How to use the controls
Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board. Try the rule on the board, then read the next instruction.
Put the rules into context
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. Start a new round when you are ready to try again.
Pay attention to this rule
Read the position before choosing your next action. The value is the position in the row or column, not a uniform count of marked squares.
