From scrap
to empire.

Fabrikon is an idle/tycoon game in the style of AdVenture Capitalist: buy factories, managers switch production to automatic, milestones double the profit, prestige brings permanent multipliers. The entire economy is pure, deterministic mathematics – and it can be tried out right here.

Preview: the real economy

Four of the 24 factories, the same numbers as in the app – including the production chain: the Scrap Collector fills the storage, and the Bolt Works and the Gear Foundry consume from it according to a real bill of materials. Purchase costs grow exponentially, milestones double the profit, a manager switches production to automatic. The rest (three further plants, end products, prestige, boosts, shop, offline earnings) is reserved for the app.

What is real here

  • The cost curve. Every additional unit costs a fixed factor more – exactly the geometric series from economy.ts.
  • The milestones. At 25 and 50 units the factory’s profit doubles, at 100 the cycle time halves.
  • The managers. Once bought, the factory keeps running by itself – that is the “idle” core of the game.
  • The bill of materials. One scrap cycle delivers 10 scrap to the storage, a batch of bolts consumes 2, a gear set 3 – the chain from RECIPES and BATCH.
  • The number formatting. K, M, B, T and beyond – the same short notation as in the app.

Tip: Let the Scrap Collector run first, because without scrap in storage the Bolt Works and the foundry stand still. The first profit makes the manager affordable – from then on the chain runs in its sleep.

What makes the full game

Fabrikon is built on what really keeps idle players hooked – clear goals, noticeable leaps, never a wall without a way out.

24 factories, four plants

Metal & silicon, wood, glass and photonics – from the scrap collector via the fusion reactor to the telescope mirror. Every new factory is a goal worth reaching.

Production chains

Bolts need scrap, chips need wafers, robots need both: the factories supply each other according to a real bill of materials – and end products refine the parts into permanent bonuses.

Managers & automation

Every factory can be automated with a manager. After that it keeps producing, even without further input.

Milestones

At certain unit counts the profit doubles or production gets faster – the reason to always buy “just one more”.

Prestige

Reset everything in exchange for investors who permanently increase the profit. The first restart already pays off after just under half an hour.

Boosts & time warps

Temporary doublings and time warps that credit hours of production immediately – for speeding up, not as an obligation.

Offline earnings

Production continues even when the app is closed. On returning, the earnings from the break are waiting.

Pure mathematics, testable to the cent

The heart of Fabrikon is not a graphic but a formula. The entire economy is stateless, deterministic mathematics – which is why it can be checked by simulation, and why the same calculation also runs here in the browser.

Economy as pure functions

Purchase, earnings and cycle mathematics live in a separate file without state. A test suite checks them with many plausibility runs.

React 18 + TypeScript

User interface in React with TypeScript, state management via Zustand, animations with Framer Motion, styling with Tailwind.

Vite, small bundle

Built with Vite – around 95 KB compressed. Quick to start, quick to test, small to ship.

Capacitor for Android

Capacitor turns the same web code base into the native Android app for the Play Store.

Robust tick loop

Production runs on a clock that keeps calculating correctly even in the background and after breaks.

Graphics in code

Factories, machines and conveyor belts are drawn in code and visibly grow with the upgrade levels.

Where the project stands

Fabrikon is playable, is in closed testing and is currently being prepared for publication. The core and the content are in place; the final polish is under way.

Done

Economy core

Cost curves, milestones, managers, prestige and offline earnings – deterministic and checked by simulation.

Done

Factories & interface

24 factories in four plants, production chains with a real bill of materials, animated production lines, upgrade levels, shift supervisors, shop, boosts and prestige view.

In progress

Polish & balancing

Adjusting the curves so that every section is worthwhile, plus store preparation and tests on real devices.

Next

Publication on the Play Store

As soon as it is ready, the link will appear here.
