About CutePig Sudoku
CutePig Sudoku is an independently developed and maintained free Sudoku website. We help beginners understand their first deduction and give experienced players a place to practise advanced techniques. No account is required to play.
Analysis
Our explanations show candidate eliminations, techniques and reasoning chains so that you can follow each deduction. They provide a reference path, not a guarantee of the shortest or simplest possible solution. Puzzle scores are not official competition ratings.
Privacy & complaints
Imported images, entries and notes are not automatically uploaded to this website. Progress is saved on your current device; clearing site data may remove it. Share or export any puzzles you want to keep first.
