  • Excellent in-game bonus features
  • Wonderful betting range
  • Top-quality graphics and animations
  • The perfect foundation theme for numerous gamers.
  • Cascading wins
  • High variance level
  • Lower-than-average RTP rate


Unlike most online slot games that use reels and rows, Reactoonz stands out with its unique setup. Instead of reels, there is a 7×7 grid where symbols appear and wins are formed. This means that Reactoonz does not have any paylines involved in its gameplay.

To win in this Play’n Go release, you need to create clusters of five or more identical aliens on the grid. These clusters can form in horizontal or vertical areas, but not diagonally. The first step to begin playing is to place a bet. Play’n Go is recognized for designing slots that are easy to access and play.

Once the slot is loaded, you will notice different bet amounts displayed at the bottom of the screen. To select your wager, simply navigate through these options. Arrows on either side allow you to view different values, starting from the minimum of £/$/€0.20 per spin. The bet amounts gradually increase through various stages until reaching a maximum of £/$/€100 per spin.

Just like other online casino slots, the game begins once you choose your desired bet. Click the green button located at the bottom-right corner to set the reels spinning. Alternatively, you can use the yellow button next to it for the autoplay feature, which allows the reels to spin automatically for up to 100 consecutive rounds.

In order to receive a payout, you must form a cluster on the grid by matching five or more alien symbols. Each symbol offers its own payout, allowing you to potentially win up to 750 times your initial stake during the base game round. A winning cluster can be achieved when the symbols touch either horizontally or vertically.


No need for imagination anymore! Play’n Go has brought the xenomorphic creatures from an alien planet straight to your screen in the Reactoonz online slot. Witness the intelligence of these extraterrestrial lifeforms as they generously offer monetary rewards.

The backdrop of space sets the stage for the symbols grid, where deep blues and purples create a dark color scheme. Every so often, flickers of light from distant stars add an extra touch to the slot’s base theme, capturing more attention.

As you glance to the right of the game’s reels, a large alien sits comfortably in its own vehicle resembling a flying saucer. Don’t worry, this extraterrestrial being is well aware of all the happenings in your gameplay. And there’s even more to come from this intriguing character!

Released in 2017, Reactoonz showcases Play’n Go’s signature exceptional graphics and animations. As a result, it has become a popular addition to the game selections of top international casino platforms. The developer’s stunning visual craftsmanship can be seen in every symbol displayed on the grid.

Each symbol possesses its own unique personality, providing endless entertainment from the moment you begin playing. The grid includes symbols and their corresponding payouts displayed in the following formats:

  • The Pink Alien symbol can award a payout of up to 750 times your total bet if you land 15 or more of them.
  • The Green Alien rewards players with payouts of up to 300 times their total bet when they match 15 or more symbols.
  • The Orange Alien symbol has the potential to award a payout of up to 150 times your total wager when you land 15 or more of these symbols.
  • The Blue Alien symbol has the potential to award a payout of up to 75 times your total bet for 15 or more symbols.
  • The Purple Alien symbol has the potential to award a payout of up to 10 times your total bet when you land 15 or more of them.
  • The Red Alien symbol has a potential payout of up to 10 times your total bet if you match 15 or more symbols.
  • The payout for 15+ symbols of the Dark Green Alien is a maximum of 3 times your total wager.
  • The yellow alien awards a maximum payout of 3 times your total bet for 15 or more symbols.

Additionally, it is crucial to note that when four standard symbols match in a square formation, they instantly create Giantoonz. If these symbols are part of a cluster, the wins are doubled.

Design and User Experience

Not only does Reactoonz boast a remarkable overall design, but it also showcases the developer’s renowned mastery in graphics and animations. However, the game’s appeal extends beyond its visual elements.

As you place your bets (and emerge victorious), the game treats you to a delightful symphony of sounds. Imbued with a sci-fi essence, every auditory experience immerses you in the theme. Occasionally, the ambiance is elevated with the inclusion of otherworldly alien creature noises.

When you begin to accumulate wins and activate the slot’s special features, the excitement reaches a whole new level. These elements not only enhance the theme, but also offer limitless amusement. Play’n Go has undoubtedly created something extraordinary with Reactoonz.

Reactoonz Bonuses and Free Spins

Although the Reactoonz game lacks features such as scatters or base wilds, it is not devoid of any special aspects. On the contrary, it offers a plethora of unique features for players to experience and enjoy.


If the game does not result in a win initially, there is a possibility for the Gargantoon, the enormous extraterrestrial character positioned on the right side of the grid, to introduce between four and eight wild symbols onto the grid. These wild symbols have the capability to replace all other regular alien symbols in the game, increasing the potential for winning combinations.

Quantum Leap

You can find the Quantum Leap meter on the top-right side of the slot. It fills up as you create winning clusters. Once you collect 25 symbols in these clusters, a random Quantum feature gets added to the line. You can line up to four Quantum features, and they activate when there are no more wins. The available features include:

  • The ability to implode is a game feature that can convert 3 to 6 symbols into wilds while eliminating all neighboring symbols.
  • Demolition obliterates every single symbol of one-eyed aliens.
  • The incision action carves a wild symbol in the middle of the grid, forming two intersecting diagonal lines across it.
  • When activated, Alteration randomly selects a symbol representing a one-eyed alien, causing all identical symbols to transform into a different symbol.


When the Quantum line on the meter reaches the Gargantoon, a wild symbol in the size of 3×3 emerges and positions itself randomly on the grid. As cascades occur, this symbol splits and shifts, transforming into two wild symbols of size 2×2, and eventually into nine separate wild symbols.
