Fill each run of cells with distinct digits 1–9 that add up to the clue. Three difficulties, notes, hints, and a timer.

How to play

Goal: fill every run of white cells so its digits add up to the clue.
A clue sits in a black cell: the top-right number is the sum of the run to its right, the bottom-left number the sum of the run below.
Use the digits 1–9; a digit may never repeat within the same run — clashes turn red.
Tap a cell, then a number (or use the keyboard). ✎ pencils candidates, 💡 reveals a cell, ⌫ erases.
A few cells are given to start. Switch Easy / Medium / Hard any time.
Faster solves with fewer hints score higher.
