Reactoonz 2 Slot Machine – Free Play & Review

Featuring cute aliens on its reels, tiny creatures that will often come to life and look around, the game takes the recipe of the original Reactoonz, and makes some improvements. Some symbols will be smaller, others reach giant size, and overall it’s going to look very well designed. It’s a big game area, with 7×7 reels, and there is a lot going on there.

Its symbols come in 8 variants for the regular symbols, which will each have a different look and color. With 1 or 2 eyes, where some look like blobs and others like tiny horned devils, they’re cute and interesting to look at, and they constantly move around and do stuff. Bigger variants, like the Gargantoon, also exist.


Play n GO is a prolific developer of slot machines, but what’s even better is that they don’t just clone all the time, they actually bring new features and try to innovate as much as possible. The fact that they incorporate impressive graphics and big rewards in every single game, also adds to the list of reasons why they’re appreciated.

How To Play It

Pick the wager directly, it’s going to be available on the list from the bottom. Scroll to the left or right, as needed, to get to a value ranging from $0.20 to $100.

The game area features 7×7 reels, where wins form through clusters of 5 to 15+ matching symbols. The more symbols that are grouped up, the higher the reward, though it matters what type of symbol is involved as well.

Special Features

Once you manage to form a winning cluster, a chain reaction follows, with winning symbols removed and others landing in the empty positions. For as long as wins keep forming, the chain reactions keep triggering as well.

Wild symbols come in about four different versions, some of them being reserved for other features:

  • Energoon Wild
  • Gargantoon Wild
  • Electric Wild
  • Uncharged Wild (can be turned into Electric Wild)

The Fluctometer is a meter which is charged when a certain symbol forms a combination that round. The symbol which fluctuates is picked at random for each spin. Get the meter filled (11 charges) and you get 1 to 3 Electric Wilds added at random.

The Quantmeter gets charged when an Electric Wild removes non-wilds. This gets reset each round. It can be charged by 55 to get level 1, 85 for level 2, 110 for level 3, and then 135 to overcharge it.

With the Quantmeter up to level 2, you get Energoon Wilds added to the reels by it (4 regular Energoon Wilds at lvl 1 and one 2×2 Energoon Wild at level 2). Level 3 adds a Gargantoon Wild, while level 4 gives you a 2x multiplier as well. As you form wins with these 3×3 Gargantoon Wilds, they break up into smaller symbols (2×2 and then 1×1), but they stick around as you go through cascades.

Finally, you can also have Uncharged Wilds in view, which can be used as substitutes only if they are turned into Electric Wilds by being next to a winning cluster.

Two Electric Wilds, if they’re adjacent, will pair up and explode, destroying neighboring positions.

Maximum Payouts

Payouts are going to get to decent values, over 5,000x the stake even. The potential is present in the game, and the high volatility is paired up with a good RTP, at 96.20%.


Reactoonz 2 continues the interesting mechanics of the previous slot, but now the payouts are improved, and they’ve worked on other aspects of the game as well. They didn’t do much to change the graphics though, to the point where some players might not realize immediately if they’re on the first or second game of the series.
