In addition the puzzle involves maths and sometimes quite complicated solving rules - so you'll need to have your wits about you to solve quite a few different killer sudoku puzzles. The Rules of the GameThe rules are as follows for 9x9 puzzles, which is the most commonly seen size for this puzzle as with sudoku. Of course with other sized puzzles these are simply to be replaced with the relevant dimensions, so for a 6x6 puzzle use 1 - 6 and 3x2 boxes (or indeed 2x3 depending on their shape):
