These win-inducing reels may be triggered randomly or by landing two Tesla coil symbols. When that happens, you get one free feature spin during which you will land two to five reels fully stacked with matching symbols for easier and better creation of winning combinations.


Win seven free games by landing two or more full stacks of scatters. In this phase, the reels that trigger the feature become replicating reels with matching symbols. Land another full stack of scatters to turn the reel it lands on into a replicating one and win three more free games. At the end of the phase, there is a random chance of winning five additional free games. The feature can also be started using the buy bonus option.


This mode is triggered randomly and only in the free games phase. It adds more scatters to the reels before a spin and increases this way the chances of landing fully stacked scatters, winning more free games and generating additional replicating reels.

Light up your portfolio with this powerful slot title with lots of potential!
