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 → 0.5/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

Maybe some young people do not understand what it is to have something to do and go to other task as defrag your disk, but for old people as I this was what I do instead of cleaning my room as an excuse to having something important to do instead. It take some hours to get to the real deal as making the BIOS more powerful but when it hits you will enjoy a really faster computer and you start to feel your growth. If you do not have patience why would you try a game about defrag a disk??? Again this is not for young poeople that really need the dopamine hit every 30 seconds.
I was excited to play this game, however, it's boring and after playing for 62 minutes by save broke.

A fun little incremental / idle game that captures the nostalgia of the old MS-Dos era disc defragmenters complete with classic HDD sound effects. If you like retro computing, or incremental games you'll get a lot of fun out of this one. The game still has a couple rough edges but the developer has been very active in resolving reported issues and implementing feedback.
The game released severely half-baked. It feels like it still needs several months of Early Access to get to a decent baseline. The developer seems to be fixing the leaks, but not addressing the major structural problems that cause the ship to leak. A text book example of why you should not release with zero play testing.
Things I like: - Cheap - Background game (if! you turn on pause work day, otherwise you lose workday time in menus/selecting which isnt explained) - number goes up brain happy Things I found annoying: - Menu items arent explained, - Audio is grating/bland, could have some cool music or atleast audio to signify a disc is completed - Display mode 1x and 2x are abhorrent and shouldnt exist, 4x is default and resonable (should be x1), - No manual saving, you the lose entire day on exiting game - There are keyboard shortcuts for opening menu's but no actual keyboard menu navigation otherwise - bugs Bugs I have encountered: BIOS Upgrade Start runs with +300 DP. (Never applied, tried prestieging twice) cash amount (awarded at end of work day) resets on exiting the game. BIOS (presteige menu) purchases are inconsistent in showing buyable upgrades. (eg Need BC for 2BC upgrade but shows I can buy 7BC upgrade. Ultimately due to the Need BC upgrade I couldnt even purchase it) End of day comments/events dont always fit screen (4x mode) Generally there is a lot of room to improve and could be a great game but in the current state it is quite frustrating
If you like the satisfying feeling of the defrag-process (remember the 90's!) - you /could/ like this game. This is a game, after having achieved the automation tools, that you let running while playing another game...
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've had nightmares like this. A+
The game in its first hours of release did have some bugs, but that is not longer the case. Getting that out of the way. So! It's a fun little "idler" incremental game. The aesthetic and interface definitely do some heavy lifting here, but its undeniably charming. The upgrades are a bit "long form" so it'll definitely keep your second screen company for a bit. For a devs first game, I can definitely see the bones of something great here. It just needs a few extra layers of gameplay for some, but I have no complaints.
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.
