The example and rules describe the same game you can play above. Tap cells to mark or clear them. Current totals are displayed alongside the target totals. Start a new round when you are ready to try again.

What counts as success

Use the controls beside the game rather than guessing the rules. Mark cells so every weighted row total and column total matches its clue. The game area remains available above the explanation.

The order of play

  1. A 5×5 grid shows target sums at the right and bottom.
  2. A marked cell contributes its column number to its row sum, and its row number to its column sum.
  3. Tap cells to mark or clear them. Current totals are displayed alongside the target totals.
  4. Match all rows and columns to complete the puzzle. Each generated puzzle is checked to have one solution.

The controls to know

Read the position before choosing your next action. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board.

Work through an example

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. Keep the goal in mind before your next move.

Where a round can go wrong

Check the rule below as you play. 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.
