Fibonex Handbook

Fibonex is a factory game about numbers. You build miners, conveyor belts, and machines. In the end, the right numbers should reach the Collector. That is how your factory proves a pattern.

What is the goal?

Every level has a Contract. A Contract says something like: "The Collector needs this number" or "The Collector needs these numbers in this exact order".

Your job is simple: build a small factory that creates those numbers and sends them to the Collector. If a wrong number arrives, it counts as Noise. Less Noise means your factory is working cleanly.

Collector

The large center of the world. Contract numbers are delivered here.

Contract

The level goal. For example: "Send 5" or "Prove 34 -> 55 -> 89 -> 144".

Noise

A wrong number that reaches the Collector. It is not fatal, but it shows that something is messy.

Proof

The proof that your factory solved the Contract. You can watch it again as a replay.

Quick start

Start screen with Play, Level Select, Sandbox, and Play Online
Start screen: choose Play for the guided introduction.
  1. Open play.fibonex.app.
  2. Click Play if you want to learn step by step.
  3. Read the mission at the top. It tells you which number the Collector needs.
  4. Choose a tool at the bottom, for example Miner or Conveyor Belt.
  5. Build the path: mine a number, move it on belts, deliver it to the Collector.
  6. Press Escape or choose the hand tool when you want to look around again.
Remember: Find number, place miner, draw belt, feed Collector.

The screen

In the tutorial, the mission is shown at the top. The build dock is at the bottom. It contains tools and groups such as Belt, COMN, Math, PHYS, and LIGHT. In Sandbox and Online mode, the top area is quieter because you build freely.

Mission bar

Shows the current goal, such as the next number for the Collector.

Build dock

This is where you choose miners, belts, machines, signs, and movement tools.

Map and theme

At the top right, you can open the large map and switch the visual theme.

Proof

After a solved Contract, you can watch the proof again.

The most important blocks

Block What it does When you need it
Miner Mines a number or an operator from a resource tile. At the start of almost every production line.
Conveyor Belt Moves numbers and operators across the world. For routes to the Collector or to machines.
MATH Combines A, an operator, and B into a result. When you need to calculate something, such as 3 + 4 = 7.
Splitter Splits one stream across multiple outputs. When one belt should serve more than one target.
Storage Stores items. When a path is blocked for a moment or needs a buffer.
Sink Consumes items. When you want to remove wrong or extra values.
Sign Places a note on the ground. For your own reminders in Sandbox and Online worlds.

Later, you will see more machines: IF, Logic, Register, Counter, Delay, Constant, Random, PHYS, and LIGHT. You do not need to learn everything at once. The first levels introduce the important ideas one step at a time.

Examples

Example 1: Deliver one number directly

The Contract needs 5. Place a Miner on a 5 tile. Draw a Conveyor Belt from the Miner to the Collector. When the 5 arrives, the Contract is solved.

  1. Find a 5 tile.
  2. Place a Miner on the 5.
  3. Draw a Conveyor Belt to the Collector.
  4. Wait a moment until the number arrives.
Example: a miner mines 5 and a conveyor belt sends it to the Collector
Direct route: one number travels cleanly to the Collector.

Example 2: Build 3 + 4 = 7

Some target numbers are not lying on the ground. For 7, you need a MATH machine. It receives numbers and an operator, then produces the result.

  1. Place Miners on 3, +, and 4.
  2. Send all three items to the MATH machine.
  3. Send the MATH output to the Collector.
  4. When 7 arrives, the proof counts.
Example: 3, plus, and 4 enter a MATH machine and produce 7
MATH example: 3, +, and 4 become the target number 7.

Example 3: Fibonacci Proof

Later in the tutorial, the Collector needs a sequence: 34, then 55, then 89, then 144. The order matters. If 89 arrives before 55, the Proof does not match.

A good solution makes the numbers reach the Collector in the right order. Use longer belts or buffers if one number arrives too early.

Example: solved Contract with Proof 34, 55, 89, 144 and a Challenge code
Proof example: the Collector accepted the correct sequence.

Proof, Replay, and Challenge code

A Proof is not a magic word. It is the trace of your solution. Fibonex remembers which values arrived, how much Noise happened, and which factory solved the Contract.

Proof Replay

Runs your solution again more slowly, so you can see which numbers were accepted.

Copy Challenge

Creates a code with Contract, Blueprint, origin, resources, score, and replay trace.

FXCH1 code

A shareable Challenge code. It is not a full online save file.

Verification

A Challenge should be recalculated by the server. That keeps the proof fair.

In plain words: the Proof shows that the result is correct and that the path to the result worked.

Sandbox, Online, and Blueprints

Sandbox example with Save, Load, Blueprint, Copy, Paste, Online, Public, and Pro
Sandbox: build freely, save locally, and test ideas.

Play

Guided tutorial levels. Best for your first run.

Level Select

Direct access to math levels without the assisted tutorial.

Sandbox

Free building with local browser save slots.

Play Online

Online worlds with an account, a private world, and public multiplayer.

Blueprints are copies of building layouts. They let you reuse or share part of your factory. Sandbox and Online modes include comfort tools such as copy, cut, and paste. The tutorial hides these tools so the learning path stays clear.

Tips when something does not work

  • No number arrives? Check that the Miner is placed directly on a number tile.
  • A belt stays empty? Check that the belt points in the right direction.
  • The wrong number arrives? Send it into a Sink or rebuild the route.
  • The Proof arrives in the wrong order? Make one route longer so the later number arrives later.
  • Lost the view? Press Home or open the map with M.
  • On a phone: take your time. Choose a tool first, then tap or drag carefully.
For parents and teachers: Fibonex makes math visible as cause and effect. Players see how numbers are produced, moved, and checked.
