This is not as daunting as you might think. You need to get every ring in the game (480 in total) but none of them are hidden, and you only need to collect each ring once. So, if you miss a ring on your first runthrough you can collect it in a seperate runthrough, and if you have already collected it you never need to collect it again. Even more helpful is that rings you have not yet collected will glow, while the rings you have already collected will not. If you are missing a ring and are not sure of where it is check for alternate paths. Some levels have a high road and a low road with a ring or two on each path. Most are easier to collect in Black and Blue since you will not automatically skip to the next check point if you fail, but some high roads are easier to reach on easy. If you have collected each ring on the level you will get the Silver Ballsy awarrd for doing so.
