How to Win in Reactoonz Slot

Playing the Reactoonz slot machine is a breeze, and you can easily grasp the game mechanics, even as a novice. The game is played on a 7×7 grid, deviating from the traditional slot machine layout. This grid structure introduces a more dynamic playfield into standard slot gaming.

Instead of paylines, Reactoonz features a Cluster pays system. You can land a winning combination by spinning at least five matching symbols adjacent to each other, vertically or horizontally.

The best part is the slot game incorporates cascading reels. So, when you land a win, symbols forming the win disappear, and new ones drop in to fill the grid. The cascading feature continues to apply until no additional winning cluster is created.

The Best Bonus Features of Reactoonz Slot Machine

While you won't find Reactoonz free spins, the game provides other exciting bonus features to keep the gameplay dynamic and rewarding. The heart of all the reel action in Reactoonz revolves around the cascading feature.

Every win in a game round incrementally contributes to charging the Quantum Leap meters. Once a meter reaches full charge, a random quantum feature is added to the queue, creating multiple wins. The bonus quantum features trigger at the end of your spin.

This section digs into the five possible bonuses in the Reactoonz slot; each bagged on consecutive wins within a spin.


This Reactoonz bonus feature eliminates all one-eyed symbols from the grid, leaving empty spaces for new cascading symbols. The feature forms new symbol clusters that can trigger potential multiple wins within the spin.


The alteration feature selects one random one-eyed symbol on the grid, and all other matching symbols transform into another. This transformation can create larger clusters of higher-paying symbols, landing more lucrative wins.


This feature turns 3-6 random symbols on the grid into Wilds while destroying all adjacent icons. The wilds can replace other symbols on the grid to create winning combinations.

The feature introduces a wild symbol at the center of the grid, paving the way for a dynamic transformation. This activation prompts two diagonal lines of matching symbols that intersect the grid. It boosts the potential of landing winning clusters, adding an exciting dimension to the Reactoonz gameplay.

This Reactoonz bonus game concludes when you have activated all queued Quantum features, and no further winning combinations appear on the screen.


The ultimate bonus feature in Reactoonz is the Giantoonz, which activates when you land four regular symbols adjacent to each other in a square.

Any winning combinations that include the Giantoonz are doubled. Also, each spin marks a random one-eyed symbol as a fluctuating symbol. If the fluctuating symbol is part of a winning cluster, it's replaced by two wild symbols.

Reactoonz Symbols & Payouts

The whimsical reels of Reactoonz feature a lively range of colorful space-inspired symbols. From quirky aliens to special wilds, each symbol in the slot machine adds an invective twist to your gaming experience. 

One-eyed symbols make up the low-paying category in the Reactoonz slot game. This category includes four symbols varying in colors: yellow, green, red, and purple.

These one-eyed symbols pay as low as 0.16x your stake for landing a winning cluster of five matching symbols. On the higher side, you can bag a maximum of 16x your bet for landing at least 15 purple/red matching one-eyed symbols adjacent to each other in a spin.

Conversely, two-eyed aliens constitute the higher-paying standard symbols in the slot machine. This symbol category comprises four colored aliens: blue, orange, green, and pink.

Landing five adjacent symbols earns you between 0.8x to 0.16x your stake. Spinning 15 or more matching pink symbols yields up to 1,200x your bet. Other two-eyed symbols pay 120x, 240x, and 480x for at least 15 blue, orange, and green symbols, respectively.

Reactoonz also includes special symbols to spruce up your gaming experience. The game features a Wild (multi-colored portal) that replaces all symbols to create a winning combination.

Another special symbol in Reactoonz is the Gargantoon, a three-eyed alien symbol you can activate through the Quantum features. The symbol adds a 3×3 wild to the grid that substitutes for all symbols, significantly increasing the chances of landing winning clusters.

Reactoonz Game RTP & Volatility

Understanding a slot game's RTP (Return to Player) and volatility is crucial for every player before spinning the reels. These metrics play a significant role in determining whether a game aligns with your bankroll and complements your preferred style of play.

The Reactoonz RTP is 96.51%, slightly surpassing the average for slot games (96.0%). This percentage indicates the proportion of wagers you can expect back when playing Reactoonz over the long term. For instance, you can expect $96.51 for every $100 you stake over the long term.

Moreover, Reactoonz has a high volatility score. This means that you may encounter extended gaming periods without landing a win, but it's more likely to be significant when you do.

The slot volatility score is befitting for gamers who enjoy the thrill of hunting for lucrative rewards, don't shy away from calculated risks, and relish the adrenaline of unpredictable outcomes.
