About Reactoonz

Reactoonz is the original Play’n GO slot classic that introduced the little aliens and Gargantoon to the world.

This is one of the most popular online casino slots ever created and comes with a max win of 4,750x your bet per spin.

A fast-paced cluster pays slot; it is one of the iconic games that established game provider Play n Go as one of the world’s top and leading game suppliers.

But be aware that they also released five different RTP versions, so choosing the wrong one can affect your end outcome negatively.

Gameplay and features

At first glance, Reactoonz can seem a bit messy and confusing, but it’s pretty straightforward.

The primary purpose of this 7×7 cluster pays game is to go on an extended win run where you eventually fill all five bars/meters and then activate the Gargantoon character.

Reactoonz features explained:

Cluster Pays: Wins happen when five or more symbols are connected in a cluster. These symbols are then removed, and new characters take their place. This keeps reoccurring until there are no more wins.

Quantum Leap: Five meters/bars that need to be filled. After each separate meter/bar is topped up, one of four features that help you achieve more wins is randomly activated. Once all five bars are filled, the slot’s main feature, Gargantoon, is activated.

Gargantoon: The three-eyed alien will be placed somewhere randomly on the grid as a 3×3 wild symbol, after that as a 2×2 wild, and lastly as nine 1×1 wild symbols.

Random Wilds: On top of this, Gargantoon can randomly, on any non-winning spin anytime during the game, drop 4 to 8 wild symbols on the grid to help you achieve wins.

Your betting choices start as low as $/€0.20 and go up to $/€100 per spin.

What is the max win on the Reactoonz slot?

As Reactoonz is one of the most played slots, many recorded big wins of several thousand x stakes can be found on YouTube. However, the game’s max win is set to 4,750x your bet per spin.

You need to get ultra-lucky to achieve the biggest and even the max wins. So one of those extended win runs is required to fill up all the Quantum Leap five bars. This is followed by Gargantoon, placed in favourable positions with high-value symbols. Then you can scoop in those massive wins.

Note that there will be times when you manage to activate Gargantoon, but the result can be very disappointing after all the wait. So don’t bank on getting big wins each time the 5 bars are filled.

The Wizards verdict: 5 out of 5 stars

During one of Play n Go’s brainstorming sessions and later when Reactoonz was on the drawing board, they probably could never have imagined how these colourful aliens would turn out to become one of the most played online slots ever created.

Players worldwide and streamers on Twitch and YouTube see Reactoonz as one of their top slots today.

Therefore, you can often find this slot in most casinos’ top lists and lobbies in premium positions.

The Reactoonz slot is fast-paced and feels like something is happening all the time.

However, once you start and get the hang of it, you want to keep going until all those 5 bars are filled, and the Gargantoon character is activated, as that’s where the big wins could be waiting.

Reactoonz is one of CasinoWizard’s all-time favourites and one of the games that changed the way we play and enjoy online slots forever.
