What strategy tips will help me solve Killer Sudoku puzzles?

You will need to use all the strategies that you use to solve sudoku, plus some others too.

The main extra technique needed is to look through all the boxes and look at the sums. Then work out what possible numbers can be placed in each box in each region.

This usually helps you to get started with the puzzle with regard putting in some values.

Another technique you can use which is different to sudoku is called the rule of 45.
