How Kakuro works
If you can add up to 9, you can play Kakuro. Three rules are the whole game.
Fill the white cells
Every white cell takes a digit from 1 to 9.
Match the clue
Each run adds up to the number in the black cell at its start: the top-right number clues the run to the right, the bottom-left number clues the run going down.
No repeats in a run
A digit can appear only once within a single run, though it can repeat elsewhere in the grid.

What is Kakuro?+
Kakuro, also called cross sums, is a number logic puzzle. You fill the white cells with digits 1 to 9 so that each horizontal and vertical run adds up to the clue printed in the black cell at its start. The catch: no digit can repeat within a single run.
Is Kakuro like Sudoku?+
They share the no-repeats idea, but Kakuro is about addition rather than placement. Instead of completing rows and boxes with one of each digit, you make each run sum to a target using distinct digits. Many solvers find Kakuro more varied because run lengths and sums change every puzzle.
How do I get better at Kakuro?+
Start with runs that have only one possible combination, such as a two-cell run summing to 3 (only 1 and 2) or 17 (only 8 and 9). Use those locked digits to constrain crossing runs. Our combination reference and strategy guide walk through the technique in detail.
