Consecu-doku Puzzles: Sudoku puzzles with a twist

by John Musgrave

This is a collection of 100 large (full page) sudoku variant puzzles. They are called Consecu-doku or consecutive sudoku puzzles. Consecutive means adjacent cells (indicated by circles) must have consecutive values. Adjacent cells without circles CANNOT have consecutive values. The usual sudoku rules apply. Digits 1 thru 9 must appear in each row, column, and box without conflict. These puzzles are challenging but can be solved with brain power alone. All puzzles tested for validity (ie. one unqiue solution).
