Sams One-Block

Sam’s One Block is a simple survival datapack for Minecraft Java 26.3. You start on a single floating grass block in an empty sky. Each time you break it, a new block appears in its place. Collect materials, build a platform, and slowly turn your tiny starting point into a home.

As you break more blocks, you unlock different phases with new resources. These include wood, stone, ores, Nether materials, and End blocks. You also receive supplies at certain milestones to help you grow crops, raise animals, and keep expanding your island.

You can play alone or with friends. In multiplayer, everyone shares the same island and progress, so you can work together to gather resources and build something bigger.

The island exists in its own void dimension, keeping it separate from your normal world. No extra mods or resource packs are required. Just install the datapack and use /trigger ob_join to get started.

The goal is simple: survive, build, and see how much you can create from one block. After completing the main phases, you can continue collecting resources and expanding for as long as you like.
