Welcome Dale B.
The answer is yes.
You don't indicate what level of puzzle you solve or what 'techniques' you know, but I would check out these two websites
www.angusj.comwww.simes.clara.co.uk/programs/sudoku.htmfor info about Sudoku, plus you can learn a lot by browsing through these forums. There is also a link on the Sudoku.com homepage called 'how to solve' that contains info. Good luck.
