The aliens are back, and this time they've brought more wilds, a trickier grid and a bit more attitude. Reactoonz 2 is Play'n GO's sequel to the fan favourite, released in 2020 with a bigger max win and a whole new set of features under the hood.
As always, our main focus is RTP, since that number is what actually decides how much of your wagered cash you can expect back over time.
Below you'll find exactly which casinos run the highest RTP setting for Reactoonz 2, so you don't have to go hunting for it yourself.

Paylines, max win and RTP in Reactoonz 2
Just like the original, Reactoonz 2 has no classic paylines. Instead you win through clusters of at least 5 matching symbols connected horizontally or vertically on the 7x7 grid.
The max win has been cranked up considerably to 5,083x your stake, comfortably beating the original's 4,750x.
The top RTP sits at 96.20%, though Play'n GO also offers lower settings down to as little as 84.20% depending on which casino you play at. Picking the right casino genuinely makes a difference over time.
Spin difference in dollars
Curious how much that RTP gap actually means in dollars and number of spins once you compare the different settings? We've done the math for you below.
If you start playing with $200 and bet $1 per spin, we can compare how many spins you get depending on the payout level.
At the highest level of 96.20%, you theoretically lose 3.80% of your bet per spin, which equals $0.04 per spin. That gives you approximately 5 263 spins before your budget runs out.
At a lower payout level of 91.20%, the theoretical loss is 8.80%, which is $0.09 per spin. That means you can spin approximately 2 273 times before the money runs out.
The difference is 2 990 spins between these levels – quite a significant difference when you think about it!
How the game works - the Fluctometer and Quantumeter
Reactoonz 2 builds on the original's cluster and cascade system but adds two new meters that shape the entire feel of the game and keep every spin a little unpredictable.
The Fluctometer picks out one one-eyed symbol at the start of every spin. Win with that specific symbol and the meter charges up, and once it's full, 1 to 3 Electric Wilds get dropped randomly onto the grid.
The Quantumeter charges instead from symbols removed by those wilds, and once it fills through its four stages you get everything from smaller Energoon Wilds to the big 3x3 Gargantoon Wild. Gargantoon then breaks itself into smaller pieces through further cascades and can even hand you an extra 2x multiplier at the highest charge level.
Land several Electric Wilds next to each other and you'll trigger a Wild Pair Explosion, blasting away the surrounding symbols and kicking off yet another cascade. This is usually where the game really starts to take off.
Symbols in Reactoonz 2
There are 8 alien symbols in the base game, plus several different wild variants. The pink alien symbol pays the most, while the one-eyed variants deliver the smallest wins.
| SYMBOL | 5 syms | 15+ syms |
|---|---|---|
| Pink alien (highest paying) | 1x | 500x |
| Green alien | 0.8x | 200x |
| Orange alien | 0.6x | 100x |
| Blue alien | 0.5x | 60x |
| Red alien | 0.15x | 10x |
| Purple alien | 0.15x | 10x |
| Teal alien | 0.1x | 3x |
| Yellow alien | 0.1x | 3x |
There's no free spins round in Reactoonz 2, so every single win comes from the base game's clusters, cascades and chargeable wild features. In a way, the whole game is basically one long bonus round.
