A narrow route

The Overworld is one block wide

The generated Overworld follows a single line. Biomes, plants, trees and small ore patches change along it. Oaks, berries, coal and iron near spawn help you begin. The Nether and End remain ordinary worlds.

Isolated water and lava sources and chests lie beneath the surface. Each chest contains one End Portal Frame. Collect twelve, build an inward-facing ring and craft the Eyes of Ender yourself.

Player builds and flowing liquids can extend beyond the generated line.

Example round: after traveling several sections, you spot a chest just below the edge. Mine the block above it, secure the frame and decide whether to continue or gather food first.

Long landscape strip only one block wide, with trees and ores exposed in its rocky side.
Trees grow along the narrow line; ores show in the exposed rock below.

Along the line

Tips for One Line

Look below the edges too. You can spot chests there.

01Check the edges
Chests sit just below the surface and can be spotted from the side.
02Mark water and lava
Isolated sources sit in the rock. Remember their locations for farms and Nether portal plans.
03Place the portal carefully
Set the twelve frames while standing inside the 3 × 3 opening; further chests offer replacements after mistakes.

Another twist

Combine One Line

An extra rule changes your journey along the narrow route.

One Line + Biome = Effect
Each new biome section may bring a different effect. Check the display before pressing on.

One Line FAQ

The key rules of the one-block-wide world.

Can I widen the line?

Yes. The Overworld generates only one block wide. You can place your own blocks beside it and let fluids flow beyond it.

Is there a ready-made End portal?

No. Chests contain individual frames. Build a ring from twelve frames and craft your own Eyes of Ender.

Are the Nether and End one block wide too?

No. Only the Overworld uses line generation. The Nether and End remain normal.
