Drops of Insanity Slot Review

Drops of Insanity is a medium-volatility slot from Play’n GO, combining a bizarre laboratory setting with cascading reels, multiplier charges and a second grid positioned above the main playing area.

The game takes players into the laboratory of a mad scientist, where strange aquatic creatures and biotechnology experiments provide the inspiration for its unusual design.

Fish-like humanoids, scientific equipment and mysterious potions appear throughout the game, creating an atmosphere that mixes science fiction with dark humour.

Unlike conventional slots that introduce replacement symbols directly onto the reels, Drops of Insanity uses an additional 5×3 upper grid to supply new symbols whenever winning combinations disappear from the main playing area.

The game features 10 fixed paylines, a multiplier meter that increases through accumulated charges, and a Free Spins feature where multiplier progress carries over between spins.

With a reported default RTP of 96.20%, medium volatility and a maximum advertised payout of 6,000x the stake, Drops of Insanity offers an unusual variation on traditional cascading gameplay.

Game Features

Drops of Insanity uses two separate 5×3 grids, positioned one above the other. The lower grid is the main playing area, where winning combinations are evaluated across 10 fixed paylines.

Wins are formed by landing three or more matching symbols from the leftmost reel. The upper grid acts as a holding area for replacement symbols.

Whenever a winning combination forms, the winning symbols disappear from the lower grid, allowing new symbols to cascade down from the upper section. This arrangement lets players see which symbols are waiting above the main reels before they enter the playing area.

Only symbols in the lower grid contribute to regular winning combinations.

Wild Symbols

Wild symbols initially appear in the upper grid and can enter the main playing area through Cascades.

Once a Wild reaches the lower grid, it can substitute for regular paying symbols to help form winning combinations. Wilds also contribute to the game’s multiplier system.

Each Wild that reaches the main grid adds one charge to the multiplier meter.

Multiplier Meter

The Multiplier Meter is one of the central mechanics in Drops of Insanity. It accumulates charges from special symbols entering the main playing area.

Every three charges increase the active win multiplier by +1x. The increased multiplier applies to subsequent wins during the same game round.

Charges are awarded as follows:

Special SymbolMultiplier Charges
Wild+1 charge
Scatter+3 charges

A Scatter therefore contributes enough charges to increase the multiplier by one step.

During regular gameplay, the multiplier resets between separate spins, meaning any accumulated multiplier progress does not carry over into the next ordinary spin. This changes during Free Spins, where the multiplier and its charges persist between spins.

Spawn Symbols

Spawn symbols originate in the upper grid and can enter the main reels through Cascades. When a Spawn symbol reaches the lower playing area, it waits until the existing Cascades have finished.

It then removes itself and an average of seven randomly selected regular symbols from the grid. The resulting empty positions are refilled through another Cascade, potentially creating further winning combinations.

Scatter Symbols

Scatter symbols initially appear in the upper grid and must enter the main playing area through Cascades.

Each Scatter that reaches the lower grid contributes three charges to the multiplier meter.

Landing three Scatter symbols on the main reels during the same round activates the Free Spins feature. The triggering round’s multiplier and accumulated charges are retained when the bonus begins.

Free Spins

Landing 3 Scatter symbols in the main playing area triggers 10 Free Spins. The bonus retains the game’s cascading mechanics and multiplier system, but introduces one important change.

During Free Spins, the multiplier meter becomes persistent, allowing the active multiplier and accumulated charges to carry over between spins. This means that multiplier increases earned during earlier Free Spins remain available as the feature continues.

The triggering round’s multiplier and existing charges are also carried into the bonus.

Landing another 3 Scatter symbols during Free Spins retriggers the feature. The total number of Free Spins is capped at 120.

Creature Feature

During Free Spins, the Spawn mechanic is replaced by the Creature feature. This feature removes an average of nine regular symbols from the playing area and initiates another Cascade.

The Creature feature can activate randomly during the bonus. It is also guaranteed on every fourth Free Spin that has failed to increase the multiplier, as described in the supplied game information.

By removing regular symbols and creating another Cascade, the feature provides additional opportunities for new combinations and multiplier charges. However, the removal of symbols does not guarantee a winning combination.

RTP, Volatility and Maximum Win

Drops of Insanity has a reported default RTP of 96.20% and a medium volatility rating.

The maximum advertised payout is 6,000x the stake. The game does not include a Bonus Buy option, so Free Spins must be activated through the regular Scatter trigger.
