Futoshiki ("inequality" in Japanese) is a sudoku-like logic puzzle in an square where the digits 1 to each appear exactly once in each row and column. Some digits and mathematical relations are given as clues. Normally, just greater than (>) and less than (<) are used between squares, but this generator gives some additional options.
