Get startedWhat is KenKen?
KenKen is an arithmetic-based logic puzzle invented by Japanese math teacher Tetsuya Miyamoto. Players fill a grid with numbers so that each row and column contains each number exactly once (like Sudoku), but cells are grouped into "cages" with a target number and math operation that the cage's numbers must satisfy.
