Mathematical Brain Teasers: Rossini Sudoku Puzzles - 100 Large Print Puzzles

By Jeff Heldt

Rossini Sudoku is a variation of the classic sudoku. The arrows outside the grid indicate that the nearest three digits in the corresponding direction are in ascending or descending order (the highest number is always in the direction of the arrow). All possible arrows are given, so if there is no arrow, the first three digits do not form an increasing sequence in either direction.
