Acclaimed Japanese mathematics instructor Tetsuya Miyamoto developed KenKen in 2004 with the goal of improving his students' math and logic skills. This understandable, fun, and challenging puzzle quickly became a favorite leisure activity for all ages throughout Japan and then for millions of players worldwide. In 2008, Nextoy LLC brought KenKen to the United States, and it soon was the first daily feature since the crossword puzzle to appear in theNew York Times. Now it's carried in theLos Angeles Times,Chicago Tribune,The Times of London, Scholastic classroom magazines, and more than 100 other national US publications.

First Japan gave us Sudoku—and then KenKen®, an addictive grid-based numerical puzzle that uses basic math operations (addition, subtraction, multiplication, and division) while challenging your logic and problem-solving skills. As with a game of chess, solvers have to think ahead and consider all the possible outcomes before making a move.

Wherever you are, whenever you're solving, when you do KenKen®, you're giving yourself a brain-boosting workout!
