Reactoonz Slot Review

The Reactoonz slot from Play’n Go is an online slot game with a cascading engine and a chargeable bonus feature meter. You can also check out its sequel, Reactoonz 2, but first, let’s dive into the details of this first instalment.

Reactoonz Demo

Watch us spin the Reactoonz reels 100 times in our YouTube demo. It’ll give you a sense of the slot’s gameplay and volatility before risking your own money!

Reactoonz Slot Free Play

If you’d rather try the game out for yourself before depositing real money, you can use the Reactoonz free slot game below. If you’re based in the UK, you may be asked to verify your age first.

About Reactoonz

The Reactoonz slot by Play’n Go takes players on a space adventure across a dynamic 7×7 grid. Unlike traditional slots with paylines, Reactoonz uses a cluster pays mechanic, where wins are formed by landing at least five matching symbols that are touching horizontally and/or vertically.

As there are no paylines in the Reactoonz slot, your bet is the only variable you’ll need to set. The betting range is £0.20 to £100 per spin, making it suitable for budget players and high rollers.

Play’n Go has packed the Reactoonz slot with a wide range of features which I’ll review in more detail below.

What Does The Provider Say?

“Like its prequel Energoonz, Reactoonz is a playful parallel universe charged with stellar power and prizes. Highly animated aliens drop from the heavens and land to occupy the 7×7 game grid. Win a prize for each cluster of 5 or more aliens of the same race: The larger your cluster, the greater your profit!”

How to Play Reactoonz

  1. Set your preferred settings by opening the settings menu (represented by three horizontal lines). Here you can toggle the following settings on/off: Sound, Fast Play, Auto Adjust Bet, Spacebar to Spin. They are all set to ‘on’ by default.
  2. Set your bet amount (£0.20 to £100) by selecting the appropriate figures below the reels.
  3. Press the green spin button. If you have ‘Spacebar to Spin’ enabled in the settings, you can just press your spacebar.
  4. You win by landing five or more matching aliens that are touching vertically or horizontally. Diagonals don’t count.

Symbols

There are eight standard Reactoonz characters – pink, green, orange, blue, purple, brown, dark green and yellow. Little one-eyed aliens offer smaller prizes, while higher-value aliens have two eyes and different horns to make them stand out. The Wild is a vortex.

These critters are all animated, bobbing up and down, blinking, and looking around at the aliens next to them.

A giant three-eyed, multi-horned beast (the Gargantoon) is sleeping peacefully on the right, waiting to be awoken. Each winning cluster transfers energy to the Gargantoon, and when fully charged, it grows and makes a Quantum Leap onto the game grid to release a chain reaction of up to five features.

Features

While playing the Reactoonz slot, you can trigger some exciting features:

Cascading Reels Feature

In Reactoonz, the main highlight of the reel action is the cascading reels feature. It will be triggered whenever you form a winning cluster, and it will remove the participating symbols from the grid. This will make room for new symbols to drop down and potentially form new winning clusters and consecutive wins.

Wild Symbols & Multipliers

Wild symbols don’t appear naturally on the reels. Instead, they can be formed in two ways:

  • On each spin, one symbol is marked as ‘fluctuating’ and starts to glow; if a combo is formed from these symbols, they will leave Wilds behind when they disappear.
  • On any initial non-winning spin, there’s a chance that the Gargantoon will drop four to eight Wild symbols onto the grid.
  • Forming a 2×2 (or larger) square will turn that into a 2x multiplier, affecting any subsequent combos it partakes in.

Quantum Leap Feature

Every time you manage to land 25-symbol combos during standard gameplay, one of the Quantum features can be triggered when the cascades finish. This can come in four forms:

  • Implosion – transforms three to six symbols into Wilds while also destroying all adjacent symbols.
  • Incision – cuts a Wild symbol along the centre and creates two intersecting diagonal lines through the grid, both showing the same symbol.
  • Demolition – destroys all one-eyed aliens and all matching symbols.
  • Alteration – chooses one random one-eyed alien and turns all instances of it into another symbol.

If the Quantum queue reaches the Gargantoon, it will wake up and be added to the reels as a 3×3 wild symbol. The first successful cascade will divide it into two 2×2 wilds, and on the second, it turns into nine individual Wilds. Also, four matching normal symbols forming a square shape automatically form Giantoonz. Wins are doubled in any combo that Giantoonz are part of.

Reactoonz Slot RTP, Variance and Payout

  • The Reactoonz RTP is 96.51%, which is above the industry average.
  • The game’s variance is high, meaning that rewards may not be frequent, but can potentially be more valuable if they land.
  • The maximum payout can reach up to 4,570x your stake.

Other Play’n Go Slots

Play’n Go is one of the leading companies when it comes to developing online slot games. Aside from Reactoonz, some of the most popular Play’N Go slots include:

My Verdict

Reactoonz slot may sound complicated, but it’s really simple once you start playing, and in fact, all of the added features only serve to make it more fast-paced and fun. It’s quicky become a favourite of mine. It also has the potential to be super lucrative with a maximum win potential of up to 4,570x your stake, however so far the high variance model hasn’t benefitted me!

Just remember to never bet more than you can afford to lose and you’re likely to enjoy playing the Reactoonz online slot.
