Special Features and Bonus Mechanics
Volts and Bolts stands out for its creative integration of mad science and explosive bonus potential. The key gameplay enhancements revolve around wilds, stacked symbols, and the standout Dr. Electro Free Games Feature.
Wild Symbols
The wild symbol is represented by a glowing lightning bolt, and it substitutes for all symbols except the bonus symbols. Wilds can land stacked on all reels, increasing the chance of landing full-screen wins or multiple line hits.
Wild symbols often appear in both the base game and the bonus rounds, helping to drive win potential higher—especially when combined with Dr. Electro.
Dr. Electro Bonus Feature
The Dr. Electro Bonus Feature is triggered when three or more bonus symbols land anywhere on the reels. Once activated, players are taken into the heart of Dr. Electro’s lab, where they’re awarded a set of free spins.
During the bonus, a collection mechanic is introduced. When the Dr. Electro symbol appears, it charges the energy meter. As you collect more Dr. Electro symbols, you can upgrade symbol values or add additional wilds to the reels.
Key highlights of this feature include:
-
Symbol transformations, where low-paying symbols can be turned into premium ones
-
Additional free spins granted at certain collection milestones
-
Increased wild frequency the longer the bonus lasts
This progressive-style bonus keeps the tension high, as players feel the momentum build with each collected symbol.
