Where to Play Reactoonz 2
Reactoonz 2 RTP and Wagering
The Reactoonz 2 slot game uses a cluster-pay mechanic. It uses a 7x7 grid, with winning clusters being formed of five or more symbols anywhere on the grid.
You can adjust the stake using the +/- buttons at the end of a sliding scale under the reels. The minimum wager is £0.10, and the maximum is £100, giving this a healthy betting range. The Reactoonz 2 RTP is 96.2%. The maximum win in the slot is 5,083x your stake.
Reactoonz 2 Symbols and Audio & Video Design
Play’n Go hit a home run with the design of the original Reactoonz slot, so it should not be a surprise that they have not decided to make many changes. The reels are still borderless, with the Reactoonz themselves making up the symbols. The same futuristic soundtrack plays as the reels spin, with some funky sound effects thrown into the mix.
The highest-paying symbol in the game is the cherry-coloured alien. This serves up wins of 500x your stake if you can land a cluster of fifteen or more. The green alien is next up, paying 200x, with the orange alien third with 100x for combos of 15.

Reactoonz 2 Mobile Features
Play’n Go develops its slots with mobile users in mind, and Reactoonz 2 is no different. The slot game has been fully optimised to work on various devices and operating systems. You will also be able to play it at top mobile casinos that have apps.
Reactoonz 2 Bonus Features
The original Reactoonz slot was loaded with bonus features, and Reactoonz 2 has brought several of them back and added some new ones to the mix.
Cascading Wins
The Cascading Wins feature makes its return. The winning symbols will disappear from the grid and trigger a cascade whenever you land a win in the game. This will then continue to happen until there are no new winning clusters.
Fluctometer
Fluctuating symbols make a return in Reactoonz 2. A random symbol is selected on each spin and operates as the fluctuating symbol. This will glow on each spin. If this is part of a winning symbol, it will create an Electric Wild. When these fluctuating symbols are removed, they are added to the Fluctometer.
Once the Fluctometer has been fully charged, it will add one, two, or three Electric Wilds to the reels.
Quantum Meter
Any non-wild symbols removed by an Electric Wild are collected in the Quantum Meter. As this fills, it will place additional Energoon Wilds and Gargantoon Wilds on the grid. These are both enhanced Wild symbols. A 3x3 Gargantoon Wild will trigger a Cascade. It will then split into two 2x2 Gargantoon Wilds.
Reactoonz 2 Final Thoughts
The Reactoonz slot is one of the best that Play’n Go has ever produced, and while the sequel is not quite as great as its predecessor, it is still a brilliant slot in its own right. The shuffling around of features was a bold move, with some elements working better than others. However, once you get into those bonus rounds, there is so much fun to have here. The boosted win rate is also a bonus, with players able to win 5,083x their stake. On the whole, this is another fantastic slot from Play’n Go.
