What is fastest way to solve a sudoku puzzle?

Question

in a contest, what is the easier and faster technique to bit your opponents in solving sudoku puzzle. please help me.

Answer 1

The way I do it is work the first 3 columns first, like if 2 blocks have a 1 in them, then I look to the third block and see if it can be easily placed, then 2 etc., up to nine, then move to the middle and do the same, then the last 3 in the column, then you can do accross ways too and you will find that you have put loads of numbers in so you can then start at the beginning again or if there is only 2 numbers missing from the line up or accross see it you can fill in that missing number, some are hard and some are easy, I love the ones with the letters in it to 0 to 9 and A to F, great fun, hope this helps you, goodluck! :)
