## More KenKen Puzzles

Examples of 6x6 and 7x7 KenKen puzzles.

The standard 4x4 KenKen puzzle is pretty easy -- most people can
do the puzzle in a few minutes.
But larger KenKen puzzles are more involved and they require more
steps (and more mathematical reasoning) to solve correctly.

- 18x (in a straight line) must contain 1-3-6
- 18x (in an L shaped cage) must contain either 1-3-6 or 3-2-3

### Example of a 7x7 KenKen puzzle

A 7x7 KenKen puzzle is a bit more work than a 6x6, but most of the
solving techniques are similar.
You can add pencil notes for some of the two square cages until you have
solved some of the squares.
