PopRocks

PopRocks is a video slot from AvatarUX that runs on a 5-reel grid which starts at 3 rows and can expand up to 7 rows high. The game uses the PopWins™ mechanic: whenever a winning combination is formed, the symbols that contributed pop off the reels and are replaced by two new symbols each, which increases the reel height and the number of ways to win. At its base size the game offers 486 ways to win; when fully expanded (5×7), that climbs to 33,614 ways.

Every time seven symbols have been popped during a single winning sequence, a win multiplier increases by +1x. If the grid reaches the full height of seven rows on every reel in the same spin, Bonus Mode is triggered—in this mode one wild symbol appears at a random position, the multiplier now increases by +2x for every seven popped symbols, and popped symbols are replaced by just one new symbol to maintain the maximum grid size.

There is no traditional free spins round, no Scatter symbols, and no bonus buy option in PopRocks. The extra action all comes from the base game and its escalating chain reactions via PopWins plus the Bonus Mode tweaks. Symbols pay both ways from the left and right on adjacent reels, which helps triggers early even before expansion takes full effect. Wilds are unlocked only after reaching the maximum grid height and help sustain further wins. The theme blends glowing gems, premium creature-wrapped stones, and magical fantasy visuals with vibrant, arcade-style aesthetics.

You can try it for free in demo mode or play it for real money.
