Shikaku Patches Puzzle - Recto
Daily rectangle brain teasers
Free · Designed for iPad. Not verified for macOS.
1,150 hand-verified boards, from a gentle 4x4 warm-up to an 18x18 expert grid. Every one has exactly one solution, so nothing is ever guesswork. Plays fully offline.
Shikaku is the classic Japanese logic puzzle - also called rectangle division, sikaku, or simply patches. Every grid is scattered with numbered clues. Draw a rectangle around each number so it covers exactly that many squares, then cover the whole board. No arithmetic, no guessing, no time pressure. Just clean logic and the quiet click of a grid falling into place.
Recto gives you 1,150 hand-verified boards, from a gentle 4x4 warm-up to an 18x18 grid that will hold you for a whole evening.

HOW TO PLAY
1. Find a numbered square
2. Drag to draw a rectangle that contains it
3. Make the rectangle's area equal to the number
4. Cover every square on the board, one number per rectangle
That is the whole rule set. The depth comes from the order you solve them in.
