Could I have some help on solving this puzzles as I don't understand the advanced strategies that I need to solve this puzzle. I have tried using the rule of 45, definite sums and other basic techniques, but this is how far I can go, when explaining the advanced techniques, could the explanations be easy to understand please? As I don't understand them. All help will be appreciated.

It looks as if you have printed this from JSudoku.
If so use the "s" button to suggest a move.
Alternatively go to Jean-Christophe's site where he covers many techniques:
http://jcbonsai.free.fr/sudoku/
for further techniques go to the Assassin site:
rcbroughton.co.uk

This puzzle does not require any special techniques, just careful analysis of combinations and full use of the "45" rule, e.g. one move needed is Innies on N1&4.

I hope that this helps.
