I had to travel interstate the other day without my PC and so I thought to keep me amused I'd grab a Sudoku app for my K-Jam. I assumed I'd try it out for a few minutes and then happily throw it away still convinced that sudoku wasn't for me.
Well, the folks at Ludimate have a great implementation they called Sensible Sudoku which not only got me over the hype but had me buying a licence within an hour!
I think I'm hooked! But I'm sure my brain is getting a great workout
