Hitori is a logic puzzle on a grid of numbers. Shade squares until no number appears twice in any row or column among the squares left unshaded, with two catches: shaded squares can’t touch side by side, and the unshaded squares must all stay joined up. New to it? Start with the rules, which solve one of the game’s own puzzles step by step, or play a 5×5 right here.
