Game rules

Reactoonz plays out across a 7x7 grid – something that we’re quite used to seeing from Play ‘n GO. It operates on a Cluster Pays mechanic, spinning up a whole range of modifiers that can greatly increase your chances of winning big cash prizes.

Reactoonz symbols

It’s the game symbols that make Reactoonz such a fun and quirky game to play. Funny little one-eyed aliens represent lower value symbols, with four two-eyed aliens delivering bigger prize payouts. The game generates Wilds from targeted one-eyed aliens who feature in winning spins. And there’s a massive Gargantoon sleeping to the side of the reels, who can wake up and generate additional chances to win. Every winning combination contributes towards the Quantum Features, which introduce Candy Crush-style explosions into gameplay!

Min/Max wagers & lines

You don’t have to bother about paylines when you play Reactoonz, as this is a Cluster Pays game. Match up five or more symbols horizontally and / or diagonally to win cash prizes. You’ll need to wager 20 coins on every spin, which costs from 20p to £100 per game.

Pay table & bonus rounds

The amounts you could win from matching between 5 – 15 symbols in Reactoonz are as follows, shown as multiples of your total stake:

  • Orange and green one-eyed aliens  =   0.1x – 3x
  • Red and purple one-eyed aliens  =  0.15x – 10x
  • Blue two-eyed alien  =  0.5x – 75x
  • Orange two-eyed alien  =  0.6x – 150x
  • Green two-eyed alien  =  0.8x – 300x
  • Purple two-eyed alien  = 1x – 750x

Reactoonz doesn’t just look interesting – the game is packed with bonus features, so it’s worth taking the time to explore a few Reactoonz demo spins before thinking about playing with real money.

Reactoonz bonus features

The huge Gargantoon that sleeps alongside the game has the ability to influence gameplay. Following any non-winning spin he can activate the Instability feature, scattering up to 8 Wilds onto the reels.

The random Fluctuation feature is applied to one of the one-eyed symbols with every spin. Every instance of that symbol appearing in a winning combination triggers a Wild symbol replacement, which could help towards extra winning Clusters.

Groups of four matching aliens two abreast morph into Giantoonz adding a 2x multiplier to any wins they feature in.

Quantum Meter bonus

All winning combinations are displayed in the meter to the left of the reels, and when you’ve collected 25 symbols the Quantum Meter is charged. This sits to the right of the game, modifying the reels as you collect more symbols to action one of four bonus features:

  • Implosion – between 3 – 6 icons become Wild with surrounding symbols destroyed
  • Incision – icons on the two diagonals change to one symbol with a Wild at the centre
  • Demolition – all one-eyed symbols are removed from the reels
  • Alteration – all examples of a randomly-chosen one-eyed symbol are removed and replaced by an alternative symbol

If all four modifiers have been actioned, Gargantoon himself joins the queue. Once he’s unleashed onto the reels he appears as a massive 3x3 Wild, helping to create winning combinations. He splits to become two 2x2 Wilds, before splitting into 9 individual Wilds, potentially generating some big prize payouts.

Animation, graphics, and soundtrack of Reactoonz

It’s the graphics, animations and soundtrack that have helped to make Reactoonz such a hit with slots fans around the world. Cute and quirky game characters really add to the enjoyment, and if you stop playing for a while, they even start chatting amongst themselves - not something you see in standard slots like the one found in our Fruit Party review!

Game features play out much like Candy Crush or Bejewelled, with the Quantum Meter and the Gargantoon spreading explosive reactions across the reels, making for highly watchable gameplay.

Reactoonz RTP and volatility

The Reactoonz RTP comes in at 96%, which is the industry average, suggesting that there are some good prize payouts on offer for some lucky players. But whether you’re considering the Reactoonz slot RTP or the San Quentin slot RTP, this statistic is only part of the picture.

Reactoonz is a high volatility game, making it best suited to high-risk, high-stakes slots players with robust and elastic bankrolls. Smaller wins don’t cover the cost of the spin, so keep a close watch on your balance – ideally, we recommend exploring a few Reactoonz free play spins while you get to grips with gameplay. You won’t be able to keep any winnings from playing Reactoonz demo games, but you won’t end up out of pocket either!

Mobile availability

Lean HTML5 coding means that Reactoonz plays out seamlessly across all your favourite devices. Play on your PC, notebook, tablet or mobile – the game will always look great, and you won’t have to wait endlessly while it loads in your browser either!

Reactoonz verdict

Reactoonz may be aimed at high rollers and risk takers, but it’s such a fun game that everyone needs to give it a try. Particularly as it's from Play 'n GO which is the developer behind the top game featured in our Legacy of Dead review and our Fire Joker review. Don't forget to launch the Reactoonz free play version if you’re not sure how far your gaming funds will stretch. It can take ages to trigger the giant Gargantoon into life, but that’s what every player is hoping to see. And if you end up playing with real cash, that sleepy three-eyed alien has the potential to deliver truly out-of-this-world payouts for some lucky players!
