$6.99Beltmatic Arithmetic on a conveyor belt
Turn digits into bigger numbers with belts of adders and multipliers, at your own pace.
Is Beltmatic worth it?
Beltmatic is worth it if…
- you like the building half of factory games more than the resource juggling
- you enjoy a quiet arithmetic puzzle more than a twitchy one
- you want a relaxed automation game to unwind with, no timers and no failure states
- you liked Shapez and want a stripped-down cousin built entirely around numbers
- you are looking for a short, satisfying game for a few evenings rather than a hundred hours

Arithmetic as a production line
Every target number is a small puzzle. 79 is prime, so multiplying your way there is out, and stacking 79 ones is a waste of belts. The trick is to build something nearby instead: 80, which factors neatly, then subtract 1 at the end. That is the whole appeal. You are not building the number you want, you are finding a route to it through the operations you own.
You start with nothing but addition, so early lines are chains of ones. Deliver enough to the hub and you level up, unlocking bigger starting numbers, then multiplication, subtraction, division and exponents, each one opening new ways to reach the next target. Old lines stay useful too: a unit that reliably makes 100 can be copied and pasted anywhere on the map whenever a target calls for it. Fair warning, the loop of making numbers out of numbers does get samey after a while.
What should you know before playing?
Can you play it solo and at your own pace?
Yes. It is a singleplayer game with no timers and no way to lose, so nothing pushes you to build faster than you want. The whole thing is about deciding how a number gets made, and that decision can take five minutes or an evening. Lines churn out results in the background while you plan the next one, which makes it easy to pick up and put down.
Do you need to be good at math?
No. The game is easy to grasp from the first minute, and the arithmetic involved is closer to a "make 10 from these digits" puzzle than anything heavier. The interesting part is spotting that 79 sits one step from 80, or that two mid-sized numbers multiply into a huge one. If you can add and multiply, you can play. The minimalist visuals also mean the whole system stays readable even when your factory sprawls.
How long does the game last?
It is a shorter take on the factory genre: a solid stretch of evenings rather than an endless hobby. Once you have all the operators and upgrades, the targets keep getting bigger but the ways of making them stop changing much, so the late game repeats itself. As a compact, well-paced introduction to automation games, it does its job and then politely ends.
