A 4×4 version of the popular KenKen game. The answers only consist of the numbers 1 to 4. No digits can be repeated in any row or column. Solve each cage (outlined group of boxes) so that the digits equal the target number using the math operator supplied. For example a cage with two cells that has the equation “1-” can be solved by either: 4, 3; 3, 4; 3, 2; or 2, 3.
