Rules and Gameplay

Dive into the lush, vibrant world of the HippoPop slot, a game that brings the jungle to life right before your eyes. Developed by AvatarUX Studios, this slot takes you on a wild adventure with its unique PopWins mechanic. Initially set on a 5×3 grid, the game starts with 243 ways to win, but thanks to the innovative gameplay, this can drastically increase. Each winning combination pops and is replaced by two new symbols, potentially expanding the grid and increasing the number of winning ways. This dynamic gameplay keeps you on the edge of your seat, as each spin can lead to unexpected expansions and wins.

Bonus Features

The HippoPop slot is packed with exciting bonus features that promise to enhance your jungle journey:

  • PopWins Mechanic: This feature is at the heart of the game, where winning symbols pop and are replaced by two new ones, potentially increasing the grid size and win ways.
  • Free Spins: Achieving maximum grid expansion triggers the free spins round. Players start with 5 free spins, which can be gambled for more spins, up to 12, with a risk of losing them all.
  • Progressive Multiplier: In the base game, fully expanding the grid activates a multiplier that increases with each consecutive PopWin, adding a layer of excitement to your spins.
  • Expanding Grid: During free spins, the grid can expand further, up to 5×8, significantly increasing the potential win ways and boosting the game’s excitement.


Immerse yourself in a world where symbols come to life, each adding a piece to the HippoPop story:

  • Low-Pay Symbols: The traditional J to A symbols, designed with a jungle flair.
  • Medium-Pay Symbols: Vibrant representations of fish, birds, and frogs, each bringing the jungle’s melody to the reels.
  • Premium Symbols: Exotic animals like zebras, cats, and flamingos, each artistically rendered to stand out on the reels.
  • Super High-Pay Symbol: The majestic golden Hippo, the star of the show, offering the highest payouts.


With HippoPop, the potential for hefty payouts is immense, encapsulated in the game’s structure and features:

Symbol 3 of a Kind 4 of a Kind 5 of a Kind
Golden Hippo 1x 2x 4x
Flamingo 0.8x 1.6x 3.2x
Frog 0.4x 0.8x 1.6x


The game begins with 243 ways to win, but through the PopWins feature, this number can soar. In the base game, the grid can expand to offer up to 15,552 ways to win. This expansion continues into the free spins round, where the paylines can reach an astonishing 65,536 ways to win, making each spin a thrilling possibility for big wins.

Pros & Cons

Pros Cons
Innovative PopWins mechanic that increases engagement and potential wins. The pace of the game may be considered slow by some players.
Vibrant, colorful jungle theme inspired by Oaxacan arts and Alebrijes visions. Lacks traditional wilds and scatters, which may disappoint some traditionalists.
High maximum win potential of up to 48,150x the stake. Bonus round acquisition may be challenging due to the high volatility.

On the higher end, the maximum bet is set at $40 per spin, catering to players looking for higher stakes and bigger win potentials.

Game Jackpot

HippoPop boasts a game jackpot with a maximum win potential of up to 48,150 times the stake, making it an enticing choice for those chasing big payouts. The game operates on a highly volatile math model and offers a Return to Player (RTP) rate of 96.1%.
