KenKen Puzzle LLC

KenKen was developed in 2004 by acclaimed Japanese mathematics educator Tetsuya Miyamoto (no, not two guys named Ken). His goal was to improve his students’ math and logic skills...and what better tool to use than a puzzle? So he developed one that would be understandable, fun, and challenging for anyone at any level. Most importantly, he wanted the puzzle to encourage independent thinking, emphasizing logic, reasoning, concentration, and perseverance. His puzzles immediately met with unbelievable success, escaped the classroom to become a favorite adult pastime, and became an international sensation. KenKen puzzles now appear in over 150 newspapers worldwide, and millions of puzzles are played every day by puzzle fanatics everywhere. Since its invention, KenKen has become the world's fastest growing (and most enjoyable) puzzle since sudoku, and has proven to be one of the world's best brain exercises.
