Sudoku desafía tu mente

Sudoku is "a puzzling global phenomenon."

"Sudokus are to the first decade of the 21st century what Rubik's Cube was to the 1970s." (The Daily Telegraph)

These addictive puzzles are easy to explain, just fill the grid with numbers according to the few simple rules, but incredibly fun and engaging to complete. You don't need any mathematics knowledge. Just supply a pencil and an inquisitive mind.
