Reactoonz is a cascading video slot game played on a 7x7 grid. Symbols drop down in the grid to form winning combinations. Wins are achieved by getting 5 or more symbols in a connected cluster where they touch each other horizontally and/or vertically. Winning symbols are removed and new symbols drop in to fill up the grid. The game continues to cascade until no new winning combinations can be created.
All wins during a game round contribute to increasing the 5 Quantum Leap charge meters one by one. When a charge meter is fully charged, one of the following quantum feature is added to the queue randomly:
Implosion: Transforms 3 to 6 symbols into wild symbols, while also destroying all adjacent symbols
Alteration: Chooses 1 random one-eyed symbol, and all matching symbols turn into another symbol. In case if there are no one-eyed symbols on the grid, feature can choose any available symbol
Demolition: Destroys all one-eyed symbols and all matching symbols
Incision: Cuts a wild symbol into the centre, and creates two intersecting diagonal lines through the grid. Both lines will show the same random symbol.
When all 5 charge meters are fully charged, the Gargantoon feature is added to the queue. The Gargantoon first adds a 3x3 wild symbol to the grid in a random position. If no more cascades are possible, it first becomes two 2x2 wild symbols, before finally ending up as nine 1x1 wild symbol. New symbols drop down from the top to fill the grid before each move.
If no more cascades are possible, the Quantum features in the queue are triggered. The game round continues normally, allowing the charge meters to charge up for more effects, possibly creating additional wins! Charge meters reset only at the end of the game round, if there are no more winning combinations present.
On any initial non-winning spin, there is a chance for the Gargantoon to drop 4 to 8 wild symbols onto the grid.
4 matching normal symbols adjacent to each other in a square shape automatically form Giantoonz. Wins are doubled in any winning combinations if one or more Giantoonz are part of it.
One random one-eyed symbol type is marked as fluctuating symbol in each spin. If any of the marked symbols are part of a winning combination, they leave 2 wild symbols behind. Wilds substitute for all normal symbols!
The RTP is 96.51%.
