Show HN: Modulo – A daily spatial reasoning puzzle

Nice job. For reference, these are known as tangram or inlay puzzles.

Growing up we had a physical version of it: a stack of a hundred large cards with progressively more difficult outlines of various shapes along with a bag of simple geometric pieces (triangles, diamonds, etc.). The goal was to fill each outline perfectly using the fewest number of pieces, which was printed on the card.

Nice! Is this meant to promote brain health, or to just be relaxing?

Q. Is it possible to resize the shapes? That wasn't clear to me from the interface, and I had a hard time completing one of the first puzzles without being able to resize.
