How to interact with the game
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.
A closer look at one example
Use the controls beside the game rather than guessing the rules. 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. Try the rule on the board, then read the next instruction.
Notice this detail
Begin with the basic rule, then follow the result of your action. The value is the position in the row or column, not a uniform count of marked squares. The game area remains available above the explanation.
