ZapLab

ZapLab operates on a 7-reel, 7-row grid utilizing cluster pays, where wins are formed by landing five or more matching symbols adjacent horizontally or vertically. The game's RTP stands at 94%, and it boasts a hit frequency of 26.1%, indicating frequent, albeit varied, win occurrences. Players can place bets ranging from €0.20 to €100 per spin.

Visually, the game immerses players in a cartoonish laboratory filled with bubbling beakers, strange contraptions, and animated monster symbols. The soundtrack complements the theme with quirky tunes and electrifying sound effects, enhancing the overall gaming experience.

Cascading reels

Winning clusters are removed from the grid, allowing new symbols to cascade down, potentially creating additional wins within the same spin.

Monster meter

• Monster Reload: Awards a symbol redrop after the current cascade ends.

• Wild Flip: Transforms all instances of a randomly selected symbol into wilds.

• Monster Chunks: Replaces random symbols with 2×2 blocks.

• Monstrous: Expands a random symbol into a 3×3, 4×4, or 5×5 block.
