-If you use the \q{Solve} function on this game, it will highlight
-some of the squares with red blobs. If you click once in every
-square with a red blob, the game should be solved. (If you click in
-a square \e{without} a red blob, a red blob will appear in it to
-indicate that you will need to reverse that operation to reach the
-solution.)
