Aim for this result
Check the rule below as you play. Mark cells so every weighted row total and column total matches its clue.
From the start of a round
- A 5×5 grid shows target sums at the right and bottom.
- A marked cell contributes its column number to its row sum, and its row number to its column sum.
- Tap cells to mark or clear them. Current totals are displayed alongside the target totals.
- Match all rows and columns to complete the puzzle. Each generated puzzle is checked to have one solution.
Getting comfortable with the controls
Use the controls beside the game rather than guessing the rules. 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.
See the idea in action
The board gives you the information needed for the next action. 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. Keep the goal in mind before your next move.
Where a round can go wrong
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.
