Hippo Pop Slot Review: A PopWins Adventure in the Watering Hole


Game Overview and Theme


Hippo Pop transports you to a sun-drenched African landscape, where a cheerful hippopotamus is the star of the show. The visuals are bright, cartoonish, and full of charm, with a relaxing soundtrack that complements the serene setting. Don't let the peaceful vibe fool you, though—the gameplay is anything but calm. The core of the experience is built around AvatarUX's signature PopWins feature, which can extend the reels up to 9 symbols high, unlocking up to 524,288 ways to win. It's a perfect blend of cute aesthetics and seriously engaging, high-stakes mechanics.

How to Play Hippo Pop: Rules and Betting


The game begins with a 5-reel, 3-row grid offering 243 ways to win. You can adjust your total bet using the coin value and bet level options, with a betting range suitable for all players—from a minimum of $0.20 per spin up to a maximum of $40. Wins are formed by landing matching symbols on adjacent reels from the leftmost reel onwards. The key to Hippo Pop's excitement is the PopWins mechanic: every winning combination causes the contributing symbols to "pop" and disappear, making room for two new symbols to drop into each vacated position. This can increase the number of rows and, consequently, the ways to win.

Symbols and Payouts


The symbols in Hippo Pop are split into low-paying and high-paying categories. The low-paying symbols are the classic 10, J, Q, K, and A, styled with a playful African twist. The high-paying symbols are the thematic animals: a colorful bird, a zebra, a crocodile, and the cheerful hippo, which is the most valuable regular symbol. The hippo also acts as a wild symbol, substituting for all other symbols except the scatter. Landing a full screen of hippo wilds on the max 7x7 grid is the key to the game's biggest potential payouts from the base game.

The Core Feature: PopWins Mechanic


The PopWins feature is the engine that drives Hippo Pop. After any win, the winning symbols are removed. Each empty space is then filled by two new symbols, effectively increasing the height of that reel by one row. This process continues as long as new winning combinations are created. With each cascade, the grid can grow, and the number of ways to win multiplies. The reels can expand up to 9 symbols high. This cascading, grid-expanding action is incredibly satisfying and can lead to extended winning sequences from a single spin.

Free Spins Bonus Round


Fully unlocking the base game grid triggers the Free Spins round, with a two-tier Gamble Wheel offering extra multipliers and reels before the spins begin. The bonus round starts with an expanded grid, and the PopWins mechanic is in full effect with a crucial twist: the grid does not reset between spins. Once you expand the reels during the free spins, they remain at their increased height for the remainder of the bonus game. This creates a snowball effect where you can build towards the fully expanded grid and up to 524,288 ways to win. Landing additional scatters during free spins awards extra spins, providing more opportunities to build and capitalize on the expanded grid.

Volatility, RTP, and Max Win Potential


Hippo Pop is classified as a high volatility slot. This means wins may not land frequently, but when they do, they have the potential to be significant. The game's RTP (Return to Player) is a solid 96.1%, which is around the industry average. The maximum win potential is the aspect that attracts many players. The official maximum win potential is 20,000x your stake. It's a slot designed for players who enjoy the thrill of the chase and the prospect of a substantial payout.

How Hippo Pop Compares to Other PopWins Slots


AvatarUX has built a strong reputation with its PopWins series. If you enjoy Hippo Pop, you'll likely want to explore other titles with similar mechanics. WitchyPoppins offers a magical twist on the formula, while Kitty POPpins brings feline charm to the expanding reels. For a more mystical theme, ArcanaPop combines the PopWins feature with tarot card symbolism. Each game offers a unique theme and slight variations in bonus features, providing plenty of variety for fans of the mechanic. You can explore all these and more in our dedicated high volatility games collection.

Pay attention to how the free spins round is triggered and how the persistent grid functions.
