Our rating:
  • A playful and volatile slot from Elk Studios
  • Zappy feature is both fun and unique
  • A low RTP but little else to complain about

ELK Studios steps into chaotic territory with ZapLab, a cluster pays slot featuring the electric Zappy and his vendetta against the mad scientist Dr Mayhem. Played on a 7×7 grid, wins form by landing clusters of five or more matching symbols, triggering the Avalanche mechanic as winning symbols are removed and new ones tumble down. With an electrifying setting that feels like a blend between science fiction and quirky cartoon, ZapLab brings a vibrant and humorous touch to the grid slot formula. The RTP is set at 94% as usual, and there’s a highly volatile math model. The max win of 10,000x your bet promises a serious zap of excitement for those lucky enough to harness the lab’s full potential.

ZapLab Slot Bonuses and Features

Monster Meter. Every winning symbol fills the Monster Meter. Once full, it awards either a random Monster modifier or a Feature Symbol. Pending features activate sequentially when no more wins occur. The Monster Modifiers include:

  • Monster Reload: Awards a redrop with existing Zappy symbols remaining.
  • Wild Flip: Replaces all instances of a chosen symbol with wilds.
  • Monster Chunks: Replaces random symbols with 2×2 sized symbols.
  • Monstrous: Expands a symbol into a 3×3, 4×4, or 5×5 mega symbol.
  • Zapocalypse: Drops in Dr Mayhem symbols which are zapped by Zappy.

Feature Symbols. Feature Symbols can land randomly or be awarded by the Monster Meter:

  • Omniblast: Creates an X-shaped explosion replacing symbols with a random type.
  • Electroshift: Upgrades a random symbol type to a higher-paying one.
  • Twilight Twirl: Selects and transforms into a chosen symbol, clearing others.

Shockwaves. Filling the Monster Meter five times triggers Shockwaves, firing off all Monster Modifiers in a set sequence. If you manage to fill it again during Shockwaves, the process repeats.

Zappy. Zappy is a special wild who jumps to random positions after helping form a win, leaving regular wilds behind. When he zaps Dr Mayhem symbols, it increases his multiplier. Before final win evaluations, Zappy can expand to up to 4×4 size.

X-iter Bonus Buys. ELK’s X-iter feature allows players to directly access special modes, depending on your region:

  • Shockwaves Hunt: 3x bet with a higher chance of Shockwaves.
  • Zappy’s Turf: 5x bet guaranteeing a Zappy per drop.
  • Amplifier: 25x bet with only Monster Modifiers from the Monster Meter.
  • Shockwaves: 100x bet guaranteeing Shockwaves.
  • Maxed Monsters: 500x bet starting with a Monstrous 5×5 symbol and cycling only Chunk and Monstrous features until Shockwaves are triggered.

Conclusion

ZapLab slot from Elk Studios clearly draws inspiration from some other games but spices up the formula with its own chaotic flair and charismatic lead, Zappy. The Monster Meter system, combined with explosive modifiers, feature symbols, and the Shockwaves mechanic, offers players a lively and highly dynamic experience. While its inspiration might be obvious, ZapLab delivers enough originality in its pacing, character design, and rewarding potential to stand on its own. With a max win of 10,000x and exciting, layered gameplay, ZapLab is a strong entry for fans of cluster pays chaos. As usual though, the RTP is the biggest drawback at just 94%.
