Reactoonz is a slot by Play'n GO, where you'll go on a space adventure and encounter friendly jelly-like monsters. These adorable creatures will help you form winning combinations and charge up an energy orb.
The slot layout is really well put together. The background is a plain dark blue colour, and the music fits well with the lively and surprising visuals. The graphics are quite fantastic, and they were ahead of their time when this slot came out in 2017.
The slot is set on a 7x7 grid. Instead of usual paylines, this game uses cluster pays. This means that when 5 or more symbols land in a pattern, they make winning combinations.
Reactooz has a 96.51% RTP, which is quite an average for UK slots. It's high volatility, so you can expect to hit occasional decent wins.

The game symbols are colourful and have cute cartoon-style designs with different personalities, which make the game screen look really fun. The basic symbols with their payouts are shown in the picture above. The creatures with 2 eyes pay more than the ones with 1 eye.
When you play the game, you want to get clusters of 5 or more matching symbols lined up next to each other either horizontally or vertically. When you win, the symbols that made you win disappear and the ones on top fall down into their place. New symbols then appear to fill in the gaps. This process continues until there are no more new wins.
When 4 instances of the same symbol appear adjacent to each other in a square shape, they merge into one 2x2 Giantoonz symbol.
Such symbols acquire a 2x multiplier value, so combinations containing Giantoonz are doubled.
At the beginning of each spin, a random low one-eyed symbol is marked as a fluctuating symbol. If marked symbols participate in a win, they will leave 2 Wild symbols behind, added to the reels before a cascade.
Randomly, if a spin results in no win, there is a possibility that a random number between 4 and 8 of Wild symbols will be added to the reels for a chance to create a win.
Things get even more exciting in Reactoonz when you activate one of the special bonus features. There are four cool features that can be activated when you get consecutive wins in a single round. If you manage to get five consecutive wins, you can activate the Quantum Leap machine and get multiple bonuses and payouts as follows:
