About the Game
Beltmatic is a tiny, brain-pleasing factory builder where the resource you're harvesting is numbers and the upgrades are mathematical operators. You start by extracting digits from the world map, route them onto a conveyor belt, and feed them through plus, minus, and multiply buildings until the output matches the target the hub is asking for. Hit the target, unlock new buildings, expand the network, repeat with progressively gnarlier targets.
It scratches the same itch as Factorio or Shapez but at a fraction of the size — the entire install weighs in at 68 MB, and the game's deliberate pacing means a single-session playthrough is realistic. Notional Games has been steadily patching since the March 2024 release; this download is build 14718838 (the most recent stable version).
Packaged with CSF + Goldberg, so the game is fully offline-playable, achievements unlock locally through the Goldberg stub, and there's no Steam client requirement. Single-player only — no multiplayer mode exists.
