Oxygen Not Included -

Use 25x25 pixel cells to represent the game's tile grid. You can color-code cells for different materials or gases.

A Self-Powered Oxygen Machine (SPOM) typically uses Electrolyzers to split water into oxygen and hydrogen. Draft a design that uses a "gas-sorting" dome: hydrogen rises to the top to power a Hydrogen Generator , while oxygen is cooled and pumped to your base. oxygen not included

If you prefer in-game planning, the Blueprints mod on Steam allows you to "copy and paste" successful designs from one area to another. Critical Math for Your Draft Use 25x25 pixel cells to represent the game's tile grid

Drafting a layout or "paper" plan for Oxygen Not Included (ONI) is a common strategy to manage its high complexity. Because the game requires managing thermodynamic systems, gas ratios, and power grids simultaneously, players often use external tools like or graph paper to design systems before building them in-game. Essential Systems to Draft Draft a design that uses a "gas-sorting" dome:

Use logic gates (AND, OR, NOT) to automate mundane tasks. For example, draft a circuit that turns off coal generators when batteries are full to save fuel. Planning Tools

When creating your blueprint, prioritize these core "early-to-mid-game" modules:

Useful for quick spatial sketches of room layouts and "pipe spaghetti" management.
