ONE BLOCK
The core loop from day one
Step
You start with exactly one block. Breaking it gives you your first resources, and those resources fund everything else. The cycle repeats: break blocks, collect materials, upgrade your tools so you work faster, and use the extra time to build farms that keep you fed.
- Break the block this is your only source of materials at the start.
- Collect resources everything you gather goes toward expanding your base.
- Upgrade your tools better tools mean faster gathering.
- Build farms a steady food supply keeps you alive through long survival runs.
- Expand your base more space gives you room to add defenses and production before the next raid arrives.

Common questions
FAQWhat should I do first when I start the game?
Break the single block you spawn with — that is the only way to get your first resources. Once you have materials coming in, focus on upgrading your tools and getting a farm started so you are ready before the first raid on night three.
What happens if I die in 100 Days mode?
The mode runs on hardcore rules, so dying ends your run on the spot. You have to start over from day one.
How much time do I have before each raid?
Raids come every three nights, so you get three nights of preparation between each attack.
