HippoPop (AvatarUX) – the PopWins mechanic is an excellent formula

And why should they stop releasing these fantastic slots? Many players love these. The PopWins feature is intriguing and striking.

HippoPop has many similarities with the other PopWins slots, but there are some subtle differences.

The theme is lovely: it’s set on the Amazonian landscapes, and you see love adorable wild animals. The artwork is creative and has neon-lit symbols. Gorgeous!

AvatarUX’s PopWins mechanic works pretty straightforward: a winning symbol “pops” and is replaced by two new symbols (instead of one) in the next free re-spin.

It allows the reels to expand up to 8(!) symbols in the free spins. If everything goes your way, you can end up with a scorching 65,536 ways to win.

The slot has, like most other PopWins slots, an inhumane win potential. The max win is 48,150x the bet, making it a “super” high variance slot.


Number of paylines: Up to 15,552 win ways in the main game and 65,536 win ways in the free spins

RTP and variance: 96.10%, Super high variance

Maximum win: 48,150 x the bet or  $€1.6 million

Betting range: $€0.20 – $€40

Bonus features: Free spins, Buy a Bonus feature

Casino Hipster verdict: Hot. The PopWins mechanic is fabulous, and the win potential is massive

Gameplay and Features

The slot starts with 5 reels with 3 symbols each, which is in line with the other PopWins slots.

Thanks to the PopWins feature, the reels can expand up to 6 symbols (“6-high”) in the main game and 8 symbols (“8-high”) in the free spins bonus game.

The PopWins feature works like win all ways slots do, and (also like all PopWins slots) you can win both ways (therefore from left to right and also from right to left).

If everything goes your way, you can have up to 15,552 win ways (calculated as 2x6x6x6x6x6=15,552) in the main game.

The Flamingo, Panther and Zebra are the high-paying symbols, and the medium-paying symbols are the Frog, Tucan and Fish. The lows are the J, Q, K and A.

The Golden Hippo is the so-called “super-high” paying symbol and is (obviously) the most lucrative symbol.

 How do you win the free spins?

You trigger the free spins if you manage to get all reels at 6-high in the main game. Alternatively, you buy the free spins with the Bonus Buy feature, where you get straight access to these after paying 85x the initial bet.

You win 5 free spins, but it’s possible (like with the other PopWins slots) to play with the Gamble Wheel and aim for more free spins. It’s possible to increase free spins with 2 or 4 additional free spins with the first gamble and afterwards with 2 or 5 free spins with the second gamble.

If you’re fortunate, you can end up with 14 free spins.

The free spins

The most important advantages of the free spins are:

  • Reels can become 8-high (rather than 6-high), thereby increasing the number of win ways to 65,536
  • You benefit from a total multiplier that can be as high as 10x at the start of the free spins and increase after each win.
  • The Golden Hippo’s (the super high-paying symbols) each get an x2, x3 or x4 multiplier once the reels are 6-high, 7-high or 8-high

If all reels are 8-high, you gain an additional two free spins.

The recipe for an epic win is to build up a massive multiplier, get all reels at 7-high or even 8-high and afterwards get a great winning combination with the Golden Hippos (with the x3 or x4 multiplier). In that case, your win is likely to be in the thousands of times the bet!

HippoPop slot: the payout rate (RTP) is 96.10%

The Return to Player of HippoPop is 96.10%, and it’s around the average RTP of all online slots.

HippoPop slot: the variance (volatility) is “super” high

According to AvatarUX, we’re talking about a “super” high variance slot.

Given the monstrous maximum win of 49,150x the bet, I guess it doesn’t surprise us that wins of thousands (or even tens of thousands) of times the bet is possible.
