[edit] Hints

Hint One
    Don't be confused by the complex shapes of the blocks. Try comparing the frame and the blocks from a different perspective.

Hint Two
    Filling in the frame with the correct five shapes can be pretty tricky. But there's a way to identify the surplus block without worrying about the shapes at all!

Hint Three

Super Hint

[edit] Solution


Circle the shape as shown.

[edit] Progress

1085 Picarats and 129 Hint Coins.
