WHY SUDOKU?
Sudoku is one of the most popular logic puzzles in the world, and for good reason. The rules are simple — fill the 9x9 grid so every row, column and 3x3 box contains the numbers 1 to 9 — but mastering it takes real logical thinking. Playing regularly is a great way to train focus, memory and problem-solving skills while you relax.
