The Latino Puzzle

The Latino Puzzle is a Latin Puzzle based on Latin squares. Latin squares were studied by XVIIIth century Swiss mathematician Leonhard Euler, who used latin letters instead of numbers, hence the name. In a Latin square puzzle every row and every column must contain all numbers from 1 to 9.

The Latino Puzzle is kindly dedicated to Prof. Raúl M. Falcón Ganfornina, Spanish expert in Latin squares.
