About Reactoonz Slot Game

Reactoonz slot has a cartoon theme that revolves around bizarre googly-eyed aliens. This video slot has a 7×7 reel configuration with no definite number of paylines.

The Reactoonz slot has seven symbols per reel. These symbols consist of various aliens that look different from each other. By “different”, we mean that none of them seems to belong to a similar aliens species as the other. Each of them has a different face shape, colour, number of eyes, and hair from the other.

The reels are on a hologram 3D projector. Beside the reels is a giant alien that can also be seen on another hologram projector. This floating disk-like projector is smaller than the one projecting the reels.

Everything on the game screen looks futuristic and cutesy at the same time. Add to this the appropriately fun background music and sound effects. It is like you have just been transported to a parallel universe where your childhood monster aliens are your companion.

The game logo can be seen on the upper lefthand corner of the game screen, on top of a capsule-like structure with a transparent body. The game colour scheme consists of blue and silver. These graphics blend well together to have that kiddie feel the effect on the players.

Interactive Features

Reactoonz slot boasts interactive bonus features that would give you more chances of winning.

  • Cascading Reels feature

The Reactoonz slot has a Cascading Reels feature where the slot symbols drop down into the reels.

You can get a winning combination when five of the same symbol connects in either a horizontal or vertical cluster.

The winning symbols then get removed from the grid, and new symbols cascade down to fill their places.

This feature will continue until you no longer land a winning combination.

  • Quantum Leap features

When you land a win, the five Quantum Leap charge meters will increase one by one.

When a win charges a meter, the game will randomly add one of the quantum features to the queue.

The quantum features are as follows:

Implosion feature– This feature transforms three to six symbols into Wilds. This feature will also destroy adjacent symbols.

Alteration feature– This feature chooses one random low-value symbol.

This symbol has all instances of transforming into another symbol.

If there is no low-value symbol on the reels, the feature will choose a high-value alien instead.

Demotion feature– This feature destroys and removes all instances of low-value symbols appearing on the reels.

Incision feature– This feature cuts a Wild into the centre.

This cut creates two intersecting diagonal lines through the reels.

This feature will then display a randomly chosen symbol.

  • Gargantoon feature

Once all five meters are charged, the Gargantoon feature adds a Wild, taking up a 3×3 space on the grid.

For every cascade, the Gargantoon separates into two 2×2 Wilds.

The next cascade will again divide the Gargantoon into nine 1×1 Wilds.

If you cannot land a win during this feature, the Gargantoon will trigger a quantum feature randomly.

  • Instability feature

During this feature, the Gargantoon will randomly drop 4 to 8 Wild symbols onto the reels if you have a non-winning spin.

  • Giantoonz feature

The game triggers this feature when four matching symbols appear adjacent to each other in a square shape.

The Giantoonz will double your wins.

  • Fluctuation feature

On each spin, the Fluctuation feature marks a random low-value symbol as the fluctuating symbol.

If the symbol happens to be a part of a winning combination, it will leave 2 Wild symbols behind to take its place on the grid.

What Symbol Triggers the Reactoonz Slot Bonus Free Spins?

Reactoonz slot does not have a Free Spins feature.

Payline and Stakes

Reactoonz slot symbols include four low-paying aliens, four high-paying aliens, and a Vortex Wild symbol.

The pink alien is the highest value symbol; it can give you 750 times your stake if you land five across a payline.

The most you can win from Reactoonz spins or cascade is 4,570 times your total stake.
