Kakuro Solver builds no-repeat sums
Every across and down clue becomes ordered candidate placements using digits 1 through 9, with no repeated digit inside that clue's run.

Solve Kakuro number crosswords with sum combinations.
Enter the Kakuro grid manually with black clue cells, empty cells, across sums, and down sums. The Kakuro Solver enumerates 1-9 no-repeat combinations, propagates constraints, and searches locally in your browser.

Kakuro Solver workflow from clues to answer
Kakuro Solver search intent is separate from Sudoku because Kakuro is a number crossword built from across and down sums, not 3×3 box rules.
Kakuro Solver manual grid input
Type the black cells and blank cells, then add across and down sums from their clue cells. The Kakuro Solver stays manual and predictable, with no camera or OCR workflow.
Kakuro Solver combination pruning
For each clue, the solver enumerates 1-9 no-repeat combinations, removes digits that cannot fit crossing runs, and shows which numbers were excluded.
Kakuro Solver answer diagnostics
The result area shows the completed grid, clue candidate combinations, excluded digits, conflict positions, no-solution messages, uniqueness, and the reasoning trail.
How the Kakuro Solver works
This Kakuro Solver uses browser-side combination enumeration, constraint propagation, and backtracking for manually entered number crossword clues.
Kakuro Solver intersects crossing clues
Each empty cell belongs to one across clue and one down clue. The solver repeatedly intersects those candidate sets until no more digits can be removed.
Kakuro Solver checks uniqueness
When propagation alone is not enough, the solver backtracks through the smallest remaining candidate set and stops after proving no solution, one solution, or a second solution.
Kakuro Solver input guide
Use these Kakuro Solver tips to transcribe black cells and clues accurately before solving.
01
Mark every Kakuro Solver cell type
Use # for every black or clue cell and . for every answer cell. Keep each row the same width so clue positions such as R2C1 point to the intended cell.
- Spaces are optional in the layout
- Rows must all have the same number of cells
02
Enter Kakuro Solver across and down sums
Write one clue per line from the black clue cell. Across fills blanks to the right; down fills blanks below. A line like R3C1 A 17 means the answer cells to the right must sum to 17 without repeats.
- A/across and D/down are both accepted
- Each empty cell needs one across clue and one down clue
03
Know the Kakuro Solver boundaries
This page does not recognize Kakuro photos, scans, screenshots, or camera input. It only solves the cells and clue sums you manually type, entirely in front-end JavaScript.
Manual input keeps the Kakuro Solver private, fast, and separate from ordinary Sudoku Solver behavior.
Kakuro Solver FAQ
Common questions about using this Kakuro Solver for number crossword puzzles.
Is this Kakuro Solver the same as a Sudoku Solver?
No. Kakuro is a number crossword: each clue is an across or down sum, and digits 1-9 cannot repeat inside that clue's run. A Sudoku Solver focuses on 9×9 rows, columns, and 3×3 boxes, so Kakuro has its own separate page and search intent.
How do I enter a puzzle into the Kakuro Solver?
Type the grid with # for black or clue cells and . for empty cells, then add one clue per line. For example, R2C1 A 16 means the black cell at row 2, column 1 gives an across sum of 16 for the blank run to its right.
What does the Kakuro Solver show after solving?
The result area shows the complete answer, candidate combinations for every clue, excluded digits, conflict positions, no-solution warnings, whether the puzzle is unique, and optional step-by-step reasoning.
Does the Kakuro Solver use the 1-9 no-repeat rule?
Yes. Every across and down clue is solved using digits 1 through 9, and a digit cannot repeat within the same clue run. Crossing clues must agree on the value of the shared cell.
Can the Kakuro Solver detect no solution or multiple solutions?
Yes. If clues contradict each other, the Kakuro Solver reports no solution and highlights known conflict positions when possible. If it finds a second valid answer, it warns that the puzzle is not unique.
Does the Kakuro Solver support OCR, photo recognition, or screenshots?
No. This tool does not do image recognition, photo recognition, camera capture, OCR, screenshot parsing, or automatic puzzle extraction. It only solves manually entered grids and clues.
Are my Kakuro Solver inputs uploaded?
No. After the page loads, the Kakuro Solver runs in browser JavaScript. Your grid, clue sums, candidates, and solution search stay on your device.
