ZapLab Slot Overview
Those who haven’t had the chance to read the associated game docs might not have heard of the “mad Dr. Mayhem,” who conducted controversial experiments in the 20th century. His goal? To harness the souls of the past using electricity. One unexpected result of these experiments is Zappy, an electric being who holds a personal vendetta against Dr. Mayhem. The arena for this showdown is ZapLab, a cluster-pays online slot from Light & Wonder, owned by the studio ELK Studios.
The Setting: A Lab Full of Oddities
Dr. Mayhem’s lab might be filled with strange experiments, but the place itself looks surprisingly normal—aside from the brain in a vat bubbling by the window. It seems like a respectable scientific space, though a faint green glow from the floor hints at something ominous beneath the surface. Littering the game grid in the middle of the room are a series of strange Reactoonz-type entities, adding a playful element to the eerie setting. As expected okebet from ELK Studios, the slot’s audio perfectly complements the visuals, enhancing the immersive atmosphere.
Gameplay Mechanics: Cluster Pays and Avalanches
ZapLab is a 7×7 matrix cluster-pays slot where winning clusters are created when five or more matching symbols connect vertically or horizontally. Winning symbols are collected and removed from the grid, but Zappy and feature symbols stay in place. All other symbols will drop vertically, while new ones come in from above to fill the empty spaces. This avalanche mechanic continues until no new clusters appear. If you’re playing with okebet, you’ll enjoy the action as new symbols drop into place, keeping the tension high with every spin.
Symbols: The Monsters and Bottles
The lower-paying symbols in ZapLab are four eyeballed liquid bottles, while the higher-paying symbols are the four-eyed monsters. Winning a five-of-a-kind cluster will award 0.1x to 0.5x the bet, while 25+ symbols in a cluster can reward up to 1,000x. The game also includes a unique feature where four identical pay or wild symbols can form a 2×2 symbol, and the spaces below these symbols will fill with 1×1 symbols of the same type.

Wilds and Feature Symbols: Unlocking Big Wins
Wilds in ZapLab substitute for any regular pay symbol, and they can be incredibly useful in forming winning clusters. Wild-only wins have the same value as the highest-paying symbol, making them highly valuable. But the real fun begins when the Monster Meter starts filling up. This feature tracks the number of winning pay symbols collected, and once it’s full, it rewards a random modifier or feature symbol, significantly increasing the potential for big payouts. Keep an eye out for Zappy, who can add excitement by jumping around the grid and transforming the game.
Monster Meter: Unlocking Special Modifiers
The Monster Meter is crucial for unlocking the game’s modifiers and feature symbols. Each time the Monster Meter is filled, it awards a random modifier or feature symbol, creating more ways to win. The modifiers include things like Monster Reload, which awards a symbol redrop, and Wild Flip, which replaces a random symbol with wilds. Some modifiers are even more powerful, such as Monstrous, where a symbol expands to a massive 5×5 size, or Zapocalypse, where Dr. Mayhem symbols are zapped off the grid by Zappy, adding extra excitement.
Shockwaves: A Chain Reaction of Wins
When the Monster Meter is completely filled five times in a row, it activates the Shockwaves feature, unleashing a chain reaction of modifiers. The Shockwaves cycle begins with Monster Reload, followed by Wild Flip, Monster Chunks, Monstrous, and finally Zapocalypse. If the Monster Meter fills up again during this feature, the cycle will repeat, offering a potentially explosive series of wins. If you’re playing with okebet , you may find that this feature is the key to triggering huge payouts.
Zappy: The Wild Card of the Game
Zappy is a wild symbol that can land on any symbol drop and substitutes for all paying symbols. When part of a winning cluster, Zappy jumps to a new random position, leaving behind a wild symbol. Zappy also attacks Dr. Mayhem symbols in view, zapping them off the grid and increasing his multiplier. Zappy’s true potential shines when he expands to larger sizes, such as 2×2, 3×3, or even 4×4, just before the win evaluation. This makes him a highly valuable symbol for players seeking big rewards.
X-iter: Buying Into Bonus Modes
The X-iter feature is where things get really interesting. It allows players to flip between bonus modes, each with unique rewards. For example, Shockwaves Hunt offers a better chance of triggering the Shockwaves feature, but it costs three times the normal bet. Zappy’s Turf guarantees Zappy for every drop, but at a cost of five times the bet. There’s also the Amplifier mode, where a pending feature from the Monster Meter will be triggered, but it comes with a hefty 25x the bet price. If you’re feeling adventurous, you can buy the Maxed Monsters drop for 500x the bet, guaranteeing a Monstrous 5×5 and activating the Monster Meter for even more intense gameplay.
Conclusion: A Thrilling Adventure
ZapLab offers an exciting and unique experience, blending science fiction and wild features into a highly volatile slot. While its gameplay might remind some of Reactoonz from Play’n GO, it adds its own flair with the Monster Meter, Zappy, and Shockwaves features. If you’re looking for a slot with plenty of twists and turns, ZapLab could be just what you need. Whether you’re playing casually or taking advantage of the okebet feature for higher stakes, the potential for huge rewards is always on the horizon.
