Rings Battle is is one of the battle mode competitions in Sonic Rivals 2 played in Act 2 of every zone. During the story, most of the characters (with an exception of Shadow and Rouge) play this battle mode against their rival in Act 2 of Frontier Canyon Zone.
The objective for the player is to simply collect more Rings than their rival within a time limit. Each time the rings are collected they will respawn after a few moments. Each character has a bar near their face on the screen. When a character collects rings if he/she has more rings than his rival the bar will be filled toward him/ her or else the rival's bar will be decreased. The player can reduce their rival's Rings using Signature moves, attacks and Power-Ups.
In Free Play, the player is able to set the time limit for 0:45, 1:30, or 3:00.
