Making selections and moves
Read the position before choosing your next action. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board. Keep the goal in mind before your next move.
Learn from a sample situation
Keep the goal in view while choosing a move. 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
The board gives you the information needed for the 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.
