Hitori Number Logic Puzzle

Hitori Number Logic Puzzle is a clean Japanese logic game built around the classic Hitori rules, also known as No Duplicate Puzzle or Black and White Puzzle.

Read the grid carefully, shade duplicate numbers, and keep the remaining white cells connected. The rules are simple, but every move matters: white cells in the same row or column cannot repeat the same number, black cells cannot touch side by side, and all white cells must stay in one connected area.

Features:
- Classic Hitori / Number Logic Puzzle rules
- Pure logic solving with no guessing
- Clean grid-based board for focused play
- Local progress saving
- Calm puzzle sessions for short breaks or longer sessions
- No account required

If you enjoy logic puzzles, number puzzles, grid puzzles, Japanese puzzles, black and white puzzles, or Sudoku-style reasoning, Hitori Number Logic Puzzle gives you a quiet and satisfying challenge.
