Reactoonz by Play’n GO takes you on a space adventure like no other slot online. Realized in 2017, this alien-themed slot uses a cascading game engine and is playable on a 7×7 grid. Known to be highly volatile, a player can win up to 4,570 times one’s stake on every cascade.

Also, since Reactoonz is a slot perfectly optimised for any mobile casino app or its web browser counterpart, it should come as no surprise that some operators use it for their no wagering slots bonuses and other promotions. It is also worth noting that the minimum deposit requirement is usually the lowest with Pay by Mobile slots, and Reactoonz is not an exception.

Stay tuned as we break down all the important aspects of the video slot that is frequently ranked as one of the most popular among UK players.

Reactoonz Slot Rules and Combinations

Like its predecessor Energoonz, the Reactoonz slot also features what we know as cluster mechanics. It doesn’t have classic paylines like most other best payout online slots. Here, the masterfully crafted alien characters fall from above to fill the positions on the reels. If they happen to be a part of the winning cluster, they are teleported back to the galaxy straight away, clearing the path for incoming fellow extraterrestrials that can continue the winning streak.

Bet Level and Coin Value

The betting levels on the Reactoonz slot machine range from 20p to £100 per spin — sums that can easily appeal to a wide spectrum of fans. If you belong to a group of more prudish players, you can even take advantage of the demo version of the game.

The maximum bet in the slot is £100 per spin.

Spin and Autoplay

After you’ve selected the bet value, the only thing that remains is to hit the Spin button, and the action will be underway. Of course, pressing the button repeatedly can become quite boring, so the handy little autoplay function lets you instruct the machine to play through up to 100 spins for you automatically.

Reactoonz Slot Winning Symbols and Their Values

Wacky, animated aliens land on the 7×7 playing grid to form cluster wins. The goal is to link as many of them as possible for some massive wins. If you manage to string prize-winning clusters of 5 or more aliens of the same type, high-paying bonus rounds are bound to come flying your way. With its four different bonuses, Reactoonz Quantum Leap feature joins forces with the peculiar Gargantoon to help you claim the ultimate prize — 91,406 coins or 4,570x the bet.

RTP and Volatility

Online casinos offer a demo option so potential players can play for free and find games that suit them. This way, you can get the hang of the game and see its superb 96.00% RTP and high variance in action. If you come to play with real money, you should be aware that it is considered to be a high volatility game.

Bonus Options and Tips to Play

Reactoonz offers bonus rounds, and they are nothing short of spectacular. Gargantoon, the king of the aliens, is your key to big payouts. He can add between 4 and 8 wilds on the reels after the initial non-winning spin and help you turn things around.

Every time you score a win, the energy is transferred to Gargantoon, who is building forces for the invasion. The Quantum Queue accumulates with every successive win. Once you link wins with 25 symbols, a Quantum Feature block will finish charging.

Up to 4 blocks can be charged with enough winning combos and added to the queue. After there are no more linked combos, the bonuses are activated and can transform random symbols into a single one, destroying others to make way for new symbols and bigger wins and bringing many other perks along the way.

If you manage to charge the energy block for the fifth time, a special Gargantoon feature is triggered. The monster appears as a wild in 3×3 size and moves across the grid to boost the payouts.
