About the Game
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.

Official update history
Today's update adds our final weekly bonus puzzle, the DESIGNER'S NOTEBOOK, which is actually not a puzzle but a collection of TWELVE new puzzles based on existing puzzles. What?
During development, I had originally imagined that about 1/3 of the puzzles in the game would be variant puzzles, which required the player to conditionally build one of two different products, in the spirit of the just-in-time manufacturing revolution that inspired the game. One of my favorite examples of this was the "video recorder" puzzle, which originally required you to build both VHS and Betamax variants:

(Traces of this remain in the story, where we learn that Ozeki-san is a devoted Betamax fan.)
We prototyped but quickly cut this feature, as I felt it was too confusing for a game whose entire point was to minimize the "unnecessary complexity" of my previous games. After we released the game, however, I started exploring ways to add some harder puzzles, and ended up coming back to this idea. I re-implemented the feature, updated it to fit the final design of the game, and started resurrecting the original versions of puzzles with variants.
The Designer's Notebook, available at the end of the bonus chapter (unlocked after beating the game's main story), includes 10 new variant puzzles based on puzzles from the main campaign. There are also two non-variant puzzles: my original (and harder!) version of the "pachinko machine" puzzle, and an alternate version of the "chess computer" puzzle suggested by a player on the Zachtronics / Coincidence Discord that is very hard but also very funny. (I have yet to beat it... it's probably solvable?)

Today's update adds a new weekly bonus puzzle, the TOY CASH REGISTER!
"Get kids started early on understanding the transactional nature of modern life! This toy cash register includes a light-up display and drawers to enable buying, selling, and giving change. It's all about the Yukichis (Benjamins)!"
Today's update adds a new weekly bonus puzzle, the SLOT CAR TRACK!
"Even though it was clear by the late 80s that video game racing would gain popularity over the old hobby of slot cars, someone at Matsuzawa apparently had enough of a soft spot for it to approve the release of this entry level track."
Today's update adds a new weekly bonus puzzle, the DOLLHOUSE KITCHEN!
"This kids' kitchen playset originally included real heating elements along with realistic flame and smoke effects, but those features were nixed before it went into production due to safety concerns. Nevertheless, the product was a hit!"
This is one of my favorite puzzles that I've made for the game so far. It's quite challenging!
Today's update adds a new weekly bonus puzzle, the BOOMBOX!
"Bring the beats with Matsuzawa's biggest boom box to date! The whopping twelve "D" batteries it requires will definitely set you back some cash, but the volume that enables will guarantee you never lose another boom box battle!"
