ZapLab Online Slot

ZapLab Online Slot Review

Cute monsters in various shades, styles, and sizes, plus the mad scientist who created them, appear in the ZapLab online slot from ELK Studios. It’s a cluster pays game where you win as matched symbols connect together on the 7x7 grid and each win triggers cascades of the remaining symbols.

Cascades can repeat over and over as new symbols replace those in win, with all winning symbols filling a Monster Meter to unleash special features. These can include another cascade, extra wilds that can act as others, or giant symbols which count as up to 25x individual ones. Fill the meter enough times to get all features at once! A wild ball of energy can zap the scientist, leaving giant wilds with multipliers behind, and modifier symbols transform, upgrade, or remove other types.

The electrifying gameplay and features are available in desktop and mobile versions of the ZapLab slot machine. It’s a highly volatile game with the usual relatively low return to players of 94.00% that most ELK Studios slots offer. Spin the reels of this cartoonish game at our top online casinos and wins can hit a huge 10,000x the stake.

How to Play the ZapLab Slot

The mad Dr. Mayhem, in his attempts to harness souls, has accidentally released Zappy, a manic ball of grinning electricity, and a range of colourful monsters. That’s the backstory to the ZapLab slot game, where the Dr., Zappy, and a rich selection of monsters in bright colours, with different expressions, and powers land across 7 columns and 7 rows. Think of Monsters Inc. style and you’ll get the idea.

They sit against the backdrop of a vintage lab with an adjacent monster meter waiting to fill with winning symbols to unleash the mayhem. A whimsical soundtrack sounds suitably weird as you play the ZapLab slot machine on Android, iOS, or Windows mobiles, as well as on desktop platforms.

It’s easy to use the standard ELK Studios controls, with the coins button revealing 12 bet options from 0.20 to 100.00. Several X-iter bonus buy options unlock modifiers with upfront stakes although like the Auto and Turbo features, these are not available to UK-based players.

ZapLab has lots of unusual features, so a read through the paytable is recommended. It’s reach via the 3 lines on the panel and also has details on what symbols pay when at least 5 of the same type land on the grid connected horizontally or vertically. Depending on the size of the cluster, the least valuable blue monster in a jar pays from 0.1x to 20x, and the highest value red creature is worth from 0.5x to 1,000x your bet.

Modifiers & Other Features of the ZapLab Slot Machine

A yellow wild symbol helps to complete clusters, improve their values, or connect clusters as it has the power to step in for others when possible. 

All winning symbols explode and vanish, leaving spaces for those above to drop down as new symbols appear from the top. This cascading symbols feature repeats if the new mix includes winning clusters and there’s no set limit to how many times it can happen in a sequence.

All winning symbols zap across to the monster meter, and once full, it unleashes modifiers at the end of the series. You can fill the meter several times over, which combines these modifiers, or filling it 5 times over a series of cascades unlocks Shockwaves, with all 5 features awarded. Here’s what you get at the end of cascades –

• Monster Reload. This awards another cascade, or ‘Redrop’.
• Wild Flip. Picks a random symbol and replaces all examples in view with wilds.
• Monster Chunks. Chooses a random number of symbols and replaces them with 2x2 examples, which count as 4 individual symbols. 
• Monstrous. Expands a random symbol to 3x3, 4x4, or 5x5 which count as 9, 16, or 25 symbols for a guaranteed win. 
• Zapocalypse. A random number of Dr. Mayhem symbols appear. Zappy then attacks the Dr. replacing him with wild Zappies, each of which has a multiplier. Zappy can also appear in 2x2, 3x3, or 4x4 sizes. 

Monster meters reset at the end of cascades or once they have awarded their features. 

Randomly, special W symbols award further in-game modifiers –

• Omniblast. This explodes, replacing all symbols in diagonals along with itself, into another randomly chosen type.
• Electroshift. Picks a random symbol type then upgrades it, along with itself, into a more valuable symbol. 
• Twilight Twirl. This modifier sees all examples of a random symbol remain in place as all others explode. The Twilight Twirl symbol also transforms in to the selected type.

There are no free spins, respin, or other standalone bonus rounds here. Everything happens in the main games and at the end of any series of cascades.

ZapLab Slot Maximum Wins, Volatility, & Average Returns

Wins from any paid spin can hit 10,000x your bet, or 1,000,000.00 at the maximum stake of 100.00. You’ll need a long enough run of cascades with enough modifiers to reach this target. 

It’s a high volatility slot where relatively generous prizes can combine with comparatively few winning spins. Of course, that’s a long-term trend, as is the slightly disappointing return to players of 94.00%. High volatility games usually have returns of 96.00% or more.

Our ZapLab Slot Rating

This fun game packs a lot of monster-themed action onto the grid, where everything happens in the base games. Cascades can run and run, and once they end, features from any filled monster meters can restart the sequence as they remove symbols, place extra wilds on the screen, unlock giant symbols or zap Dr. Mayhem for wilds with multipliers. In-game modifiers help in their own ways as they replace, transform, remove, or upgrade symbols.
