Inequality Sudoku Puzzles by Dr Gareth Moore

Inequality Sudoku Inequality Sudoku is a Sudoku puzzle with the addition of greater-than (>) and less-than(<) inequality signs between some adjacent squares. These specify that the number in one square must be greater or less-than than square next to it. The aim is simple: place the digits 1 to 9 into the puzzle grid so that each digit occurs once in every row, column and bold-lined 3 by 3 box, and all of the inequality signs are obeyed. Some digits might already be given - these, along with the inequality signs, constrain the puzzle in such a way that there is only one possible solution, which can always be reached via reasonable logical deduction. Guessing is never required. I can supply Inequality Sudoku puzzles in any size and with a range of possible variations - from Inequality Sudoku-X and Inequality Jigsaw Sudoku through to more esoteric varieties such as Skyscraper Inequality Sudoku(!).
