Input guidance
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. Keep the goal in mind before your next move.
Follow the example
Begin with the basic rule, then follow the result of your 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.
One detail worth checking
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. Try the rule on the board, then read the next instruction.
