Factorio for Beginners: 10 Golden Rules to Launch Your First Rocket

Introduction

Factorio is a game about automation, efficiency, and scaling up. For new players, the complexity can be overwhelming. You might build a mess of belts, run out of resources, or spend hours fixing bottlenecks. But fear not: these 10 golden rules will set you on the path to a smoothly running factory and your first rocket launch.

1. Build a Main Bus

The main bus is a backbone of belts carrying your most important resources: iron plates, copper plates, steel, green circuits, and more. By feeding all your production lines off this bus, you avoid spaghetti and make expansion easy.

• Leave space (at least 4 tiles) between each belt line so you can add underground belts later.
• Keep the bus organized: use one side for raw materials, the other for intermediate products.

2. Plan for Expansion

Factorio punishes cramped designs. Leave ample room between buildings and rows. A common mistake is building too compact, which forces you to tear everything down later. Rule of thumb: double the space you think you need.

3. Automate Everything Early

Hand-crafting is a trap. As soon as possible, automate production of key items: iron gears, belts, inserters, and assemblers. Set up a mall (a small area that produces all essentials) so you can grab stacks of belts and inserters without manual crafting.

4. Use Ratios for Smelting and Assembling

Learn basic ratios. For example, one stone furnace takes 0.5 seconds to smelt one iron ore, so 48 furnaces saturate a yellow belt. For green circuits, 3 copper wire assemblers feed 2 circuit assemblers. Use online calculators or experiment.

5. Keep Your Power Ahead

Power outages cause cascading failures. Always build more power than you need. Start with a few steam engines, then scale to boilers and steam turbines. Before expanding, build extra power plants. Monitor your satisfaction percentage in the power menu.

6. Use Underground Belts and Splitters Wisely

Underground belts let you cross lines without mixing lanes. Splitters balance flows. For a main bus, use splitters to pull off resources without starving downstream. Learn to use priority splitters to feed your factory first.

7. Automate Research Constantly

Research is the key to progression. Set up a science pack production line that keeps running. Start with red science, then green, and so on. Always have research queued; downtime is wasted potential.

8. Defend Early and Often

Biter attacks grow stronger with pollution. Build walls, turrets, and ammunition before they become a problem. Use radar to spot nests. Automate bullet production and use armor piercing rounds. Later, switch to flamethrower turrets or laser turrets.

9. Learn to Use Trains

When your bus runs low on ore, it's time for trains. Set up a simple two-way rail network with signals. Use train limits on stations (introduced in 0.17) to prevent multiple trains from clogging. Start with a simple iron ore outpost and a single train.

10. Don't Be Afraid to Rebuild

Your first factory will be a mess. That's fine. Use construction bots (once you have them) to tear down and rebuild sections. Blueprints save time. Copy successful designs from your own factory or the community. Remember: a perfect factory is a journey, not a destination.

Conclusion

Factorio rewards patience and planning. Follow these 10 rules, and you'll avoid early frustration. Keep learning, use the in-game tips, and soon you'll see the rocket launch. Happy automating!
