Perfect Bonus

The Perfect Bonus is a special scoring category in the Sonic the Hedgehog video games. They grant the player special bonuses if he/she completes special requirements in the games they appear in.

Sonic the Hedgehog 2
The Perfect Bonus first appeared in Sonic the Hedgehog 2 where in order to clear a level with it, the player must have collected every single Ring in the level. This does not include any Rings earned from Super Ring Monitors or from Rings placed with Debug Mode. Upon clearing the level, the player gains an additional 50,000 points, the equivalent of an extra life.

Sonic the Hedgehog 3 & Knuckles
The Perfect Bonus later reappeared in Sonic the Hedgehog 3, Sonic & Knuckles and Sonic the Hedgehog 3 & Knuckles where they only appeared in the game's Special Stages. To obtain a Perfect Bonus, the player must collect every single possible Ring in the stage (including Rings formed from Spheres). After that, the player is notified that he/she has a Perfect Bonus and whether he/she successfully collects the Chaos/Super Emerald or not, the player will have a Perfect Bonus category in the score tallying that grants 50,000 points (and an extra life), much like the Perfect Bonus in Sonic the Hedgehog 2.

Sonic Generations
In Sonic Generations, the Perfect Bonus functions differently compared to its previous appearances. The player receives it whenever he/she completes an Act without losing a life. Gaining the Perfect Bonus increases the player's Rank by one level after the score finishes tallying. Hence for the player to attain an S Rank on an Act, he/she must attain an A-Rank and not lose a life.
