Plus Mark

How to play

1. Drag a block onto the board, or tap it and then tap the cell for its top-left corner.
2. All five cells of the plus must share a hue.
3. Those five cells fade away.
4. Square corners and a straight line stay.
5. The round ends when nothing fits.

About

Place blocks on an 8×8 board. A plus of one hue — a center and the cells above, below, left, and right — disappears. The corners of a square stay. A straight line stays.
