About killersudoku.co

killersudoku.co is a free site for playing killer sudoku and other kinds of sudoku in your browser: a new daily killer sudoku, an archive, classic sudoku, kakuro, samurai, jigsaw, X and mini sudoku.

The site is built to be calm and clear. The puzzle is the main thing on the page, it works with a touch screen or a keyboard, and there is nothing to install or sign up for.

All puzzles were generated for this site by our own program. Each one was checked by a solver, which confirmed that it has exactly one solution. The puzzles, the design and the icons were made for this site.

The site is made and run by Takreparation Skåne AB, a small company in Ängelholm, Sweden. See the contact page for company details.
