is a minimalist factory automation game where numbers are the primary resource. Released in March 2024, it combines the logistics of games like Factorio with mathematical problem-solving. 🔢 Core Gameplay Mechanics
The game revolves around extracting raw numbers and processing them to meet specific hub requirements.
Extraction: You place extractors on number patches (initially only 1s) scattered across an infinite grid.
Operators: You unlock mathematical buildings (Adders, Subtractors, Multipliers, Dividers) to combine raw numbers into complex targets.
Logistics: Use conveyor belts to transport numbers to a central Hub. Bridges allow belts to cross without mixing streams.
Progression: Delivering requested numbers unlocks new levels, buildings, and upgrades. beltmatic
Beltmatic: A Study of Mathematical Automation and Logistics Introduction
Released on March 29, 2024, by Notional Games, Beltmatic is a casual factory automation game that strips the genre down to its most abstract and academic core. Unlike traditional factory games like Factorio or Satisfactory that focus on resource management and defense, Beltmatic revolves entirely around the manipulation of integers through mathematical operations. Core Mechanics and Gameplay
The game presents players with an infinite square grid where basic integers are extracted and processed.
Extraction: Players place extractors on the map to harvest raw numbers, such as 1s, 2s, or 3s.
Operators: Buildings perform arithmetic operations including addition, subtraction, multiplication, division, and exponentiation. is a minimalist factory automation game where numbers
Logistics: An expansive conveyor belt network connects these operators to deliver the correct results to a central "HUB" to level up.
Upgrades: Progressing through levels unlocks new buildings and upgrades that improve the speed and efficiency of all operators. Advanced Engineering: The "Make Anything Machine" (MAM)
A significant milestone for experienced players is the construction of a Make Anything Machine (MAM).
Building Number Factories in Beltmatic - a blog by biggiemac42
This is where the magic happens. You feed two belts (input A and input B) into a machine. Adder: Output = A + B Subtractor: Output
To create a 10, you could route two 5s into an Adder, or a 2 and a 5 into a Multiplier. The puzzle is choosing which recipe uses the least belt space and the shortest travel time.
What makes Beltmatic addictive is the moment you stop thinking like a gamer and start thinking like a compiler.
For example, to produce the number 100, a novice builds: (5×5)×(2×2). That’s four multiplications. A veteran realizes: 10^2 is cleaner, but you need a 10 first (5×2), then feed that 10 into an exponentiator with a second input of 2. Suddenly, your factory has half the machines and ten times the throughput.
The game rewards mathematical fluency. You begin to see every number as a factorization tree. You start optimizing for "lowest machine count," then "highest items per minute," then "most tile-efficient layout." It’s Factorio’s endgame optimization without ever building a single inserter.
As you progress to higher targets (thousands, millions), you cannot brute force the math. You must design modules. You will build a "Prime Number Generator" section, a "Power of Two" farm, and a "Subtraction" pit for creating odd numbers.
The final levels of Beltmatic feel less like a factory and more like programming in an esoteric language where the only syntax is conveyor direction. You stop seeing belts and start seeing functions. f(x) = x * 2 becomes a physical loop. g(x) = x / 2 becomes a splitter.
