Unlockable - Advanced Puzzles
To unlock all Advanced Puzzles, you must first clear the first 60 Basic Puzzles. "Clearing" a puzzle means without using hints; a star marked next to Puzzle Selection states that the puzzle was cleared. However, if you use hints, remember where they are and then restart the puzzle via the Pause Menu. It would make the clearing much easier, and less brain work would be needed.
