Players control Sonic through side-scrolling stages built around speed, jumps, slopes, springs, and enemy bumps. Each act ends at a goal marker or a boss encounter, with branching paths and hidden routes encouraging replay. Rings serve as health, and collecting 100 grants an extra life. Special stages are accessed by finding the hidden entrance and meeting the ring requirement, where the six Chaos Emeralds can be earned.

Sonic

The blue hedgehog protagonist, built around speed and spin attacks.

Dr. Robotnik

The series villain who engineers mechanical traps and pursues the Chaos Emeralds.

Keep your momentum when possible, but slow down in unfamiliar areas to avoid traps and sudden drops. Use slopes and springs to build speed efficiently, and jump with care at the edge of platforms. Prioritize ring collection for survivability, and search for hidden routes and special stage entrances. Against bosses, learn the attack pattern first and strike during the safe openings.
