Welcome to SuJoku.com
SuDoku is the latest puzzle craze that has taken the world by storm. Solving SuDoku puzzles is easier than it looks - all but the most difficult puzzles can be solved using only a few techniques. You don't need to know math - it's done by logic. Solve Classic puzzles so that every row, column and 3x3 box contains the numbers 1-9.
All puzzles in this website are original and hand-crafted by Joe Defries, 2-time Guinness™ World Record Holder, and author of the “World's Longest SuDoku Puzzle.” Each puzzle has a single synchronized solution.
Looking for something unique? Music, Symbol, Arabic, Chinese, Greek, Hebrew, Roman, Chess, Olympic, Astrology and Clock puzzles based on unique symbols & characters to emphasize the use of logic. Quad (or Hyper) SuDoku puzzles solve exactly the same as regular SuDoku puzzles PLUS there are 4 (Quad!) extra regions which each also contain the numbers 1-9. Our Trivia/Word puzzles use 9 alphanumeric characters, concealing a hidden word along a row, column or diagonal.
