What you need to achieve
Begin with the basic rule, then follow the result of your action. Mark cells so every weighted row total and column total matches its clue. The game area remains available above the explanation.
Follow these playing steps
- 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.
How your actions work
A careful first move helps you understand the round. 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
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.
One detail worth checking
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. Start a new round when you are ready to try again.
