Kakuro Solver
Build a bounded Kakuro grid and solve its intersecting cross-sum constraints entirely in your browser.
For each cell choose Block, White, or Clue. Clue cells accept an across sum (→) and/or down sum (↓). Optional known white-cell digits must be 1–9.

Solver method and bounds
Grid size is 3×3 through 10×10. Every white cell must belong to one across and one down run. Runs contain 2–9 nonrepeating digits and must match their clues. The solver builds valid run permutations, propagates intersections, and uses deterministic bounded backtracking. It checks up to two solutions and does not claim uniqueness unless exactly one is found.
