Since puzzles are having a vogue, muirhead's in particular pretty much ground all postgraduate research in the maths department to a halt for a day, i thought i'd show you to a source of good puzzles which took it out for a week:
MUMS puzzle hunt

some of these puzzles are off the hook brilliant. I want to give you an example but i don't want to spoil them.
+ Show Spoiler +

here's puzzle 1.1 Apollo 13.

you're given some text that's like the chatter you get on space missions. You notice that they use a lot of words that are in the phonetic alphabet (words like alpha, beta, charlie, delta, echo, foxtrot,... sorry i was trying to remember how many i knew)

you pick out all these words and write the corresponding letter, this spells something like (my pdf viewer is broke so i can't say exactly)

EXRATDIDAUSEWABUN

split this up into words to get EXRAT DIDA USE WABUN.
Now what's dida and wabun? it turns out wabun is a type of japanese morse code, a way to talk in dots and dashes. It also turns out one of our team has a pilots license and he tells us that di and da are the way you communicate dots and dashes over the radio.

So we go through the text picking out all the di's and da's and translate it using a wabun -> phonetic japanese dictionary (as can be found on all good wiki's) and get the word moonrise.


The website have full solutions to all of them. They're pretty odd, some of them you'll need to google stuff, others are pretty much self contained. I doubt anyone will have to drive to do them now, not with the answers right there. We had a team of 8 or so working on them all day and didn't get all of them.

TL.net team next year?

You want to have fun with imba puzzles, Try this:

http://deathball.net/notpron/levelone.htm

I think it would be pretty cool if we can get a TL team to solve this and beat the hardest game on the internet . Ill make a thread in general when I feel free.

I solved it years ago. At some point you are going to have to pay to register an account to continue. Davidm also recently added a new level that requires Remote Viewing. Before that I would have recommended it, but I can't anymore. It's a shame really. =/

The oldest and largest scale puzzle competition that I know of MIT Mystery Hunt

http://web.mit.edu/puzzle/www/hunthistory.html

Just be warned, most puzzles aren't meant to be solved by 1 person. It's meant for a team of 40+ people spending one weekend (~60 hours). A couple cool technology-specific sample puzzles:

Sound Quality (Audio puzzle)
Ginormous (Math puzzle)
I Get Around (Video Game puzzle)


If you're just one person, then Microsoft College Puzzle Challenge is easier to look at, since it's meant for teams of 4 people, 12 hours, so the puzzles have fast solutions if you see them.
