How To Play

Alien and Crystal symbols

Landing Alien or Crystal symbols in 2x2, 4x1 and 1x4 clusters of the same type will transform into Mega Symbols. Each transformation increases the Win Multiplier by +1. Each transformation remains as 4 symbols for the purposes of creating winning combinations. The Win Multiplier is capped at 25x.

Boost Meter

The Boost Meter is filled by forming winning combinations. There are 4 stages: +2, +3, +4 and +5. The stages require 25, 60, 110 and 200 symbols respectively involved in winning combinations. Each of these modify how much transformations increase the Win Multiplier by. The Boost Meter is deactivated once the Win Multiplier has reached his cap.


There are 6 Wilds in total; 1 basic, 4 Special and a Mega Sparky Wild. When a Special Wild is involved in a winning combination it is collected and when there are no more cascades, it triggers 1 of 4 features; Mega Symbols are added randomly across the grid. All Crystal Symbols are removed from the grid. Random basic Wilds are added to the grid. A randomly selected pattern of symbols is destroyed across the grid of which some may be replaced with one type of symbol. When 4 Special Wilds have been collected, the Sparky Wild is added to the grid alongside a Wild when there are no more cascades. This can be triggered up to 3 times by repeatedly collecting 4 Special Wilds.

On the first trigger: a Sparky Wild is added along with a Special Wild. On the second retrigger: a Sparky Wild will be added with either a Special Wild or a basic Wild. On the third and final retrigger: a Sparky Wild will be added along with a basic Wild only. On a random non-winning spin, a Special Wild is added adjacent to a transformed Mega Symbol.
