Kakuro Generator

Creates classic kakuro puzzles: a crossword-like grid where each run of white cells must add up to the sum clue printed in the black cell before it, using the digits 1-9 without repeats inside a run. Every generated puzzle is verified with a solver to have exactly one solution. Solve it on the page with checking and hints, print a clean sheet with or without the solution, export PNG/SVG or publish an interactive embed.

Runs 100% in your browser — your puzzles never leave your device.

Notes

  • Rules: fill every white cell with a digit from 1 to 9 so each across and down run adds up to its clue; a digit may not repeat within a single run.
  • Every puzzle is checked with a backtracking solver and is only shown once it has exactly one solution.
  • Difficulty changes the grid pattern: easy grids use short runs of 2-4 cells, hard grids allow long runs up to 7 cells, which admit far more sum combinations.
  • Runs 100% in your browser — your words and puzzles never leave your device unless you publish an embed.
