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.

finally i can stop booting up my win 95 to defrag my nvme \o/
Great concept, half-baked execution. Way too inactive. Job mechanic only creates irritating interruptions.
Most of the release bugs are fixed.

Great game to play in the background. Far more configuration options than in the demo.
If you liked watching DEFRAG.EXE in DOS, you'll like this game. It is a bit rough around the edges with more bugs than I would have liked, but I think it offers excellent overall value. I hope the dev keeps polishing this.
This is actual crap. If I wanted to actually watch a drive defragment, I'd go get one and do it for real. All I wanted was some involvement, but it's literally click the drive (doesn't matter which one you pick), and then the algorithm (also doesn't matter, the quick one did better than the normal one) and you wait. It's basically paint drying, the game.
Love this game, needs some polish for sure, but the concept is fun and simple.
Takes me back in time, but with less stress concering actual bad sectors :D
As an idle game, Defrag is fine. Style and sounds are reminiscent of the time, numbers go up, unlocked automation takes care of menial tasks, reboot, restart, repeat but most other design choices are half baked. You eventually get used to the disconnect between the workday and task clocks. The “real” life expenses try to hint at something bigger outside the loop but you quickly realize has no impacts at all (though I’d love to have $2.5M in savings after a year of work) and only serve as arbitrary limits on output. New algorithms suggest some nuance in what process is chosen but I don’t recall ever worrying about disk health or heat (and automation doesn’t care either). Hopefully lessons learned can be expanded into a sequel, however if this is all there is going to be it’s worth a try if you have any reverence for the aesthetic.
Juegue este juego al 100% para que no lo tengas que hacer, es un juego altamente vibecodeado publicado por alguien que larpea que le gustan los sistemas operativos y hardware viejo pero la jugabilidad tampoco es satisfactoria, dista mucho de juegos incrementales de igual valor en calidad y hasta diria que cualquier incremental gratuito ya sea descargable o en web lo supera desde lo jugable (es un simulador de esperar) siendo que la propia mecanica de renacimientos es altamente aburrida, las mejoras algunas ni se sienten, cosas como el tiempo estimado esta mal programado siendo 8 horas el maximo pero oh sorpresa algunos discos se pasan de eso y el tiempo pasado se queda clavado ahi tambien sin que el disco se complete, no puedo recomendar este juego bajo ninguna ocasion, ni siquiera a los fanaticos de lo viejo en la informatica porque esta hecho con muy poco amor y tiene mecanicas altamente inutiles como el control financiero al final de cada dia que al final oh sorpresa tampoco funciona bien porque es practicamente imposible quedarse pobre o influir de una manera significativa en ese sistema, escribo esto como si fuera el pulover azul de cortazar para que sientan lo que se siente jugar a este juego plenamente aburrido y sin proposito
