Reactoonz 100: Slot Overview

Reactoonz 100 joins Play’n GO’s expanding line-up of 100 slots. In broad terms, these titles revisit well-known games and enhance them with added or upgraded mechanics, as seen in Sweet Alchemy 100, Moon Princess 100 and Rise of Olympus 100. For Reactoonz 100, the standout upgrade is a climbing win multiplier, which makes gathering winning symbols even more nail-biting. Most other elements remain familiar, so players can still expect cascading wins, queued features, and the Gargantoon finale.

Beyond the gameplay tweaks, Reactoonz 100 also receives a visual refresh. The backdrop especially leans far more into a spacey, galactic vibe. Items drift on both sides of the 7×7 grid; a sleepy Garga is still present, along with the new multiplier trail on the left, pulling in winning clusters and spinning as the value increases. Even with these updates, Reactoonz 100 keeps the same charm, thanks to the adorable one- and two-eyed Toonz filling the grid.

Rated 10 out of 10, Reactoonz 100 is a highly volatile slot and carries the familiar maximum RTP of 96.2%. Bets range from 10c to $/€100 per spin, and wins form when 5 or more matching symbols connect horizontally or vertically. Winning symbols are removed, leaving gaps that are filled as new symbols drop in, potentially creating additional wins.

Four one-eyed Toonz make up the low-paying symbols, while four two-eyed Toons represent the higher pays. Clusters of 5 OAK return 0.1x to 1x the bet, rising to 1.5x to 100x for 15+ OAK. Wilds substitute for all symbols. They can never be selected as Energized symbols, and wilds are not influenced by Quantum features.

Reactoonz 100: Slot Features

The Reactoonz 100 features list includes Energized Toons, the Quantum Charger, Quantum features, the Gargantoon, Instability, and Fluctuation.

Energized Toon

Any cluster that includes an Energized Toon is multiplied by the current multiplier. The Energized Toon’s position is first chosen at random once the multiplier reaches x2, and then a new position is selected after each cascade. Wins with one-eyed symbols raise the multiplier by +1, while wins with two-eyed symbols increase it by +3.

Quantum Charger

Winning symbols charge the Quantum Charger meter, and a feature is added to the queue after a win involving 25 symbols. As many as four random features may be queued, while the fifth queued feature is always the Gargantoon. Queued Quantum features activate when there are no more wins:

• Implosion – transforms 3 to 6 symbols into wild symbols while destroying all adjacent symbols.
• Incision – puts a wild symbol in the centre of the grid and creates two intersecting diagonal lines of the same random symbol.
• Demolition – destroys all one-eyed symbols and all matching symbols.
• Alteration – chooses one random one-eyed symbol, and all matching symbols turn into another symbol. Other symbols will be chosen if no one-eyed symbol is in view.

Gargantoon

The Gargantoon is always the fifth Quantum feature. When it triggers, the Gargantoon lands on the grid as 8 wild symbols in random positions. Once no further cascades can occur, it turns into two 2×2 wilds. When cascades finish, it becomes a 3×3 wild. The Gargantoon can never be an Energized Toon.

Instability & Fluctuation

On every non-winning initial spin, there is a chance that 4 to 8 wilds will appear on the grid. In addition, one one-eyed symbol type is randomly selected each round as the fluctuating symbol. If the highlighted symbols are part of a winning cluster, that cluster creates two wilds.

Reactoonz 100: Slot Verdict

Most 100 slots stay mechanically close to their originals, typically introducing one or two adjustments that significantly shift the win potential. Reactoonz 100 fits that pattern and also serves as a solid reminder of just how entertaining the original game remains. Play’n GO hit the mark with Reactoonz years ago, delivering one of the best cluster pays slots in online gambling, and the studio has revisited the Toonz cast multiple times since with releases like Gargantoonz, Gigantoonz, and Dr Toonz. None of those, including Reactoonz 2, have truly surpassed the original, and Reactoonz 100 may not either, but it’s a respectable rework—and it’s easy to see why some players might even prefer this version.

To begin with, the addictive rhythm of back-to-back clusters, the collection of winning symbols, and the build-up of helpful queued features is still very much intact. The difference now is that Reactoonz 100 adds a rising win multiplier to cluster payouts—though not to every cluster, only those that include Energized Toons. As a trade-off, several cluster values have been reduced quite a bit; for instance, the top symbol’s 15+ hit has fallen from 750x to 100x. Even so, the overall win potential remains unchanged, and can now, in theory, reach 10,000x the bet—the second-highest in the Toonz series, topped only by the unusual Dr Toonz. As always, that’s the stated potential on paper, and the real-world experience can be very different with PnG slots.

Other notable tweaks include the removal of the Giantoonz feature—perhaps it conflicted with the win multiplier—and the reversed way the Gargantoon combines, shifting from smaller wilds into bigger ones. Aside from that, the action plays very similarly to the original, which is a good thing, and the new mechanical and visual touches make Reactoonz 100 well worth checking out for Toonz fans.
