Cross-sums number puzzle: fill 1–9 into white cells so every horizontal and vertical run adds up to its clue, with no repeated digit inside a run. Endless procedurally generated levels with a guaranteed UNIQUE solution, plus pencil notes, combination hints, undo and a custom-board mode from 5 to 12 cells.
Goal: Fill digits 1–9 into every white cell. Each run of consecutive cells must add up to its clue written in a black cell (top-right corner = sum of the row run to the right, bottom-left corner = sum of the column run below). A digit may NOT repeat within one run.
