Reactoonz 2 is a Play’n GO release from 2020 and a sequel to the wildly popular Reactoonz slot. It delivers the same exciting action and alien theme, improving every aspect of the original title.
The colourful cast of extraterrestrials make up all the paying symbols in the Reactoonz 2 slot. The game also has four wild symbols, with some only appearing during their associated features. Wild symbols are depicted as two aliens and two electric orbs.
Reactoonz 2 Slot Basics
The Reactoonz 2 slot uses a 7×7 layout with a cluster pays mechanic, which requires you to make clusters of five or more identical symbols to make wins. It also has an RTP of 94.20% with high variance, so payouts occur less frequently but are usually larger. Your minimum and maximum wagers per round are £0.20 and £100, respectively. Additionally, the top prize in Play’n GO’s release is 5,083x your total stake.

The highest-paying symbol in the Reactoonz 2 slot is the pink alien, which awards £100 for a cluster of five symbols, £200 for a cluster of six icons, £300 for a cluster of seven symbols, £500 for a cluster of eight icons, £800 for a cluster of nine symbols, £2,000 for a cluster of 10 to 11 icons, £5,000 for a cluster of 12 to 14 symbols, and a maximum of £50,000 for 15 or more icons.
The bright green alien is the next highest-paying symbol, granting up to £20,000. After it are the orange and blue aliens, worth up to £10,000 and £6,000, respectively. The purple and red aliens pay up to £1,000, while the dark green and yellow aliens award up to £300.
Special Features
The Reactoonz 2 slot comes with several special features, including cascading reels, which are triggered with each winning cluster. When this happens, all winning symbols are destroyed, and existing symbols fill the empty spaces while new ones appear from the top of the grid. The new symbols can form more wins, continuing the reaction until no more new wins are made.
There’s also the fluctometer feature, where one low-value alien icon is chosen every round to become a fluctuating symbol. Wins with these icons create electric wild symbols and fill the fluctometer. Filling the fluctometer adds up to three electric wild symbols to the playing area.
There’s the quantumeter, which is charged when non-wild symbols are removed by electric wild symbols. The meter has four charge levels and holds up to 135 charges, with each winning icon equalling one charge. You need 55 charges for level one, 85 for level two, 110 for level three, and 135 for level four.
If the quantumeter doesn’t reach the third level, it awards energoon wild symbols. Level one adds four 1×1 energoon wild symbols to the grid, while level two adds a single 2×2 energoon wild symbol. From level three, the Quantumeter adds a single gargantoon wild symbol. On level four, a 2x multiplier is applied to all wins including gargantoon wild. After participating in a win, the 3×3 gargantoon wild symbol splits into two 2×2 wild symbols, which then split into nine 1×1 wild symbols if they are part of another cascade.
The Reactoonz 2 slot also has the wild pair explosion feature, which is triggered when all features are done and there are two or more electric wild symbols remaining. If there are two adjacent electric wild symbols, all other symbols except other wild symbols are removed.
If there are non-adjacent electric wild symbols, symbols between them and their surrounding symbols are destroyed excluding other wild symbols. The symbols removed do not contribute to the quantumeter.
Uncharged wild symbols can appear on any cascade and do not form wins. However, if one such wild is adjacent to a winning cluster, it transforms into an electric wild symbol. Uncharged wild symbols can also change into electric wild symbols if the wild pair explosion feature is activated.
