Insane sudoku are the hardest sudoku I offer. They cannot be solved without making guesses. I provide an extra scratch area on these puzzles for working out the solution, but it won't be much help!

My printable puzzles contain a page of hints in addition to a page of answers.

The hints are puzzle grids that contain numbers showing the order in which the squares were solved by my computer. Although this is not necessarily the order you would solve the puzzle, it's probably in the neighborhood.

Follow the numbered squares in order 1,2,3,4,5... until you find a square you haven't solved yet. This square (or the one or two immediately after it) is a good candidate to solve next.
