How to Track and Unlock All 17 Progression Levels

One Block Map organizes your survival run into themed progression levels. As you break more blocks at the central generator, the map automatically shifts through standard overworld biomes, underground structures, and dimensions.

Checking Your Current Level

Open your in-game chat screen while standing on your island to view the level progression list. This display shows the unique themed phases available in the challenge so you know what blocks and mobs to expect next.

Full Progression Level Order

To unlock new structures, biomes, and mobs, keep mining the central block to advance through the following stages in order:

1. Early Overworld & Caves: Plains, Underground, and Deep Cave.

2. Surface Biomes: Snowy & Wilderness, Desert, Jungle, Barren Lands, Ocean, Pale Garden, and Swamp & Cherry.

3. Structures & Dimensions: Mansion, Nether, Trail Ruins, Ancient City, and Stronghold.

4. Endgame: Infinite.

Each new phase introduces the blocks and hazards of that environment. For example, once you reach the Ancient City / Deep Dark level, you must be prepared to face the Warden spawning on your island. Reaching the Stronghold level gives you the pieces needed for late-game survival before the generator enters the final Infinite phase, where you can keep mining indefinitely.
