Your goal is to fill up the 6×6 grid with numbers 1-6. Each column and row must have exactly one of each number, just like in sudoku. Each box (an area outlined with thick black lines) has a target number and a mathematical operation listed in the top-left corner. The numbers within the box must result in the target number when the mathematical operation is employed. For example, a box with 3+ could be satisfied with 1 and 2, as 1+2=3. Similarly, a box with 2÷ could be satisfied with (1,2), (2,4), or (3,6) as 2÷1=2, 4÷2=2, and 6÷3=2. For an example puzzle, visit our KenKen guide.
