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, Chinese, Greek, 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 Word puzzles use 9 alphanumeric characters, concealing a hidden word along a row, column or diagonal.
The World's First truly 3D SuDoku puzzle, created by Joe & featured in The World's Greatest Treasure Hunt. Book Launch in February 2010.
Warm greetings to all competitors that Joe met at the 2009 U.S. National Sudoku Championship, October 24th in Philadelphia, Pennsylvania.
Cheers to all fellow SuJokuholics!
