum height, any popped symbols are replaced by only one symbol instead.

Base Game Unlock

During the base game, if the reels expand fully to 6 symbols high, the Base Game Unlock feature awards 2 free spins on the enlarged reel-set.

Free Spins

Hitting 3, 4, or 5 scatter symbols in the base game launches free spins, starting with 2,048, 6,250, or 15,552 starting ways on a 5×4, 5×5, or 5×6 grid, respectively. Before the free spins begin, the game runs a Rewards Reels sequence first. A single spin occurs where players may pick up extra free spins, a higher starting win multiplier, greater win multiplier increments, random 2×2 symbols, random 3×3 symbols, random wild symbols, tiger symbol multipliers, and mammoth symbol multipliers. After this spin, anything awarded by the Rewards Reels is carried over to free spins.

While the free spins feature is running, reels do not reset back to their initial size; instead, they fall to the lowest reel height achieved on the current spin. For instance, if the reels climb to 7-7-7-7-8 high, they drop to 7-7-7-7-7. If every reel reaches 8 symbols high, players receive +2 free spins and +x2 to the multiplier, and the grid stays at that height for the rest of the feature. The win multiplier starts at x1 or higher depending on the Rewards Reels outcome. It increases after each winning cascade and does not reset between free spins.

Buy Bonus

Where offered, the Buy Bonus button provides three ways of buying free spins. Prices are 125x for the Buy Bonus, 250x for the Buy Bonus Plus, and 500x for the Buy Bonus Max, with starting ways to win of 2,048, 6,260, or 15,552, respectively. In theory, paying more should translate into stronger rewards heading into the free spins round.

Critter Pop: Slot Verdict

At first glance, Critter Pop’s “animals in space” premise can feel a little out there, yet animals genuinely played a role in preparing the way for human space travel. It’s worth pausing to recognise the courage of critters such as Laika, Belka and Strelka, who helped open the door for the Russian Cosmonauts who came after. And then there was Ham, the American chimpanzee—who, judging by some of the footage, didn’t seem to enjoy his suborbital trip much at all. These animals didn’t volunteer; they were strapped into rockets and launched to see what would happen. RIP, you brave wanderers of the firmament.

Players, however, can decide whether to launch Critter Pop, so it’s worth weighing up what it offers. Theme-wise, it doesn’t have the polished cohesion seen in newer titles like MonkeyPop, RagingPop, or CherryPop Deluxe. The unusual pairing of critters and outer space feels more like an experiment, which could be equally appealing or off-putting depending on taste. After some playtime, the contrast between characters and setting fades a bit, making it easier to focus on how the slot actually performs.

Away from the bonus, gameplay largely revolves around popping winning symbols, expanding the reels, and increasing ways, with the occasional chance of triggering the two free spins reward when the grid reaches its maximum. Since the Base Game Unlock probably won’t land very often, the base game can feel somewhat repetitive. The bonus round is where PopWins really gets to show off, thanks to the modifier-granting potential of the Rewards Reels spin. With the right luck, wins up to 20,000x the bet can happen.

Critter Pop is a dependable PopWins entry with a slightly unconventional theme mix. It may not be the absolute pinnacle of PopWins slots, but players who enjoy this format should find plenty to like, and bonus buyers may be drawn in by the possible modifiers delivered via the Rewards Reel.
