KenKen Math Puzzles
KENKEN was developed in 2004 by the Japanese mathematics instructor Tetsuya Miyamoto. His goal was to improve his students’ math and logic skills. Most importantly, he wanted the puzzle to encourage independent thinking, emphasizing trial and error, concentration, and perseverance. Simply put, the game is a grid-based numerical puzzle that uses the basic math operations - addition, subtraction, multiplication, and division - while also challenging your logic and problem-solving skills.
