KenDoku® is a brilliant new puzzle, brought to you by the same people who launched KenKen®.

KenDoku combines the features of KenKen with those of SuDoku, creating a perfect marriage of those magnificent number puzzles. KenDoku comes in two different grid sizes, 6x6 and 9x9, so everyone can choose the size that best matches the time they want to spend on a puzzle and their own solving skills. Within each grid size the puzzles come in a wide range of levels of difficulty – the easiest ones can be solved by bright children while the most difficult ones present a real challenge, even to experienced solvers. It is this combination of different grid sizes with a range of difficulty levels that makes KenDoku a great puzzle for everyone!

As with KenKen, one of the key features of KenDoku is the fun that can be had from using logic combined with the simple basic arithmetic skills: addition, subtraction, multiplication and division. This feature also works as a great way to enhance your arithmetic skills, so children (and adults) will be able to improve their ability at mental arithmetic almost subconsciously while they are enjoying the solving process. The two of us are puzzle enthusiasts who were addicted to SuDoku until we came across KenKen and now KenDoku, both of which have supplanted SuDoku in our affections. We are confident that you will share in our enthusiasm as you try KenDoku. This is a puzzle with a truly great future!
