About One Block Challenge
From ModrinthA Minecraft modpack centered around the One Block challenge, where players begin on a single block that regenerates infinitely. Progress through unique phases, gather resources, explore dimensions, and build your world from almost nothing.
One Block is a fun survival modpack where you start on a single block floating in the void. Breaking the block gives you different items, blocks, and mobs as you progress through phases. Build your island, gather resources, and survive using just one block.
