Hitori Puzzle - Number Logic

Hitori is the classic Nikoli-style logic puzzle: shade the duplicate numbers so that every number is left alone in its row and column. From lilygames.

● 150 hand-verified puzzles from easy 5×5 to hard 12×12
● Every board is solvable by pure logic with a unique solution
● One-tap controls: white → black → circle (a "surely white" memo)
● Undo and redo freely — settled mistakes glow red right away
● Ads only after you clear a puzzle, never during play
● A new Daily Puzzle every day, with a day-streak counter
● No lives, no energy timers — works fully offline

Only three rules:
1. No number appears twice among the white cells of a row or column
2. Black cells never touch side by side
3. All white cells stay connected as one area

A quiet board, ink and vermilion. Take your time.
