How to interact with the game
The board gives you the information needed for the next action. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board.
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. Start a new round when you are ready to try again.
Notice this detail
A careful first move helps you understand the round. The value is the position in the row or column, not a uniform count of marked squares. Keep the goal in mind before your next move.
