What makes Fibonex different

Build a factory that thinks in numbers.

Fibonex turns abstract patterns into moving machines: mine values, combine them, filter mistakes, and feed the Collector with a contract your layout can prove.

Contracts

Feed the Collector

Every guided build has a purpose: solve constants, predicates, rates, and exact ordered sequences while wrong values become visible Noise.

Patterns

Read Data Cores

Numbers stay readable on belts and now carry accents for primes, Fibonacci values, and negative results as your factory gets denser.

Logic

Filter the Noise

Use splitters, storage, logic machines, PHYS impulses, and LIGHT beams to separate clean signals from messy factory output.

Build, Copy, Replay

Blueprints, Proof Replay, and FXCH challenge codes bundle the contract, layout, score, and trace so a solved idea can travel.

Install Fibonex like an app

Fibonex is a Progressive Web App. That means the same web game can live on your home screen, open without the browser bar, and keep the quick browser updates. No APK hunt, no store account, no mysterious phone ritual.

Open Fibonex
Android

Chrome or Samsung Internet

  1. Open play.fibonex.app.
  2. Tap the browser menu.
  3. Choose Install app or Add to Home screen.
  4. Start Fibonex from the new home-screen icon.
iPhone and iPad

Safari

  1. Open play.fibonex.app in Safari.
  2. Tap the share button.
  3. Choose Add to Home Screen.
  4. Keep Open as Web App enabled if iOS shows it, then tap Add.

What it does: your phone creates a normal launch icon for the web app. Fibonex still updates from the website, and removing it works like deleting any other home-screen app icon.
