How to play
Tatamibari — 畳ばり — is a Japanese tiling puzzle about cutting a floor into mats.
- Divide the whole grid into rectangles. Every cell belongs to exactly one of them.
- Every rectangle holds exactly one symbol, and every symbol ends up in exactly one rectangle.
- The symbol says the shape. A plus means a square, equal in width and height. A vertical bar means taller than wide. A horizontal bar means wider than tall.
- Four rectangles may never meet at a single point, the way four tatami mats are never laid corner to corner.
- a square
- taller than wide
- wider than tall
Tap a cell to hand it to a rectangle. Tap again to pass it to the next one that could reach it, and again to let it go. Hold and drag to sweep a whole run into the same rectangle.
On the name
Tatamibari is 畳ばり, from 畳 (tatami, the rush mat) and 張り (hari, laying or covering). The grid is a floor and the regions are mats, which is where the last rule comes from: a Japanese room is never laid so that four mats meet at one point.
