While collecting rings is essential for survival and extra lives, a dedicated side activity for completionists is to try and collect every single ring in each act. This often requires thorough exploration of every path, including hidden areas, and careful navigation to avoid losing rings. Collecting all rings in a stage is a significant challenge that tests your knowledge of the level layout and your ability to control your character precisely. It often means sacrificing speed for exploration, making it a different kind of challenge than Time Attack. Certain characters excel at this more than others; Tails' flight and Knuckles' climbing abilities are particularly useful for reaching obscure ring caches. Amy's Hammer Attack can also reveal hidden rings by breaking certain obstacles. Achieving a perfect ring count in every stage is a testament to your mastery of Sonic Advance and its intricate level design.
