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): 0.29/day in the week to Sep 10 → 0.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.
About
The year is 1986 and you are David Sugimoto, born and raised in South Bend, Indiana. Thanks to a family friend, you’re headed to Japan for your very first job at Matsuzawa Manufacturing.
Japan’s economy is booming. They’re looking for smart, young, motivated business professionals just like you. You’re going to go get to live that 80s executive life and jet-set around the globe, right?
…Right?
Initially promised a job with the international sales team, you show up at your new job and it isn’t a shiny office. It’s one of Matsuzawa’s old factories in the outskirts of Tokyo. You’re quickly put to work designing automated production lines. Do you have what it takes to survive as a rookie thrust into the fascinating world of factory automation?
From the creators of Opus Magnum, SpaceChem, and Infinifactory comes Kaizen: A Factory Story — another masterfully engineered game.
Weld, rivet, cut, and drill the optimal design and share your solutions to build the simplest, fastest, and sleekest items in your factory. Export animated GIFs to show them off.
But wait! There’s more! In case you want to take a break from factory life, you can spend your days playing Pachi-Sol, an exciting new pachinko-themed solitaire game.

정말 재밌어요 효율적으로 설계하고자 하는 욕심을 버릴 수만 있다면...
I love this game for small sessions when I want to relax.
a real visual treat, fun puzzles that aren't painfully hard but have plenty of ways to go back and try to solve them in different ways. if there's one thing i would wish for it would be a custom puzzle system, even though drawing the sprites for it would be a ♥♥♥♥♥. i just KNOW we'd go crazy with it
Great little puzzle game with no time pressure and lots of scope for ingenuity. Lovely little story scenes and music too. Great fun.
I skipped the story, so I can't really comment on that, but the gameplay feels more relaxed than other Zachtronics games and is just really chill. It's fun, I like it. yeah
This game is Infinifactory and Opus Magnum badly mashed together. Or possibly Infinifactory and MOLEK-SYNTEZ, but you can lay your own tracks, so Opus Magnum it is. I wish there had been literally any other element to the puzzles that wasn't 'yeah you have all the blocks you need in mostly the shape that you need them, now go make them fit together'. Make us actually have to *assemble* things, dangit. Also the solitaire is weak and arbitrary.
So, following the closure of Zachtronics, I feared that the genre of 'programming like puzzler' games was going to disappear. Fortunately, it turns out the closure of Zachtronics was more of a rebranding than a real closure, and this game from the new studio Coincidence is a true Zach-like game, though this time with a voice-acted story. The story is best described as 'cosy' and the voice acting does as a surprising amount to make it feel more alive than normal Zach-games. I am glad to see the team hasn't left the industry after all and whilst some others have entered this genre of game, this team are still the kings of it.
