Questions
Good to know.
Does every puzzle have one solution?
Yes. Foldio checks each puzzle as it makes it, and only keeps those with exactly one solution.
Is it suitable for children?
The 4 × 4 and 6 × 6 grids are made for beginners, and you can print one to a page so the squares are big enough for young hands.
