Tatamibari — 畳ばり — is a Japanese tiling puzzle about cutting a floor into mats.
Tap a symbol to take up its mat, then drag from one corner of the rectangle to the other to lay it. Tap a cell again to take it back out. Hold a cell to empty it, or hold a symbol to strip its mat back to bare.
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.
