Lab of Madness Game Demo: Review

Lab of Madness: It's a Wild! is the new crazy laboratory-themed creation from Play'n GO: a 5×4 slot with 20 fixed paylines, pulp spirit and a special WILD system that changes appearance based on what we load at the top of the reels. Vibrant, original and colorful, this online slot machine will surely win over anyone looking for something new in the world of reel betting!

Theme and Graphics of Free Lab of Madness

The setting is a gothic-comic laboratory: operating tables, Tesla machines and flashing bulbs frame a dirty-white board, scratched with comic-style vignettes. The palette alternates between monochrome "mortuary" elements (anatomical hearts, saws, gloved hands) with acid flashes of ORBS (red, green, purple) and the monster-protagonist's face that serves as Wild. 

Interface and readability are the priority: clean symbols, clear lines, minimal UI for mobile and desktop. The audio plays with distorted guitars and electric discharges, emphasizing plot twists during expansions and respins. It's a coherent aesthetic: intentionally "dirty" but sharp, with a visual rhythm that well accompanies the high volatility.

Symbols and Payouts

The slot pays on 20 lines from left to right, one win per line (different lines are added together). With total bet 1€ as reference, the paytable shown in-game indicates clear values:

• Wild (pays and substitutes) - up to 10×
• Scientist - up to 10×
• Anatomical Heart - up to 5×
• Gloved Hand and Saw - up to 4×
• A, K, Q, J, 10 - up to 2×

The ORBS (red, green, purple) don't pay directly: they're function symbols that charge corresponding BULBS. The Power Up doesn't pay by itself and serves to trigger the Zap Prizes routine.

Bonus Features of Lab of Madness Slot

The game's strength lies in its modular system: charge bulbs, select the Wild's "imprint" and then play Free Spins built on that choice (or combination of choices). Here's everything in detail.

Bulbs & Orbs

Above the grid runs a row of three light bulbs — the Bulbs — each linked to a different type of Special Wild: red calls Multiplier Wilds ("X" icon), green unlocks Expanding Wilds (expanding figure), purple activates Walking Wilds (movement arrow). In the base game, each Orb that lands on screen transfers energy to the same-colored Bulb: the bulb changes intensity, sparkles and shows at a glance how far from peak it is. 

If during the same spin the flow reaches Overcharged level, that Bulb triggers Free Spins and "signs" their nature with its special Wild. It's possible for two or even three Bulbs to saturate simultaneously: in that case the bonus will start with combined effects, creating one of seven total variants (the three singles and four possible combinations). 

Orbs can appear during free spins too, but the bonus activation condition is determined in the base game: Bulbs charge is a visual indicator tied to the spin where you get it and resets when Free Spins start.

Free Spins

When a Bulb reaches Overcharged, the slot awards 10 Free Spins and transforms the Wild. If it's Multiplier Wild, each line including that joker is multiplied by x2, x3, x4 or x5; if multiple Multipliers participate in the same line, values multiply together (example: x2 and x3 become x6). 

With Expanding Wild the joker that lands extends to cover the entire reel; if the Multiplier modifier is also active, the entire expanded reel carries the same multiplier. The Walking Wild profile instead stages a small march: each Wild in view triggers a free re-spin and moves one reel left each step until leaving the screen. 

Combinations are the spectacular heart of the feature: a Walking + Expanding generates entire Wild reels that slowly advance leftward maintaining extension, while adding the Multiplier allows that "walking" reel to replicate its value at each re-spin, creating payment trajectories that can interweave across multiple lines. 

Power Up & Zap Prizes (base game only)

The Power Up symbol can appear only in the base game (maximum one per spin). When activated, you have the chance to win one of four Zap Prizes shown on the side:

• Mini
• Minor
• Major
• Mega

The panels in game show preset values. These are fixed prizes linked to your bet/currency according to the casino version. It's a parallel path to the main bonus: it doesn't replace Free Spins, but introduces quick peaks during the session.

Bets, RTP and Volatility

The betting range is wide and allows building sessions with different approaches: starting from 0.20 per spin up to 100. Each stake variation proportionally resizes both paytable payments and values shown in Zap Prize panels.

Play'n GO publishes multiple RTP configurations and the operator chooses which to adopt: the highest profile reaches 96.2%. The active value in the AAMS casino is always viewable in the information screen and is a concrete variable for long-term performance: with equal playing style, a lower RTP tends to erode the budget sooner. 

The volatility is high (7/10) and it shows: base spins can flow lightly, with micro-centers of value entrusted to linear connections or a sudden Zap Prize; but when the Bulbs bar leads to Free Spins with Walking, Expanding and Multiplier, the session curve changes tone and can produce important twists. It's a title that performs best with unhurried sessions, bets proportionate to bankroll and disciplined profit management after a particularly rich bonus (especially if you've triggered two or three modifiers simultaneously).

Jackpot and Maximum Wins

Lab of Madness doesn't have a progressive jackpot. Instead, it integrates Zap Prizes (Mini/Minor/Major/Mega) activatable with Power Up in base game. The Mega prize shown at 5,000 represents a high-profile straight objective and, together with Free Spins synergies, supports the declared maximum win of 8,000× the bet. It's a competitive cap for a 5×4 fixed-line slot and consistent with Play'n GO's DNA on medium-high/high volatility.

Similar Slots

Those who enjoyed this game might try:

• Reactoonz (Play'n GO) – Non-linear and grid-based, but with energy to charge and peak moments generated by special symbols: perfect if you like the idea of "accumulating power" and releasing it in grand style.
• House of Doom 2: The Crypt (Play'n GO) – Dark aesthetic and evolving Wilds that change game rhythm; darker, but similar in "metal/horror" taste.
• Raging Rex 2 (Play'n GO) – Offers Walking Wild in feature and multiple Free Spins choices reminiscent of the modular approach; different theme, similar dynamics in Walking Wild impact.

Game Mechanics

The set is a 5×4 with 20 fixed lines paying left to right on adjacent reels, with one win per line and sum of wins on different lines. The mechanical plot arises from interaction between ORBS and BULBS. 

In Free Spins the WILD becomes the absolute protagonist: 

• if it's Multiplier, each line including it gets multiplied and, if two or more multiplier Wilds participate in the same line, values multiply together;
• if it's Expanding, the symbol extends to fill the reel where it lands and, if the Multiplier modifier is also active, that multiplier applies to the entire expanded reel;
• with Walking, each Wild generates a respin and advances one column left until leaving the grid.

Parallel to the main circuit runs a temporary but incisive mechanic: in base game the Power Up symbol can land. When it appears, the Zap Prizes screen activates instantly awarding one of four fixed side prizes (Mini, Minor, Major, Mega). 

Author's Notes

I appreciate when a "meta-feature" idea is clear even before being remunerative. Here the bulbs metagame works: I understand what I'm looking for (Multiplier? Expansion? Walking?) and can imagine the peak when combining them. Walking + Expanding with multiplier is the true signature: respins generate a satisfying visual progression and, if lines hold, counts rise quickly. 

The other entertainment channel is Power Up: not a cosmetic diversion, but a shortcut to fixed prizes that breaks voids. The flip side is volatility: the game doesn't forgive brief sessions or impatient approaches. In a very large Play'n GO library, Lab of Madness carves its place thanks to the intelligent simplicity of its system and a recognizable aesthetic that, though caricatured, remains readable.
