Red Rings are collectible items found in Sonic Colours and Sonic Generations. They exist as hidden items in the game's Acts.
Colours was the first Sonic game to feature collectable red rings, and collecting them will unlock new levels in Game Land, The same concept was employed in Sonic and the Secret Rings, where Fire Souls (usually three per stage) could be grabbed to unlock extra Storybook pages or multiplayer modes.
