Many players reach mid game in Alchemy Factory with a familiar frustration:
They have read the Codex.
They have checked ratios.
They have tried planners, calculators, and blueprints.
Yet the factory still becomes unstable.
This page explains why system knowledge itself stops being predictive in mid game —
and why this is not caused by missing tools, incorrect math, or poor planning.
How to Read This Page
This page is not a tool, a calculator, or a planner.
It exists to explain why those tools stop being sufficient in mid game.
If you are looking for numbers, layouts, or fixes, this page may feel abstract. That is intentional.
Use this page when:
- Your factory follows the rules but still behaves unpredictably
- Calculations look correct but production degrades over time
- Planners stop matching what actually happens in-game
After reading this page, most players continue in one of two directions:
- To understand specific failure symptoms, see:
- To understand how to plan without calculators, see:
- Mid-Game Planning Without Calculators
Think of this page as a bridge between knowing the rules
and operating a live system.
What Players Mean by "Codex"
When players refer to the *Codex* in Alchemy Factory, they usually mean the **in-game system documentation** that explains how the factory works.
The Codex describes:
- Recipes and conversions
- Individual machine behavior
- Core system rules
- Basic calculation logic
For early progression, this information is sufficient.
Small factories behave close to these descriptions.
Inputs produce outputs.
Ratios feel stable.
Problems are easy to isolate.
This naturally creates an expectation:
"If I understand the systems well enough, I should be able to plan everything."
Mid game is where this expectation stops holding.
What System Knowledge Explains — and What It Cannot
System knowledge explains how individual parts behave.
It does not attempt to describe how multiple systems interact under load.
As factories grow, mid-game setups introduce:
- Longer transport distances
- Competing fuel demand
- Storage pressure and buffering
- Dispatch timing mismatches
- Power delivery instability
Each factor is understandable on its own.
Together, they create behavior that is technically correct but practically unstable.
Nothing about the system rules is wrong —
but the system is no longer linear.
The Mid-Game Scaling Shift
Early factories scale by addition.
Mid-game factories scale by interaction.
This is the key transition.
At this stage:
- A correct ratio can still stall
- A powered machine can still idle
- A planned layout can slowly degrade
Not because rules changed —
but because system state now matters more than system definition.
This is when players feel:
"Everything is correct, but nothing works."
That feeling reflects the system accurately.
Why Calculators and Planners Lose Predictive Power
Calculators and production planners are built on a shared assumption:
They model static conditions.
They are effective at calculating:
- Input → output relationships
- Isolated machine throughput
- Ideal ratios
They do not model:
- Time-based fuel depletion
- Belt congestion propagation
- Dispatch priority conflicts
- Power draw spikes across systems
As factories grow, real behavior increasingly diverges from these assumptions.
This is why planners feel reliable early —
and incomplete in mid game.

Knowledge vs. System State
System descriptions explain what should happen.
Mid game is dominated by what is happening right now.
Common examples include:
- Fuel lines that appear sufficient but drain over time
- Buffers that stabilize one subsystem while starving another
- Power networks that fail only after one new machine activates
These are not rule violations.
They are state interactions — and they are intentionally left for players to observe and adapt to.
This is the point where more information stops improving outcomes.
How Experienced Players Use System Knowledge
Experienced players still use the Codex and planners —
but differently.
Instead of planning entire factories, they:
- Validate small subsystems
- Overbuild critical inputs
- Introduce buffers intentionally
- Observe behavior under load
- Rebuild without preserving theoretical balance
Tools become references, not solutions.

A Design Boundary, Not Missing Information
It is tempting to think:
"The game needs a better planner."
But Alchemy Factory is designed around adaptation, not perfect foresight.
Mid game is where optimization stops being sufficient
and resilience becomes the primary skill.
System knowledge still matters.
Calculators still matter.
Planners still matter.
They simply stop being enough on their own.
Final Notes
- ✔️ System descriptions are accurate
- ✔️ Calculators work within defined assumptions
- ✔️ Planners become incomplete as systems interact
- ❌ Mid-game instability is not caused by missing information
If the game feels unpredictable, that is not a mistake.
It is the moment where systems replace formulas.
