What the game asks you to do
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.
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.
How to use the controls
Check the rule below as you play. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board. Try the rule on the board, then read the next instruction.
Work through an example
Read the position before choosing your 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. Start a new round when you are ready to try again.
Pay attention to this rule
Begin with the basic rule, then follow the result of your action. The value is the position in the row or column, not a uniform count of marked squares.
