HOW TO PLAY
How to play Sumline
Solve three original Kakuro puzzles. Fill each white cell with a digit from 1 to 9 so every across and down run adds up to its starting clue; digits cannot repeat within a run.
Controls
- Click a cell and enter a digit with the number keys or on-screen keypad; undo, check, or restart
- R or the on-screen button: restart
Tips
- Begin with short runs whose sums are very small or large; they usually have fewer possible combinations.
- Rules and control tips are shown in the game.
