Bonus features
Multipliers
Oversized aliens can multiply the prize when they become part of a winning cluster.
Implosion
Turns 3 to 6 random symbols into wilds and destroys the symbols next to them.
Demolition
Destroys all lower-paying one-eyed aliens in view.
Incision
Places a wild in the centre and creates two crossing diagonal lines that reveal the same randomly chosen symbol.
Alteration
Picks a random lower-paying one-eyed alien and turns all of them into another random symbol.
Gargantoon
The fifth charge of the Quantum Leap meter drops a 3x3 wild onto the grid, which splits with each cascade into two 2x2 wilds and then nine 1x1 wilds.
Fluctuation
A random low one-eyed symbol is marked each spin, and each marked symbol in a win leaves 2 wilds behind.
The Quantum Leap meter charges as cascades occur. When it fills, a large wild enters the grid and breaks into smaller wilds during later cascades.
