12 Sudoku Apps We Recommend

Sudoku is a popular type of puzzle that challenges logic and attention to detail. It’s great for players of nearly all ages.

The goal is to place numbers or other items on a grid such that there are no duplicates in any rows, columns or sections. The most common form of the game uses a 9×9 grid, divided into nine 3×3 sections and challenges players to put the numbers 1-9 into the boxes.

Children’s puzzles (and those for beginners!) can be played on much smaller grids, and some use pictures or other items in place of the traditional numbers. There are tournaments and timed versions for those who enjoy more a competitive play.
