This seed spawns you in a taiga with a village nearby. On the opposite side of the village where you spawned, you can find a ravine with an abandoned mineshaft. In the mineshaft, there are a dungeon and a chest minecart with a diamond. This seed seems to just keep getting better the deeper you go.
This seed spawns you facing a set of snow-capped extreme hills surrounded by swamp. Not only does this area have a unique swampland M biome portion, it also has a dungeon lying beneath the surface. Then, if you’re willing to travel, there’s a couple more extras on this seed too.
It’s not very often that you can get a diamond immediately after you spawn. In this seed not only can you start with a diamond, but you can also get other useful ores like gold and iron.
This seed seems pretty normal when you spawn in a patch of plains surrounded by forests and a small extreme hills biome. However, once you start traveling west, you will begin to see the village where the diamond lies.
This seed spawns you in a zombie village. Thankfully it spawns you during the day, so any zombie villagers that come toward you will burn up, but I’d still wait for them to die off before exploring the village further.
Aside from having zombies everywhere, zombie villages are easy to distinguish due to the lack of doors and torches around the village.
This seed has three structures fairly close together. There’s a dungeon containing gold items, a desert temple that holds two diamonds, and a savanna village with iron items. All three of these structures leave you with plenty of great items to start your survival.
