Your goal is to fill in the grid to form a picture.
Left-click to fill in a square.
Right-click to mark a square as empty.
Unsure? Use middle-click to mark a square as a maybe!
You can also use the buttons below the grid to change mouse modes. The X turns left-click into X-Mode, while the ? turns left-click into Maybe-Mode. The cursor returns the mouse-mode to normal.
The numbers on the side and top tell you how many squares in that row or column are filled in.
Numbers separated by a space mean that there is at least one empty square between the sets of filled in blocks.
*hint* If the number is the same size as the grid, the whole row or column can be filled in!
