See how the rules apply
A careful first move helps you understand the round. 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.
Avoid this misunderstanding
Use the controls beside the game rather than guessing the rules. 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.
