What this site is
KakuroOnline.com generates unlimited cross-sums puzzles in your browser, at four difficulty levels, all free. Around the game we keep the references that actually help: the combination tables, a clear rules guide, real solving techniques, and printable puzzles for screen-free solving.
Built to be honest
Every puzzle is generated and checked for solvability, and the game accepts any grid that satisfies all the clues as a correct solution. There are no fake difficulty labels and no puzzles that need guessing. The combination reference is computed from first principles, not copied.
How it works
The generator and solver run entirely in your browser, so your solving never leaves your device and there is nothing to install. The site is deliberately light and fast and works on any screen size. It is published by Digital Signet.
