Doctor Electro slot has a pretty electrifying design, with the doctor himself standing to the left while his colleagues turn within the reels. Initially, there are just 5 reels with 4 rows, but when the Free Spins Bonuses play out, this can increase with the collection of special symbols.
Special expansion symbols illuminate a meter that covers the top 3 positions on that reel. These meters are made up of 1, 2 or 4 positions and come into their own when you trigger the Hyper Spins feature.
The Hyper Spins Feature will be activated when you land 3 expansion symbols on the same spin. You’ll then play 5 Hyper Spins. Any meter position that was filled in the base game then unlocks and becomes active in this feature. Collecting Expansion Symbols during the Hyper Spins can open up more positions. If all the columns reach their maximum height, you’ll be playing on reels that offer as much as 16,807 ways to win.
