FAQ

Q. How is a puzzle's difficulty determined?
A: This can be tough to determine, as one person's "medium" is another person's "easy". But generally, the puzzle is tested for a number of different solving techniques, to see which techniques are required in order to solve the puzzle. If the puzzle requires complex techniques in order to solve it, then it's deemed a tougher puzzle.
