Hello exited person! You are probably here because you think this is somewhere where you can download old 1.7.3 worlds rite? Well then you've come to the rite place! I have an old 1.7.3 .jar so I used it to get some old seeds. I will be adding more worlds soon and taking requests! The folder you download will contain some worlds, drag those out and put them in your saves folder. So far I have the following worlds!

404: You may have heard of the 404 challenge. With this old seed pack you will be able to play the original 404 challenge! Just dig in the near-by gravel and fall into the hole! Google 404 challenge for details.

Glacier: This world generates amazing cliffs and hills! You really need to try it! The biomes and generation may be a bit glitchy.

gargamel: This world will generate more amazing terrain, let the worlds beauty speak for its self! It may also be a little glitchy like Glacier.

That's all that I have for now! Please give me some suggestions as to what seed I should add next! If any of them are weird or glitchy, I may be uploading a better version soon! Please diamond if you liked!

Additional Notes

Worlds may be glitchy.
Glitchy: Wrong biomes, bad chunk generation, ect.
