The Goal Ring is an item in the 3D Sonic the Hedgehog games. It is the 3D equivalent of the signpost and ends the stage when a player makes contact with it. Goal Rings are technically Giant Rings, however they are not treated as such as their purpose is to teleport the player to a Special Stage.
There are also Back Rings in Sonic Heroes and Sonic Adventure 2 so you could restart the entire Action Stage if you didn't collect a certain object. They appeared in the same place a Goal Ring would. In Shadow the Hedgehog, they are replaced with Save Point Teleporters.
