PopRocks: AvatarUX's Expanding-Grid Fire Kingdom

PopRocks is a high-volatility video slot from AvatarUX, built around the studio's trademarked PopWins mechanic. The game starts on a 5-reel, 3-row grid offering 486 ways to win in both directions, and expands as play progresses, with the potential to scale up to as many as 33,614 ways to win at its largest configuration.

Theme and Gameplay Feel

Set in a moody fire-tribe kingdom, PopRocks pairs a fantasy warrior aesthetic with a slightly transparent reel design that reveals a shadowy castle in the background. A dramatic, high-energy soundtrack runs throughout, giving the game a cinematic atmosphere that will either draw players in or feel a touch much, depending on taste. Visually, it's a competent if fairly familiar take on the genre, built more around its mechanics than standout artwork.

How the Grid Expands

PopRocks pays both ways, so matching symbols landing across adjacent reels from either the left or right edge of the board form winning combinations. The expandable grid is the game's central hook — as the reels grow beyond their starting 5x3 size, the number of active ways to win climbs sharply, up to the maximum of 33,614. Popping symbols and the wider PopWins structure work together to reward longer sequences as the grid stretches to its full size.

What the RTP Means for Players

PopRocks carries a confirmed RTP of 96.8%, a genuinely generous figure that sits well above the typical industry range. That's a real point in the game's favour, particularly for a high-volatility title, since a stronger RTP helps offset some of the risk that comes with the swingier variance profile.

Volatility and Hit Frequency

This is a highly volatile slot, with a hit frequency of around 22%, meaning roughly one in every four to five spins produces some kind of win. Expect stretches of low-value or dead spins interspersed between the moments where the grid expands and the bigger multipliers kick in — patience is part of the deal with this style of PopWins game.
