A walkthrough of the rules
- 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.
Making selections and moves
Begin with the basic rule, then follow the result of your action. 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.
A useful 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. Start a new round when you are ready to try again.
Notice this detail
The value is the position in the row or column, not a uniform count of marked squares.
