Distinguish optional worlds, hidden exits and special collectibles.

Standard courses contain Star Coins, while the postgame Star World uses Moon Coins. The ordinary coin total does not tell you which of these are missing.

Use the map to plan optional routes

Mushroom and Flower are optional worlds connected through hidden progression routes. A normal clear may leave their entrance path undiscovered.

Open World Star’s first courses

Defeat Bowser in World 6 to reach World Star. Its first courses sit behind a 90-Star-Coin gate. The courses inside contain Moon Coins, which are separate from the earlier worlds’ Star Coins.

Return with a known objective

Choose a missing collectible or exit before entering a cleared stage. This keeps a collection run separate from an ordinary-coin farming run.

Useful tip

Some map access uses Star Coins. Confirm the game’s prompt before spending or assuming that a coin gate behaves like World 9 in the Wii game.
