Making selections and moves
Take a moment to check the current turn. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board. Start a new round when you are ready to try again.
Learn from a sample situation
Check the rule below as you play. 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.
An important reminder
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.
