In summary, the conversation was about the game Sudoku and the different methods and websites people use to solve it. The speaker has become fond of the game and averages 12 minutes on hard puzzles. They also mention getting their mom and a physics major hooked on the game. However, the speaker does not find the puzzles in newspapers to be challenging enough and prefers to play on a website. They also mention a computer assignment they had to do involving creating a solver for the game.

I've become particulary fond of these, 3x3 boxes with 3x3 boxes in each and you must have 1-9 vertical, horizontal and in each 3x3 box. I'm sure most have seen it before. The link below provides a program for it. I average 12 minutes on hard puzzles.

I did too but it takes her like an hour to finish one in the news paper... Sad.

I have been playing it for a while now. I think the newspapers are a bit too easy: Yesterday the paper had a "5 star" (out of 5) puzzle and it took less than 10 minutes. I play at www.websudoku.com

All the physics majors i talk to can do these things in like 10 minutes max. This one girl in this class i took... she's all "I love these soduku thingies, it only takes me an hour to finish them sometimes".

I then proceeded to slap her

It depends on how much attention I am paying to it and how much I am playing. I have no idea how long the ones in the newspaper would take me. I have only done like 2 from there.

Our first computer assignement was making a brute-force solver for these (we weren't ALLOWED to make a 'smart' solver, because there were so many around the net)
