Reactoonz Free Spins & Bonuses UK 2021

The best Reactoonz free spins bonus is by PlayGrand, where you get £10 + 30 free spins on Reactoonz for £10. Despite not many casinos offering free spins on Reactoonz, most casinos allow players to play Reactoonz slot with their match bonus.. This is a list of our favourite online casino UK where you can play Reactoonz slot.

reactoonz free spins

PlayGrand offers up to £300 + 30 free spins for Reactoonz on first deposit with £10 min deposit.

As long as the casino terms and conditions don’t explicitly say that Reactoonz isn’t eligible for playing with casino bonus funds, you can spin for free using your Welcome Bonus. You could potentially use the entire bonus match to spin on Reactoonz. Max Bet is £100 on Reactoonz, but often casinos licensed and regulated by UK Gambling Commission limit how big you can go with your casino bonus funds.

Best Reactoonz Casino

PlayGrand is our favourite spot to settle in and play Reactoonz slot. The casino offers 30 free spins on Reactoonz, and you can use your matched bonus funds (up to £1,000) to play the game. If you would like to play Reactoonz free without depositing, then please take one of our no deposit free casino money offers, and use that money for Reactoonz free play.

There are a few more reasons we would recommend PlayGrand. The online casino has a more-than-fair payouts and wagering limits and the casino games selection is impressive from slots to bingo.

Payouts and Wagering Limits

While the specific play-through requirements depend on the Play’n Go Casino you’ve chosen, on average the wagering requirement on slots is somewhere around 35x.

In terms of the wagering limits, players can bet anywhere between £0.20 (min bet) and £100 (max bet) on each round. They can also choose from 15 different coin values, ranging from 0.01 to 5.0.

Reactoonz Slots Review

There are very few online slots available in 2021 that are as unique as Reactoonz slot. This real money game created by PlayN GO casino game provider is set in outer space and features colourful aliens across the game 7×7 grid.

The unique intergalactic theme isn’t the only thing that makes the gaming experience of this video slot exciting. Here are a few more Reactoonz features that we love:

  • Untraditional 7×7 grid reel design that keeps things interesting
  • Possibility of consecutive wins with cascading reels
  • Option to play Reactoonz at tons of British gaming providers
  • 5 bonus features for even more winning potential
  • Bet-placing flexibility with over a dozen coin values

Reactoonz Free Play

Some British casinos like LeoVegas allow you to try the game for free. The Reactoonz free play is a perfect way to test the slot demo and get a feel for the game mechanics in the demo play. With the demo play you can test the slot demo before depositing and playing with chance to win real money.

reactoonz slot

Reactoonz is a a sci-fi parallel universe themed slot that awaits with fantastic multipliers!

Reactoonz Slot Gameplay

The Reactoonz slot game strays away from the usual 5-reel design with its 7×7 grid layout. The gameplay is dynamic, the visuals are beautiful, and 96.51% return to player (RTP) makes this a high-variance game. What we love most is the game’s unconventional cluster-pay system and multiplier symbols which determine the game’s winning potential.

To play the game start by setting your bet amount and coin size. Once everything looks in order, just click the Spin button. Players can also skip the Spin button and instead press the Autoplay button, which keeps the Reactoonz online slot spinning without interruption.

reactoonz free play

Trigger the alien monster, Gargantoon, to get 1×1, 2×2 and 3×3 wild symbols.

Symbols Breakdown

You won’t find any of the traditional royal winning combinations, symbols, bars and bells, cherries, or lucky 7s as you spin on Reactoonz slot. Every value symbol is a one, two, or three-eyed critter that hails from outer space. A general rule of thumb to remember is the more eyes, the higher the value.

Coin values can alter from small stakes up to £100. The winning value depends on the number of matching symbols (aliens) that land in a cluster (5-15+). Depending on how many symbols on the reels lands in the cluster, the higher-paying two-eyed aliens can get you anywhere from 0.5 to 750x your original bet. This is without taking into account the bonus features or free spins feature.

Cascading Reels

One thing we especially love about Reactoonz is its cascading reels. As soon as you land on a winning cluster, the winning aliens will be teleported away and replaced with new symbols, upping your chances multiple winnings in a row in a single round. When you play Reactoonz slot game for real money for the first time, following all the winning combinations takes a bit of time. And the one-eyed alien helps you on the right side adding random wilds to the game.

Quantum Features

Every time a player lands on a winning cluster, energy is transferred to the alien monster, Gargantoon, who sits patiently on the right side of the reels, waiting to be awakened. Quantum leap charge meters show Gargantoon’s progress, so pay attention to these throughout the game.

Each time one of these Quantum leap feature meters becomes charged, a bonus round is activated. Quantum Features and various constantly changing symbols on the reels keep the game interesting. There are 4 main bonus rounds you can trigger the Gargantoon game engine feature in Reactoonz:

  1. Implosion: Transforms 3 to 6 symbols into random wilds symbols, while also destroying all symbols adjacent to each other
  2. Alteration: Chooses 1 random one-eyed symbol, and all matching symbols turn into another symbol
  3. Demolition: Destroys all random one-eyed symbols and all paying symbols
  4. Incision: Cuts a wild symbol into the centre and creates two intersecting diagonal lines through the 7×7 game grid

Reactoonz Jackpot

Reactoonz slot game does not have a progressive jackpot, but if you play your cards right, you have a chance to win over 4500x your initial stake with this exciting video slot. Max win is actually quite high for a slot that doesn’t include a progressive mega jackpot.

Play Reactoonz UK on Mobile

Playing Reactoonz is possible with iOS, Android, Windows, and Linux, mobile and desktop. All the game features and special features are the same whether you play from a desktop or smartphone, so you won’t be missing out on any special features when you plan Reactoonz slot on a smartphone or tablet. When Quantum leap charge meters are full and you trigger the Gargantoon, it looks equally goon on mobile devices.

Conclusion: Verdict on These Intergalactic Critters

Reactoonz is definitely not a mindless video poker game. All the moving parts and bonus features can be confusing at first, but you’ll figure things out quickly. Play’n GO helps you along the way by giving a rundown of each feature as soon as it comes into play on the screen.

This online slots game is a major hit in the UK, and the reasons why become obvious within minutes of spinning. The design is simple yet dynamic, the in-game features keep you on your toes, the volatility is high, and the game is downright fun to play. When it comes to Reactoonz, BonusFinder always says “Yes” to these silly little alien critters.
