As you complete the game and it’s various phases you’ll notice your save game file has stars on it. Consult the chart to get all the stars!
|1||Complete the game up to World 8. You can skip worlds using the secret Warp Pipes on Worlds 1 and 4.|
|2||Collect all Green Stars in the first eight Worlds.|
|3||In addition to the requirements for the first two stars, you must complete World Star, World Mushroom, and World Flower.|
|4||Collect all stars in the first 11 Worlds of the game.|
|5||Including all previous requirements, the following must also be accomplished: Complete all stages in the first 11 Worlds by reaching the top of the Goal Pole, complete every stage with every character, and collect every Green Star and Stamp in the first 11 worlds. The moment you reach World Crown, youve earned your five star rating!|
Where are the last stamps?
When you complete the game you’re likely missing some Stamps. That’s because each character is awarded a Stamp for beating every level, a total of 5 Stamps. If you beat the entire game with just one character you’re likely missing 4 Stamps. This is simplest to complete using Multiplayer or completing a level and phasing in the remaining characters at the end so they all touch the Goal Pole. You can monitor this status by pressing Select and checking the Worlds.
