This New Puzzle Game Hijacked My Brain — And I Loved Every Second of It

If you’re into puzzle games that really make you think, Kaizen: A Factory Story might just hijack your brain like it did mine. This mechanical puzzle game on Steam, set in 1980s Japan, challenges you to design and optimize assembly lines to mass-produce everyday items — from watches to coffee makers, and yes, even bidets.
- Discover the core gameplay of automating product assembly lines
- Learn how Kaizen combines programming with mechanical puzzles
- Explore the mental challenges of optimizing complex builds
- Understand the nostalgic vibes and inspirations behind the game
Simple Concept, Deep Puzzle Mechanics
Kaizen puts you in charge of creating production lines on a green grid. You get a picture of the item to build, plus all the parts needed. Your job? Connect these parts using gadgets like arms, drills, riveters, and welders. But it’s not just about placing tools — you also program each gadget’s movements step-by-step to automate the entire process.
Early puzzles feel manageable. For example, building a pair of binoculars involved just a few clever steps: attaching eyepieces to barrels, connecting barrels to hinges, and flipping the assembly over. The game even spawns parts automatically based on your setup, keeping things smooth and logical.
The Joy of Cracking the Code
Every time you nail a working build, a green light signals success, followed by a short video showing your machine in action. It’s incredibly satisfying — like watching your own Rube Goldberg machine come to life. This feeling is what makes Kaizen stand out. It’s reminiscent of classics like The Incredible Machine and educational engineering games from the late ‘90s.
But the game quickly ramps up. Complex items like camcorders require you to think about cutting out sections, moving parts precisely, and welding components together. For example, figuring out how to slot a tape deck into a camera body without breaking your entire design can be maddening — but in a good way.
When Puzzle Solutions Take Over Your Mind
One of the most interesting parts about Kaizen is how it sticks with you. Even away from the game, I found myself mentally reworking assembly lines and testing ideas in my head. At one point, I was so hooked that I considered sneaking away at a bar just to finish a tricky weld on my Steam Deck.
The game pushes you to optimize endlessly — fewer steps, fewer parts, less space. But sometimes, the solution demands a complete rethink. That’s part of the charm: the frustration, the trial and error, and the eventual breakthrough.
More Than Just a Puzzle Game
Beyond the mechanics, Kaizen weaves in a subtle story reflecting on the shift from handcrafted goods to mass production in the mid-1980s. It honors the invisible engineers behind these processes and reminds us that human ingenuity can never be fully automated.
Currently, the challenges include cutting and rejoining fabrics to make clothing items like tube socks and jogging shorts, requiring even more intricate planning and precision. It’s a game that rewards patience and creativity, making every success feel well-earned.
If you’re looking for a puzzle game that’s both mentally engaging and oddly satisfying, Kaizen: A Factory Story is worth checking out.
