How Spark of Genius works

Tess brings Gyrota, which rotates three to seven symbols, and Dynamo, which gives control of up to six connecting special symbols. Her Free Energy Spin builds a Win Multiplier with each win. Maynard's Relay destroys random symbols and Overload adds up to six symbols that dismantle their surroundings. His Empire Energy Spin uses a 2×2 connector to raise the multiplier.
