Shikaku: Paper & Ink Logic
Calm logic. One number each.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
One number, one rectangle's area, exactly one solution. Calm Japanese logic with no timer and nothing to lose.
Draw a rectangle around each number so its area matches. There is exactly one way.
Every cell ends up covered, none of them twice. Shikaku is a Japanese logic puzzle with no timer, no lives, and nothing to lose. Drag a box; if it is not right yet, leave it — a half-finished rectangle is a note to yourself, and it costs nothing.
WHY YOU'LL STAY
• A new puzzle every day, the same one for everyone worldwide
• Five sizes, from a 5×5 you finish over coffee to a 14×14 that takes a while
• The easy, medium and hard bands need NO guessing — checked by a solver before a puzzle is ever shown to you, not promised in a description
• Pinch-zoom, so the big boards are genuinely playable on a phone
• A free archive: replay any past day from its seed
• Hints that point at the next real step, never at a random square
MADE TO BE COMFORTABLE
• No timer, no lives, no energy meter
• Two-tap accessible input as well as drag
• Play in English, German, Arabic, Persian or Kurdish (Sorani)
• Proper right-to-left layout and localized numerals
• Fully offline. No account, no sign-up
FREE, HONESTLY
The daily, the archive, streaks and stats are free with light optional ads. Rewarded video is opt-in and only ever buys a hint. No banner ads on the board, ever. One purchase removes ads forever — no subscription, no currency, no energy.
