## What is Hitori, Deductive Logic Puzzle?

LEARN BY DOING
A short hands-on guided tutorial teaches the rules on tiny boards, one idea at a time, and ends with a puzzle with hints if you get stuck. It runs the first time you open the app, and you can replay it from Settings.

PUZZLES
- Easy pack: ten free 5x5 puzzles
- Medium (6x6), Hard (8x8) and Expert (10x10): ten puzzles each
- Custom: UNLIMITED new puzzles, any size from 5x5 to 10x10, at the difficulty you choose

One purchase unlocks Medium, Hard, Expert and Custom.

THEMES VISUAL ADDITIONS (FREE)
- Eight colorful themes - Classic, Great Wave, Bamboo, Cherry Blossom, Midnight, Ocean, Lavender and Sunset.
- Optional Relief board gives a 3-D look.
- Tilted view leans the board back in perspective.

TO PLAY
- Tap a square to shade it, tap again to circle it (indicate you're sure it's not shaded), and a third time to clear it. Drag to paint several squares at once.
- The Show Errors button highlights a rule break as soon as you make it. Turn it off for a purer challenge.
- Undo, redo and reset, and your game is saved automatically when you leave.
- Best times are saved on your phone for every puzzle you solve.
- Gentle haptics as you play, if turned on.
- Works fully offline.

PRIVACY
No logins, accounts, ads, or tracking. The only network connections are to the App Store, when you buy or restore the unlock or open More Puzzles.

THE RULES
Shade squares until no number appears twice in any row or column. Shaded squares may never touch along an edge (corners are fine), and the squares left unshaded must all join up as one connected piece. Every puzzle has exactly one solution.
