Your objective

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.

Work through the instructions

  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

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.

A useful example

Take a moment to check the current turn. 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.

Pay attention to this rule

Check the rule below as you play. 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.
