Test your logic and arithmetic daily with 6x6 KenKen®! Try 4x4 KenKen® here.
The objective of a KenKen is to fill each row and column with exactly one of each possible number—in this case, numbers 1 through 6. You are not allowed to repeat any number in the same row or column. Each inner shape (marked by the boundaries) has an associated number and an operation. The result of applying the operation to the digits within that shape must equal the associated number—for instance, if a shape has a target number of 1 and the operation minus, you must be able to subtract one number in the shape from the other to get 1. Click the menu at top left and select “How to play” for more.
