Simple guide

Fibonex Handbook

Fibonex is a beta 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?

Guided builds and proof contracts give your factory a target. 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 factory 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 trace that shows your factory solved the Contract. Online receipts are verified by the server.

Quick start

Start screen with Play, Sandbox, and Play Online
Start screen: choose Play for your saved offline Home Factory.
  1. Open play.fibonex.app.
  2. Click Play to continue your offline Home Factory.
  3. Start with the Collector hint: mine a number, move it on belts, then make bigger numbers.
  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. Your offline progress saves automatically. Use the menu Save/Load dialog when you want manual slots, Quick Save, or Quick Load.
  7. Use Play Online later for server-verified proofs.
  8. 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 Home Factory starter, the current task is shown at the top. The build dock is at the bottom. It contains tools and groups such as Belt, COMN, Math, PHYS, LIGHT, and Menu. 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.

Menu

The in-game menu opens theme, camera or character mode, stats, controls, map, Save/Load, research, notes, feedback, and account actions when available.

Proof

Local proof checks can summarize what arrived. Online, a private world can create a server-verified proof receipt.

RES

The RES chip opens a resource overview with items from inventory, storage, sorters, and Collector credit that can pay build costs.

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.
SORT Stores and routes a small filtered item buffer. When one input stream should be split by values such as even, odd, prime, or comparison rules.
PWR Turns positive number items into network energy. When machines should receive a work bonus or REF needs power.
REF Refines Tech Ore into upgrade kits. When you want building upgrades or PWR batteries.
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 Home Factory starter and Research path introduce the important ideas one step at a time.

Resources, RES, PWR, and REF

Most early blocks are free to place, but some infrastructure has a build cost. The RES chip shows what you can spend from your character inventory, nearby world storage, sorters, and Collector credit. You do not need to feed those items in a special order.

Tech Ore

Tech Ore is mined with normal miners after TEC mining research. Mining progress is shown on the miner.

REF

The 3x3 refinery buffers 3 Tech Ore, then spends about one minute refining one upgrade kit while powered.

PWR

PWR generators burn positive number items, power lines carry energy, and batteries buffer shortages.

Build costs

Power lines, generators, and batteries show their required items in the dock. Missing items are shown directly in the UI.

Examples

Example 1: Build 2 + 3 = 5

The Contract needs 5. Place Miners on 2 and 3, feed both into a MATH machine, then draw a Conveyor Belt from OUT to the Collector. When the built 5 arrives, the Contract is solved.

  1. Find 2 and 3 tiles.
  2. Place Miners on both numbers.
  3. Feed A and B into MATH.
  4. Draw OUT to the Collector.
  5. Wait a moment until the number arrives.
Example: miners feed 2 and 3 into MATH, then OUT sends 5 to the Collector
First route: numbers become a result before the Collector accepts them.

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

As your factory grows, Fibonacci numbers can be built as sums: 13 + 21 = 34, 21 + 34 = 55, and 34 + 55 = 89. A good proof setup makes the source values first, then combines them into the next value.

A good solution keeps the route readable: resources above, MATH in the middle, Collector below.

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

Proofs, Receipts, Atlas, and Leaderboards

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.

Run summary

Shows accepted values, Noise, trace, belts, and building counts after a local proof check.

Online ProofReceipt

In a private online world, the server can verify your Collector run and create a signed receipt.

Atlas

Publish an approved proof receipt so other players can see the run without importing your world.

Leaderboards

Each featured, beta, or weekly contract has its own ranking view.

In plain words: local replay helps you understand a solution. Online receipts are verified by the server so public Atlas and leaderboard runs stay fair.

Sandbox, Online, and Blueprints

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

Play

Your persistent offline Home Factory. Best for your first run and for Steam-style offline play.

Sandbox

Free building with the same local save slots; Desktop builds use save files, browsers use IndexedDB.

Play Online

Online worlds with an account, a private world, Proof Library, Atlas, contract leaderboards, and staff-gated public-world infrastructure.

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. Guided starter flows keep the focus on the next build step so the learning path stays clear.

Beta progress

Fibonex tracks lightweight progress on your device so you can see what you have already solved. This is a local guide for you, not an online anti-cheat score.

Local markers

Solved and Clean markers can show which local tasks or proof checks your browser has completed.

Proof badges

Featured and beta proof contracts show Done or Clean when your local browser has completed them.

Weekly contract

A rotating community contract gives the beta a fresh target for Atlas and leaderboard runs.

Progress dialog

Open Stats in the in-game menu to see local story, math, clean-run, proof, and weekly progress groups.

Controls

Esc Hand tool / clear selection R Rotate G Toggle grid M Open map Home Recenter camera Ctrl/Cmd + Z Undo offline placement 1 - 6 Quick build slots T Toggle build dock and quick toolbar L Sign K Camera or character mode E / I Inventory F Pick up Q Drop P Respawn

WASD or the arrow keys move either the camera or the character. It depends on the current mode. Press K to switch modes. The top-right chart button opens Beta progress.

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.
  • Ready for public proof? Use Play Online and create a server-verified receipt in your private online world.
  • 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.
