A number factory puzzle

Build. Calculate. Automate.

Extract numbers from the grid, route them through a living network of belts, and combine them into exactly what your Hub needs.

The production loop

Turn raw numbers into a working system

Every target is a new engineering problem. Design the route, choose the right operations, and keep the line moving.

Tap rich number deposits and pull a steady stream of values onto your factory floor.

Draw belts to move numbers around your factory, then build Hyper Belts for faster routes.

Add, multiply, subtract, divide, exponentiate, or build your own reusable functions.

Feed the exact target into the Hub, complete the level, and unlock the next challenge.

Your machine floor

Start with simple belts and extractors. Unlock a deep set of logistics and mathematical machines as your factory grows.

Built to keep growing

BeltFactory keeps raising the target while giving you better tools to solve it. Refine old lines or rebuild everything around a smarter idea.

∞

Hand-crafted early challenges lead into deterministic endless progression.

⌘

Save complete layouts, reuse proven designs, and build machines inside machines.
