Developer HippoPop™ by AvatarUX is a video slot built on the PopWins™ mechanic and released on 21 May 2021. The game uses a ways-to-win format on five reels, with super high variance and an RTP listed at 96% in one source and 94% in another. Its reported win potential reaches 20,000x.
In the demo version, players can play for free and practice before playing for real money. The base game is designed around expanding reels: every win triggers a pop that adds symbols, extending the grid and increasing the number of ways to win. Successful sequences can push the layout to 9 symbols high and create up to 524,288 ways.
Bonus features include free spins, which are unlocked by fully expanding the base game. During free spins, hippo symbols can increase in value as the reels grow, while a two-tier gamble wheel offers a chance to risk winnings for extra multipliers and additional reels before the bonus round begins.
