Place the tiles (16) so that there are no overlaps and no gaps. Each tile has only one "home" position (where it does not overlap the grey border, or another tile's space). Click on a tile to bring it to the front layer and rotate it 90° to the right. Tile colors are random. There are no white tiles, so, seeing white means that you are actually seeing the background (empty slot). If there seems to be a missing tile, you can find the tile that you are looking for under another tile (at 90°, 180°, 270° from where it belongs).
<100 blocks mobile-friendly If this attracts enough interest, I may add an 8x8 mode.
