Welcome to KENKEN! You may want to cancel your appointments, lock the doors, pull down the shades, and turn off your phone. Because you'll soon discover that KENKEN is very addictive! It's a grid-based numerical puzzle that uses the basic math operations — addition, subtraction, multiplication, and division. Don't worry, you definitely don't need to be a math wiz to enjoy these puzzles! Just as important are your logic and problem-solving skills. You can even think of KENKEN like a game of pool or chess: The more you think ahead to your upcoming moves and consider all the possible outcomes, the better you'll get!KENKEN was developed in 2004 by ... no, not two guys named Ken ... Japanese teacher and puzzlemaster Tetsuya Miyamoto. "Ken" translates to "wisdom" in Japanese, so KENKEN means "wisdom squared." True to its name, the puzzle can actually make you smarter the more you play.
