- A marked cell contributes its column number to its row sum, and its row number to its column sum.

How to use the controls
The example and rules describe the same game you can play above. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board. The game area remains available above the explanation.
A useful example
The board gives you the information needed for the next action. Marking columns 2 and 5 in the same row gives that row a total of 7. A mark in row 3 contributes 3 to its column. The game area remains available above the explanation.
Watch out for this
Read the position before choosing your next action. The value is the position in the row or column, not a uniform count of marked squares. Start a new round when you are ready to try again.
