Who invented the KenKen puzzle?

KenKen was developed in 2004 by acclaimed Japanese mathematics instructor Tetsuya Miyamoto. (No, it wasn't developed by two guys named Ken.) His goal was to improve his students’ math and logic skills, and what better tool to use than a puzzle? He designed KenKen to be understandable, fun, and challenging for students of all abilities. Most importantly, he wanted the puzzle to encourage independent thinking, emphasize logic and reasoning, concentration, and perseverance. Ultimately, Mr. Miyamoto’s educational tool became a worldwide sensation for both kids AND adults.  KenKen is now offered as a daily feature in over 150 newspapers worldwide (including the New York Times) and is used in the classroom by over 30,000 teachers.
