Ready to hang out with some cute-looking little monsters? You’ll be surrounded by one-eyed, two and three-eyed multicolored monsters on the 7x7 grid in Play’n GO’s Reactoonz slot. You’ll enter the lab, where a lot of chemical reactions are happening and doing things in your favor.

The little monsters, the Reactoonz, are actually multiplying on the grid, taking you to the most incredible Cluster wins. The Quantum feature makes the implosion, demolition, alteration, and incision reactions happen and may activate the Gargantoon, where the biggest wins can be won. Be prepared to see some Giantoonz, as well, which makes the slot even more interesting to play. Up to meet the little monsters at the best online slot sites?

If you’re a fan of Play'n GO slots, you’ve probably played the Reactoonz slot since it is one of its most popular slots ever released. Why? Well, because as soon as you load it, you are welcomed into a surreal world, where the little monsters become your friends.

The screen is packed with stuff. On the right, you see one machine which charges every time you land a win. Below it, you see the Gargantoon, which will be explained later. Another meter is on the left of the reels, where your wins are recorded. Below the grid, you’ll find the controls. Going from left to right, you’ll first see the “i” button. It takes you straight to the paytable, where you see the pink, green, orange, and blue two-eyed monsters as the high-paying symbols, delivering wins from 75x to 750x the stake for 15+ symbol combos. They are followed by the purple, maroon, dark green, and yellow one-eyed monsters, the low-paying symbols, delivering 3x to 10x the stake for the top combos.

Next is the Balance display, followed by the bet configuration field, where you can place a bet from 0.20 to 100 credits. The Total bet is recorded in the next field, followed by the Spin and Autospin buttons. The setting buttons are below the “i” button.

If there’s one thing Play'n GO is known for across the online gambling industry is its ability to create the best mobile slots. Reactoonz slot is a mobile slot, so you can rest assured that it will be compatible with any type of mobile device you may own.

Whether you wish to play it at home on your PC or laptop, or you’d want to take it with you when out for a walk, Reactoonz would play the same way and offer the same features. So, whether you have an Android-powered or an iOS mobile device, just load it and enjoy it.

Reactoonz is an unusual slot. In the base game, you benefit from making winning combos with 5 or more symbols, as long as they are touching vertically or horizontally. The winning symbols are removed, and new ones fall to fill the gaps. And the Quantum meter gets charged with each win.

Your wins are recorded on the left meter. But, on non-winning spins, there is a chance for the Gagantoon, the three-eyed monster on the right of the reels, to give you 4 to 8 Wilds on the grid. The Quantum meter needs to be fully charged for the giant monster to give you Wilds on the reels. The Gargantoon appears on the reels as a 3x3 symbol, substituting for each symbol. It can divide and move with each cascade, first as a 2x2 symbol and then into 9 individual Wild symbols.

The Quantum Leap, the one above the Gargantoon, charges with each win you’re making. After winning 25 symbols, a random Quantum feature is added to the queue. These four features are queued, and when you charge the meter for the fifth time, you get the Gargantoon feature. When you trigger no more wins, one of the four Quantum features in the queue will be triggered.

Implosion is one feature, marked with the orange flame, which transforms 3 to 6 slot machine symbols into Wilds while destroying all adjacent symbols. Demolition, the blue fire, demolishes all monsters with one eye and matching symbols, allowing for new ones to land on the reels. The alteration, the green fire, takes a random one-eyed monster and transforms all matching symbols into a different symbol. Incision, the red fire, cuts a Wild into the center and creates two diagonal intersecting lines through the grid, both showing the same random symbol. The Reactoonz bonus game round ends when all queued Quantum features have been triggered, and no more winning combos appear on the screen.

Finally, you have the Giantoonz feature. This is when four regular matching symbols form Giantoonz when adjacent to each other and double your wins. The game chooses a one-eyed monster type at random to be the Fluctuating symbol. If any of these symbols are part of a winning combo, on any spin, they give you 2 Wilds, which substitute for all symbols, taking you to more frequent wins.
