Minecraft OneBlock Servers
OneBlock is a challenging survival gamemode where you spawn on a single grass block floating in the sky. However, this isn't a regular block - it's a special infinite block that generates a new and sometimes different block in its place each time you break it. The infinite block can also spawn mobs, and sometimes generates chests with useful items inside.
As you continue breaking the infinite block, gameplay advances through different phases, with each phase unlocking new blocks and mobs. During the first phase the infinite block generates basic materials like wood and spawns farm mobs such as sheep and cows. The Underground phase introduces stone and ore blocks, and in the Nether phase the infinite block generates soul sand and netherrack and spawns Blazes and Ghasts.
Similar to Skyblock the goal is to carefully gather the resources you need, expand your island, build a base and survive. Most OneBlock servers also have quests, challenges and level progression for additional goals and rewards.
