Reactoonz review

Theme and Style

This game is themed around adorable aliens on a grid.

Players will enter an alien ship, discovering it is filled with delightful little alien creatures. As these colorful creatures smile, merge, and glow, players will begin to explore their unique world.

This is a great game for players in the mood for an uplifting sci-fi excursion. The atmosphere is light and players will never be so happy they were abducted by aliens.

Visuals and Soundtrack

The music is a classic sci-fi tune filled with theremin notes. Beeps and chirpy gibberish alien voices add an extraterrestrial vibe. Sparkling explosions celebrate wins, ensuring that they feel on theme too.

The reels are filled with a wide variety of aliens of many shapes and colors. Some have one eye, others two, but their unique personalities shine through. Animated in jewel tones, they are especially eye-catching. Best of all, every alien has a friendly smile and seems to be on the players’ side. They definitely seem to be up for some fun and this attitude is contagious.

Beside the reels, a giant alien with three eyes sleeps peacefully, waiting to be woken up for the bonus feature. Behind the giant alien is the dark blue backdrop of outer space. This adds to the feeling that players have hitched a ride, or perhaps have been teleported onto an alien spaceship.

Gameplay and Key Statistics

Reactoonz has seven reels and seven rows. Wins are awarded for landing at least 5 matching symbols provided that they touch horizontally or vertically.

This game offers a return to player of 96.51%, above the industry average of roughly 96%.

The range of bets provided by this game ran from a minimum bet per spin of $/£/€0.20 up to a maximum of $/£/€100 per spin.

With high volatility, this game will award payouts less often, but will tend to land larger wins.

Bonus Gameplay and Special Features

The Wild symbols substitute for all regular symbols. During all non-winning spins, players may receive between 4 and 8 Wild symbols at random.

The Quantum leap is a meter that charges up while players are winning. A random Quantum feature is added after passing 25 winning symbols. As many as 4 Quantum features can be added. When no more wins are present, the Quantum feature or features in the queue will be triggered. The round concludes when every Quantum feature has been triggered and there are no more winning combinations.

The Quantum features include:

  • Transforming a cluster of symbols into Wild symbols.
  • Destroying all lower paying symbols.
  • Adding a Wild symbol into the centre of the game.
  • Transforming lower paying symbols.

After passing 4 features, the Gigantoon feature begins. As the Quantum queue reaches its maximum capacity, an extra large 3x3 Wild symbol called the Gigantoon will appear in the form of an adorable monster.

With each Cascade, this extra large Wild symbol will divide and move on the reels. This begins with the extra large Wild becoming a 2x2 sized Wild, and then with it dividing into nine individual Wild symbols.

Whenever 4 matching symbols appear adjacent to each other, forming a square, they will merge to a Giantoonz.

The lack of a Free Spins feature is a little disappointing, but Reactoonz makes up for this with its variety of other unique Bonus features.


We recommend this high RTP, high volatility alien-themed slot.

With its ample RTP and strategy-friendly volatility, this game is a great choice for strategy-minded players.

The colorful and irresistibly cute animation make this game fun, while the whimsy of the sci-fi theme is well-executed. Meanwhile, the variety of Bonus options add further appeal and ensure that players stay engaged.
