Free Jigoku Puzzles by Krazydad
Jigoku means hell in Japanese...
Jigoku puzzles are also a kind of sudoku puzzle (also called Comparison or Greater-Than Sudoku) in which the clues are provided in the form of jigs, or points between squares that resemble "greater-than" and "less-than" symbols. The jigs indicate if adjacent numbers are greater-than or less-than each other. This is the only information you have to go on, which makes these puzzles hellishly difficult.
My jigoku puzzles are collected in 100 printable booklets covering four difficulty levels. Each booklet contains eight puzzles, instructions, hints and answers. If you like these puzzles, be sure to check out my other puzzles too!.
HOW TO USE THE HINTS
My puzzles contain a page of hints in addition to a page of answers.
The hints are puzzles 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 pretty close.
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.
