A retro incremental game where you accept jobs involving disks, decide how to process them, and push an aging PC to the absolute limit. Upgrade your machine, reboot to gain permanent BIOS improvements, and tackle disks that get increasingly hot, risky, and valuable.

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/day in the week to Sep 13 → 0.4/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
Defrag Incremental is a retro incremental game about doing one very specific job on an increasingly overworked 90s PC: defragmenting disks for money.
At first, the job is simple. Pick a disk, choose an algorithm and get it done before the workday ends.
Then the disks get bigger.
Some arrive damaged. Some run hot. Some are worth a lot more than they have any right to be. Your computer gets faster too, but faster hardware also gives you more ways to push things too far.
You don't have all day.
Disks come with different sizes, values, conditions and properties, and taking the most expensive one is not always the smart choice. A job that looks profitable can become a problem if it runs past the end of the shift or your hardware isn't ready for it.
Daily conditions and contracts can also change what is worth doing from one workday to the next.

Algorithms and modes trade speed, reward, heat, wear and safety against each other.
There isn't one setup that is best for every disk. Sometimes you want to finish as quickly as possible. Sometimes keeping a damaged disk alive matters more. Sometimes you just need to get something finished before the clock runs out.
Once a disk is running, you can keep an eye on its health and temperature and intervene when things start going wrong.
Finished jobs give you Defrag Points to spend on the current run. Improve read and write performance, cooling, recovery and the other parts of the machine that are holding you back.
As those upgrades stack up, disks that were painfully slow at the start become manageable and new tiers begin to make sense.
The System Stats panel keeps track of the combined effects of your upgrades, so you can see what the machine is actually capable of.
Rebooting is the prestige layer.
Your temporary run upgrades are reset, but the Reboot Charge you've built up becomes BIOS Chips. These are spent on 53 permanent BIOS upgrades that stay with you between runs.
They unlock new shops, automation, longer workdays, advanced controls and other tools that gradually change how each new run plays.
So every run starts again, but it doesn't start from the same place.
Eventually the computer can take over some of the routine work.
Automation follows a simple set of rules. It can keep things moving on its own, but an attentive player can make better choices about disks, algorithms and risk. You can leave it alone, step in when it matters, or gradually automate more of the job as the system grows.

The money you make from disks is separate from the points used to upgrade the computer.
What happens during the workday follows you home: finished jobs, lost rewards and interrupted shifts affect a separate life-management layer between workdays.
Housing, transport, food and other expenses gradually turn the money you earn at the computer into another part of the progression.
The computer keeps track of what you've discovered and how far you've made it through the game.
New tiers, archetypes, tags and special disks fill out the database alongside personal goals, Byte Bazaar discoveries and your progress outside work.
If seeing 100% next to a database makes something in your brain happy, there is plenty here to fill in.

The whole game lives inside a fictional desktop inspired by the PCs and operating systems of the 1990s: BIOS screens, little utilities, reports, ugly system messages, questionable noises and far too many windows.
The machine starts simple. It doesn't stay that way.
8 disk tiers

Very weird bugs for a simple incremental game; For example, the time hangs after rebooting and it is still not fixed after the first patch. Probably vibe coded, stay clear.
This game is not in a good state at the moment. It is INCREDIBLY frustrating trying to set the screen size to full screen, because as soon as you hit the Options button, the screen goes to the smallest size possible. I had to quit and restart a couple times and just kept in Windowed because I couldn't be bothered to keep messing with it. Also, not an incremental game at all. Idk what the developer was going for, but this is not something I would recommend in the slightest.

Love it! Cheap as chips, and while it has some bugs, the developer is very active. It received several updates on release day.
Its a good and fun little incremental and nostalgia filled treat. Its not perfect and its been review bombed, unfairly imo, but I played it for a good while already and intend to play it some more. In my country it's $3 on sale. Totally worth it afaic.
I admit, partially this is nostalgia because I turned old last year and I remember having to actually use this tool. But really, it's a nice diversion from office work, and I can run it side by side with my work PC - people think I'm actually cleaning up hard drives. It's also fun and more involved than most idle games. I've had conversations with the developer and he/she has been incredibly responsive, working hard to patch bugs and listen carefully to feature requests. The negative reviews are largely baseless - the description, video and screenshots are all very upfront about what this game is and how it plays. It's not supposed to be exciting, or fast paced. It's an idle game. You play it in between working on other things.
The day 1 stability update fixed pretty much every issue with the game I had. On launch it was, to put it bluntly, completely unplayable. The dev however was instantly responding to posts and fixed from what I can see everything very fast. The outcome is this is a really solid incremental that's a lot more active than most but with a lot of really unique elements! I can emphasise with wanting to change things, not being able to change the release date, and having real world issues to fight with. But this is why you don't make major changes a day or 2 before launch 😅
For $3, it was a nice toy and I don't exactly regret buying it. But finding a BC duping bug made it basically meaningless to leave running. If this sort of thing is your jam, go for it, you won't miss the couple of bucks. But otherwise, I'd pass on this one. The Dev's previous game was basically this, minus the progression, but plus defrags from other eras of computing. Honestly, a better buy IMO. Agree with the others: *If* this was vibe-coded, it needs to have the disclaimer in the write-up.
It's a neat game with a nostalgic aesthetic.
It's a really fun game dont get me wrong, but this is nowhere near complete or even in it's playable state. look at the discussion and all you see are people reporting bugs. I cant recommend this game right now, the heart is there but the implementation is very disappointing. The latest update broke my save and it sucked the remaining fun i was having with the game.
Feels vibe coded. I can't really tell that any of the upgrades do anything, so it feels like you are watching a video.
