It's only hard unless you haven't learned strategies to solve them, and haven't practiced them.
Unfortunately, there aren't many ways to learn it beyond the simplest level, so I've put some free vids up at http://mathmojo.com/kenken
They help you learn how to solve some of the hardest KenKen puzzles there are.

There are many maths puzzles that have not been solved. Any puzzle that has an answer cannot be harder than one that mathematicians still have not solved. So a second hardest puzzle cannot exist. Even amongst puzzles with answers, what you may consider hard may be easy to someone else, and conversely.
The puzzle known as "Al Escargot" (the snail) is currently considered the hardest Sudoku puzzle. It was created by a Finnish mathematician called Arto Inkala. One of the hardest Sudoku books available is "Extreme Sudoku" by Antoine Alary, not to be confused with "X-TREME Sudoku" by Nikoli & Co. or "Sudoku Xtreme" by Christopher Monckton, which are both an order of magnitude easier.
