What One Block Challenge works with.
| Platform | Java Edition |
|---|---|
| Loaders | Fabric |
| Minecraft versions | 1.21.10 |
| Environment | Client, Server |
One Block Challenge is a one block challenge modpack for Minecraft Java on Fabric. You start on a single block floating in the void, and it regenerates every time you break it. The pack is built for survival play, and it must be installed on both client and server.
Loaders and versions
- Fabric: Minecraft 1.21.10.
How the challenge plays
Breaking the block hands you different items, blocks and mobs as you move through phases. You gather resources, build out your island, explore other dimensions and grow a world from almost nothing. Modrinth tags the pack as lightweight and optimization alongside adventure, challenging and combat, so the focus is on survival progression rather than a heavy kitchen-sink mod list.
- Start point: one block in an empty void.
- Loop: break the block, collect what it gives, expand your island.
- Progression: unique phases that change what the block produces.
- Goal: reach other dimensions and build a world from scratch.
How to install One Block Challenge
The pack is a Modrinth modpack, so it installs through a launcher that reads Modrinth packs. Our guide to installing a modpack from CurseForge or Modrinth covers the launcher side in detail.
- 1.Open the Modrinth App, or Prism Launcher or another launcher that reads .mrpack files.
- 2.Add One Block Challenge from Modrinth. The launcher downloads the listed mods and the right Fabric loader.
- 3.Launch the new profile and create a world.
What to expect
The appeal is focus. One mechanic drives the whole run, and the phases supply the variety. The trade-off is narrow scope. This is a challenge pack with a fixed premise, not an open-ended world, and it links no public source code, so there is no repository to check for changes or report issues.
Questions about One Block Challenge.
3 questions
How do I install One Block Challenge?
Use the Modrinth App, Prism Launcher or another launcher that imports Modrinth packs. Add the pack from Modrinth and the launcher downloads the listed mods and the Fabric loader for you. Then launch the profile and create a world. No extra dependencies are listed for the newest release.
Which Minecraft version does One Block Challenge support?
The pack runs on Fabric for Minecraft 1.21.10. It is the only loader and version listed, so older or newer game releases are not covered. Check that your launcher profile uses 1.21.10 before you create a world.
Does One Block Challenge work on multiplayer?
The pack lists both client and server as required, so it is not a client-only pack. A server is part of the setup alongside the client.
