Kakuro Unlimited

Endless kakuro puzzles

• Easy: a 6×6 grid, counting the clue row and column. Short runs with friendly totals. Combinations and crossing runs are all you need.
• Medium: 8×8. You'll start spotting digits that a run must contain and finding the one cell where they can go.
• Hard: 10×10. Some runs only open up once you rule out combinations that can't fit their cells.
• Expert: 12×12. Lots of runs to juggle. Work from the corners and short runs inward.

Each puzzle has its own link, so you can send the exact grid to a friend and compare times.

1. Write a digit from 1 to 9 in every white cell.
2. Each clue is the total of the run of white cells next to it. The number above the diagonal is for the run going across to its right. The number below the diagonal is for the run going down.
3. A digit can't appear twice in the same run. It can repeat elsewhere in the row or column, as long as a black cell separates the two.

Tap a white cell to select it, then type a digit or use the pad under the grid. The runs through that cell light up, and their clues turn yellow. Turn on Notes to pencil in small candidate digits. A clue turns red when its run has a repeated digit, goes over the total, or is full but adds up wrong.
