Minecraft challenge
One Line
The Overworld is only one block wide. Follow the line, gather supplies and find twelve End Portal Frames to build your own portal.
- Java & Bedrock
- Private server
- No extra mods
A narrow route
Every step has two edges
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.

Tips for One Line
The line exposes much of the world at once. Use its visible sides while searching.
- 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.
