Goal: Fill the white cells with digits 1–9 so that each run of cells matches the clue shown in the black cell beside it.
Clue cells are black with a diagonal line. The number in the top-right is the target for the run going across (right). The number in the bottom-left is the target for the run going down. A small symbol next to the number shows the operation (+ for addition, − for subtraction).
No repeats: Within any single run, you may not use the same digit twice.
Select a cell by clicking it, then click a number on the pad below to fill it in. Click a filled cell and press Clear (or click the same number) to erase it.
Errors are highlighted in red – either a duplicate digit in a run or a completed run that doesn’t match its target.
