How to Play Sonic Chaos

Controls
Left/right: move; down while running: roll; 1 or 2: jump. While still, hold down and press 1 or 2, then release down for a spin dash. Up+1 or 2 starts Tails’s flight or Sonic’s standing dash. Pause pauses/resumes.
Sonic Chaos — About this game
Sonic and Tails race across six zones after Dr. Robotnik steals the Chaos Emeralds. Choose one character for the journey: Sonic can pursue the emeralds through special stages, while Tails offers a different route through the terrain with temporary flight. Both characters can build speed with a spin dash. Rings, hidden routes and timed platforming give each short act more to discover than a straight sprint.
