The challenge in front of you
Keep the goal in view while choosing a move. Mark cells so every weighted row total and column total matches its clue. Try the rule on the board, then read the next instruction.
How to proceed
- 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 interact with the game
Use the controls beside the game rather than guessing the rules. Tap a square to mark or clear it. Undo restores the last state. New puzzle generates another checked board. The game area remains available above the explanation.
Put the rules into context
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. Try the rule on the board, then read the next instruction.
One detail worth checking
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.
