Rules for playing KenKen:
- Fill in each box with a number - which numbers you use depends on the grid size. If the grid is 4x4, then you use the numbers 1-4. If the grid is 7x7, then you use the numbers 1-7.
- Do not repeat a number in any row or column.
- The numbers in each heavily outlined set of of squares, called cages, must combine (in any order) to produce the target number in the top corner, using the mathmatical operation indicated. For example: if the symbol at the top of a cage was 3- and you had a 6x6 grid, then possible numbers for that cage are 6-3, 5-2, or 4-1.
- Until you know what the numbers are, it helps to write down possible options in the bottom of the squares or in the margins.
