Seed: Ansem Seeker of Darkness (Captialize A, S & D)
I <3 you guys, I only put a form up so you can submit stuff yesterday and already I've gotten some awesome submissions like this! This was sent in by Tariq458, all credit goes to him/her 🙂 I'm just going to quote what they said about it, as I couldn't have said it better myself:
I tried ‘Ansem Seeker of Darkness’ and got a seed with a massive cave system near spawn that went deep enough for me to find diamonds. I haven’t completely explored the cave–it’s HUGE–but inside so far I found exposed redstone, lapis (lots), gold, diamonds and a couple dungeons. I even found obsidian! Be careful though, the cave has many lava pools and falls. The dungeons have saddles in them too, so this is a great seed to use grab all the achievements quick!
Besides the cave, the seed is interesting to explore, a few floating islands, snowy deserts, lots and lots and lots of caves, some flat land for building, some islands. I found a dungeon close to where I spawned that opened up into the massive cave. Hope this helps someone!
Seed: George Carlin (Capital G & C)
In my opinion this is the perfect seed. It’s the one I’m using for my actual world I’ll be playing with my friends, and they all like it too. That waterfall there is natural too 🙂
So you’re up for a challenge? Well I really hope you are, because what lies ahead is one of the most treacherous naturally generated minecraft seeds of all time. Known as the “404 challenge” this seed became well known because of the huge cave you enter by falling down along with a ton of Gravel. unfortunately the rest of the world is not very interesting.
You will spawn in an area hopefully near a large body of water. Make your way to a large patch of gravel that looks like the picture below. Prepare yourself (you have until nightfall to gather your required materials), and then dig the gravel to descend.
Seed: gargamel (all lowercase)
This seed is simply amazing; it’s pretty much a sealed grand canyon (extremely tall and hard to get out of) with only 2 exits from what I can tell. I only had a look around for 5 minutes, but everywhere you look is filled with awesome caves and dungeons.
Oh also you spawn underground in a cave in complete darkness, good luck!
P.S. There is an underwater dungeon near spawn 🙂
