Lots Sorted

Place tetrominoes by shape and keep any row from filling with four black cells.

Controls

Shade cells so every enclosed region contains a four-cell tetromino. No row may contain four consecutive black cells. Two tetrominoes with different shapes may not share an edge, while equal shapes must connect through shared edges into one group. Tap cells to shade or clear them, then use Clear and the answer button.
