KenKen can be a great way to challenge your puzzle-solving skills and pass the time.

Step 1: Examine the puzzle
Examine the KenKen puzzle. The puzzle is composed of a grid of squares, with an equal number of columns to rows, and puzzles come in different sizes.

Step 2: Understand the rules
Understand that the goal of KenKen is to fill the puzzle with digits so that no number repeats in any row or column. Digits are determined by the puzzle size, so a four by four-inch puzzle will use the digits one through four.

Step 3: Identify the cages
Identify the cages, the heavily outlined boxes inside the puzzle.

Step 4: Start with single cages
Fill in any cages that have only one square. The number in the upper corner is the only number that can go there.

Step 5: Fill in multiple cages
Fill in the remaining cages by following the mathematical operation indicated in the top corner of the cage to produce the number indicated.

Tip
The order in which digits in a cage are subtracted or divided does not matter.

Step 6: Look for specific combinations
Identify cages where only one combination of numbers will work, and fill that combination in.

Tip
Digits can be repeated in a cage as long as they do not repeat in a row or column.

Step 7: Experiment
Experiment with different numbers in the squares you're unsure of, using your eraser when needed.
