Sudoko, Are You In?

I admit I am hooked, it all happened one weekend while visiting my husband's family, they printed a dozen Sudokos downloaded from a website and we spent the entire day solving puzzles. The popularity has become an inspiration for cause related organizations, none more so than Fairtrade at work who nicely tapped a trend with a Sudoko-esque game, try it, I'm sure you'll like it... http://www.fairtradeatwork.org.uk/#.
