Slot Details

Reactoonz is a cascading grid slot with seven columns and seven rows. Wins are paid for clusters of five or more matching symbols in any direction. The game can be played for as little as 0.20 credits per spin up to 100 credits. The RTP of this high variance game is set at 96.51%. Use Autoplay to set up 5 to 100 consecutive spins without interruption.

Open the game to find a colourful design with a mystical vortex orb and a winnings display on the left as well as the five tubes of the Quantum Leap meter and the three-eyed Gargantoon himself on the right of the slot window. The meter will play a vital role in triggering the features on Reactoonz. Gargantoon is napping whenever he can, but poke him enough times to see him award random features and ultimately jump on to the grid as a giant 3×3 wild. A futuristic soundtrack and Gargantoon’s snoring provide the main audio.

All pay symbols are aliens, appearing in a variety of shapes and colours. The most obvious difference is, however, the number of eyes. At the low end, they are one-eyed aliens in yellow, dark green, brown and purple colours, followed by two-eyed aliens in blue, orange, light green and pink colours on the high level. Pays for clusters of five range from 0.1x to 1x your bet. The maximum win per symbol is awarded for clusters of 15 or more symbols, ranging from 3x to 750x your stake. Wild symbols are the vortex orbs and Gargantoon himself, substituting for all symbols. There are no scatter or bonus symbols on this slot.

Cascading Symbols Mechanic Explained

Reactoonz does not have spinning reels with symbols as a normal video slot, instead, symbols cascade from the top onto a 7×7 game grid. Any clusters of minimum five symbols or in combination with wilds will explode and new symbols will drop into place. This continues as long as new winning combinations hit after a fresh drop. All wins are accumulated and paid at the end of the spin sequence.

Giantoonz and Fluctuating Symbols

Yeah, we thought the same. What on earth can that be? The two types of symbols can appear on any cascade to award extras that will help you score bigger wins and trigger the Quantum Leaps.

  • Giantoonz – any four symbols landing adjacent in a square will unite to form a single Giantoonz symbol. Any wins are doubled if it will be part of a winning combination.
  • Fluctuating Symbols – One random one-eyed symbol will be marked with a glow in every new game round. If they form a winning combination, they will leave two wild symbols in their wake after they explode.

Gargantoon’s Random Instability

The random feature can trigger on every none-winning spin after the initial cascade. Gargantoon will transform four to eight symbols in view into wilds, making it easier to score a winning combination.

Gargantoon Quantum Leap Feature

The Quantum Leap Meter with five tubes is displayed on the right of the game grid and is filled up by scoring winning combinations. The number of symbols in every winning combo is transferred to the meter. To complete one tube, it will need 25 symbols after which Gargantoon will award a randomly chosen feature. Filling the fifth tube will launch Gargantoon himself.

  • Incision – Forms a diagonal cross from corner to corner across the play grid in both directions, turning all symbols in its path into a common symbol or a wild symbol.
  • Implosion – Transforms three to six symbols into wilds and lets all adjacent symbols explode
  • Demolition – Destroys every low-value symbols in view and cascading new symbols into place
  • Alteration – Randomly selects one low-value symbol and turns all in view into a new common symbol.

Gargantoon – The Grand Finale

This is the one, the moment, the climax, the grand finale of your adventure on Reactoonz. Filling up the fifth tube on the Quantum Leap Meter will trigger the Gargantoon feature which will see Gargantoon himself jump onto the game grid as a 3×3-sized mega wild. After all wins are paid, the second cascade will drop in and Gargantoon now appears twice as a 2×2-sized super sized wild. Finally, on the third cascade, he will turn into nine 1×1 single wilds.

Final Verdict

Aren’t they adorable little critters these cute aliens? Not just that in our opinion, but they are also part of a fast-paced and volatile game with entertaining features and engaging gameplay. Your aim will be to reach Gargantoon and then to hit 15 or more “pinks” and possibly four of them in a square to activate the x2 multiplier as that alone will pay a mega win of 1,500x your bet.
