One of the most loved aspects of Minecraft is the beautiful world generation. Almost every seed creates a beautiful world for players to build and explore. Unfortunately, just as there are many beautiful seeds, some are just plain awful. These are the worst Minecraft seeds that have been discovered so far. -8797864507945267686 Screengrab via Minecraft This is a good world if you like a serious challenge and building underwater. You spawn in the middle of a large ocean with a small sand strip as the only land nearby. There are a few tiny desert islands spotted around the spawn point and a small glacier area. Be careful to avoid the Ocean Monument right next to the spawn, or the guardians will give you a nasty surprise. -1595926131 Screengrab via Minecraft This seed drops you onto a small island surrounded by other tiny islands in the middle of a large ocean. There aren't any trees near spawn, and it is difficult to find diamonds and other valuable materials early on. You will need to swim for a good while before you can find the basic necessities. 619717398 Screengrab via Minecraft This is considered to be one of the hardest seeds in Minecraft. Like most others on this list, you spawn out in the middle of the ocean surrounded by a handful of islands. Most survival islands are difficult, to begin with, but this one takes the cake. There is no wood within 1000 blocks of spawn. The initial island has a flooded cave with no ores that you can use. There is a small shipwreck within 150 blocks of spawn that you can use as a small wood source. The problem is that you will have to compete with the drowned and your own air supply to get it. Your best bet for getting started is hoping that the chest in the shipwreck or in one of the nearby ocean ruins has a useful item. 1256894139 Screengrab via Minecraft This seed isn't so much challenging as it is just plain broken. You spawn in a small plains biome with plenty of wood, but the surrounding biomes are either barren deserts or filled with coarse dirt. The regions surrounding the initial spawn are shattered. There are huge randomly generated spires and floating islands that break up the biomes and leave the world difficult to traverse. There is a small village about 1000 blocks away from spawn, but you will have to do a fair bit of pillaring to get to any buildings. -1228262971672933954 This is a difficult seed that can be a lot of fun too. You spawn on a grass block in the middle of the ocean. There are only desert islands immediately around spawn. You would have to go several hundred blocks before you find an inhabitable island. Within 1000 blocks of the spawn are some ocean ruins and an island covered in flowers. There is also an underwater nether portal. This seed is a nightmare if you are playing survival but can be a lot of fun if you want a good challenge or just like swimming. Just be careful of all the drowned and magma blocks around.
