i got a sudoka game for my pc and on the hardest level i have yet to find a puzzle that took me more than 33mins 46 seconds
i was going to say 30 minutes but that would be lying as one took me longer

If your finding all soduku puzzles a cinch, try formulating an algorithm that would be guaranteed to be able to solve them in a formulated fashion (i.e. without just doing infinite trial and error - brute force search not allowed) - then you wil; truly be crowned as a sudoku grand maste, glasshopperr! (with your maths background i reckon you could do this...)
PM'ing my answer to the logic puzzle..... half an hour, and one sheet of paper with a lot of scribble on it here.... nice one TightEnd
