Goal

Find and solve the hidden riddle by filling in squares.

How

Numbers indicate groups of squares in that row or column to fill in. One or more unfilled squares separate groups.

Method

Click a square once to fill it, twice to mark it definitively unfilled (it will turn gold), and a third time to clear it.

Riddle

Unfilled squares spell out the riddle, the first and last letters of which are also the first and last letters of the answer.
