Your objective
The board gives you the information needed for the next action. Mark cells so every weighted row total and column total matches its clue.
How a round unfolds
- 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
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.
An example before you play
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. The game area remains available above the explanation.
An important reminder
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. Keep the goal in mind before your next move.
