Since b1.3, that added the ability of choosing seeds, many seed challenges appeared, such as 404, Chuck Norris and Iron man.
If you find cool/challenging seeds, or just make up challenges (such as wooden tools only, no torches etc), list 'em here.
Make a post/reply with the seed, if you have one, the challenge and the rules, if you have one, of course, and the version. (seeds from b1.3 and b1.7.3 are the same).

Here are a few challenges (I said challenges quite a few times ) to get inspiration from.
Have fun and good luck!

I gave myself a head start and I found these:
I tried seed "Good Luck" (case sensitive). Cool mountain next to spawn.
Also seed " " (just a space) it's very cool. No spoilers for this one.

I don't have one of my own, but thank you for sharing these, they were interesting to read. I had only heard of 404 and Survival Island challenges before. I might try one of these out!

You're welcome! Have fun playing these challenges!

The 404 challenge is such a classic! I can't believe i've never tried it... might have to make a world for it at some point!
