Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 2.29/day in the week to Sep 10 → 5/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Great game
My favorite Zachtronics game. This game owned every moment of my free time from the moment I started working on the first puzzle until I finished the final puzzle. Then I went back and played some more. It starts out relaxing and zen-like, then works its way up to diabolical without ever becoming infuriating. Looking forward to the new content.
kinda same vibes that factorio give when you are doing the visualization in your head to line things up properly and figure out how to build something that makes the right chemical. utilizing instructions to make the parts do what you want is a huge part of it. you can optimize your solution for cost, speed, or area, or just make your solution as clean looking as possible. if you have good visualization capabilities then every single puzzle in this is a satisfying exercise. i recommend learning all the keybinds because they speed the process up a lot. when you get a working solution, it can record a gif of it for you, so you can annoy your friends. beyond the mechanics, the art style and story to this game are cute and interesting. the background art is just sitting in the game files, and they make great desktop backgrounds. one of my top 5 favorite puzzle games.

good puzzle game
With score tracking for speed, cost, and size, there's a ton of challenge for puzzle sickos. Beautiful art, solid narrative wrapper.
I am very stupid, but the game is still pretty fun. Overall, a game for people permanently fixated on maximizing the efficiency of production lines.
这不是化学反应
A great puzzle game. Of the Zachtronics games I've played I found this one the simplest in both mechanics and challenges. Thus it's a solid recommendation for those entering the Zachtronics world of puzzles. Your solutions are scored in comparison to other players in terms of cost, time, and space used. This provides plenty of replayability if you want to optimise your design, especially if you have friends who own the game. Similarly an endless collection of puzzles designed by other players could keep dedicated players amused forever. On the downside, the story line is quite weak. A common frustration was also replaying long solutions to tweak minor errors. The ability to jump to a keyframe would have been nice, although that may have removed a lot of the mental challenge of visualising the answer.
An elegantly designed, very thinky puzzle game. It's so satisfying to watch your machines work.
