As you are successful on the grid, the quantum leap meter charges up, and after 25 winning symbols, a random quantum feature is added to a queue. Once the queue is full, the Gargantoon feature is triggered, offering a chance to replace non-winning symbols with one-eyed symbols and all matching.

A simply revolutionary slot! I believe the people will talk about decades later. This what it means for industry.
Action, action, action, explosions and big fun – these are what the slot is about. It’s very unpredictable and keep you interest sky-high during every spin. Of course, the must satisfying part is when you get the combo of wins to complete the meter. That’s where a real action begins!
If you are yet to play this slot, do it. It’s an all-time classic.
