Rules, controls and help for Kakurasu

Generated 5×5 puzzles with an exact row-mask search for uniqueness before publication to the board. No calibrated difficulty labels.

Your inputs
Keep the goal in view while choosing a move. 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
Keep the goal in view while choosing a move. 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.
A useful caution
The value is the position in the row or column, not a uniform count of marked squares. Keep the goal in mind before your next move.
