What Is the “Minecraft 100 Days One Block” Challenge?

The Minecraft 100 Days One Block challenge is a self‑imposed survival run where players start on a single stone block and must survive for 100 in‑game days without ever leaving the area surrounding that block. All resources must be generated from the block itself or from items dropped by mobs that spawn nearby. The goal is to experience a compact, resource‑management focused playthrough while showcasing creativity and planning.

Preparing for Day One

Before you even break the first block, a few preparations can make the difference between early defeat and a successful marathon. Follow these steps:

Day‑by‑Day Progression Overview

While the challenge lasts 100 days, most players break it into three phases: early, mid, and late. Below is a concise roadmap of what to aim for in each phase.

  1. Early Phase (Days 1‑20)
    • Harvest the initial block to obtain the first set of cobblestone or dirt.
    • Craft a crafting table, wooden pickaxe, and basic tools.
    • Establish a simple shelter using the block’s drops to protect against night‑time mobs.
    • Begin farming any seeds that may drop, such as wheat or carrots, to secure a food source.
  2. Mid Phase (Days 21‑60)
    • Upgrade tools to stone, then iron, using the increasingly larger stacks of material you collect.
    • Construct a compact furnace system for smelting ores that appear in the drop pool.
    • Set up a basic mob‑spawning chamber to increase the rate of valuable drops like iron ingots and gunpowder.
    • Start a small garden of saplings and seeds to ensure a renewable food supply.
  3. Late Phase (Days 61‑100)
    • Focus on end‑game items such as enchanting tables, bookshelves, and eventually a portal frame if the rules allow it.
    • Maintain a steady flow of resources by expanding the mob‑spawning area while keeping it within the one‑block radius.
    • Use the final days to polish the base, create decorative builds, and record the achievement.
