You will be awarded with 3 respins and a minimum of 4 symbols. During the Bonus, Blue Zeus will cover reel 1 if Lightning Respin is active, or Gold Zeus otherwise. If Lightning Respin is active and Blue Zeus lands on all positions of reel 1 or More & Better or Zues More Power Up and Lightning Respin is active with Gold Zeus lading on 6 or more positions on reel 1, then this bonus will be triggered.
For the sake of this article, I will refer only to Zeus. This bonus is the same for each slot, the only difference being Blue Zeus is Blue Kronos for the Kronos slot, and the same with the Gold.
