The Flash is a side-scrolling platformer starring D.C. comics hero with the same name. The game is divided into six rounds, each round having two stages and a boss fight. Within each stage, Flash must get to the exit before time runs out, though the exit first needs to be unlocked by activating a switch.
The gameplay has similarities to Sonic the Hedgehog, as levels have a complex structure with different passages and many optional areas. Flash moves very fast in general, but can move even faster with SuperSpeed, as long as the necessary energy is not drained.
Flash's SuperSpeed energy is also used for vibrating attacks and can be recharged at Star Food vendors scattered throughout the levels. Vibrating attacks can destroy blocks, some of which contain traps or power-ups, and bad guys. Flash also has a spin attack that can be used to get rid of bad guys while moving.
