Hidden Number Puzzles
Unlocking Puzzle Pieces
When the puzzle for an episode is solved, it unlocks a puzzle piece for the hidden number puzzle at the end of the chapter. Once all of the puzzle pieces in a chapter have been unlocked, then the hidden number puzzle itself also becomes unlocked.
Putting It All Together
Drag a piece next to another piece so that the edges match. If they do match, then the pieces will become locked together. Continue until all of the pieces have been attached to form a complete square. The completed puzzle will contain a special number hidden somewhere within it.
