ABI-DOS: The Ultimate Automation Puzzle Challenge.
In ABI-DOS, you build circuits to manipulate and guide UBITS (colored digital blocks) toward specific goals based on the given documentation. By strategically placing wires and instruction blocks on a microchip, you manipulate inputs to achieve desired outputs—whether it’s fixing corrupted files, recovering damaged .png images, or simulating particle trajectories. ABI-DOS challenges you to meet strict specifications through inventive problem-solving.

No programming experience is required, as everything is explained in-game. The focus is on assembling logical solutions within space and operational constraints rather than on real-world programming concepts.
The puzzles are challenging and offer no predetermined solutions, allowing for multiple approaches. Each level starts with a blank canvas, giving you the freedom to create your own unique solution from scratch.
You are encouraged to optimize your algorithms, fostering creative exploration and friendly competition as you compare solutions with friends and on global leaderboards.

With over 50 puzzles and more than 50 hours of gameplay, ABI-DOS offers extensive content for players to delve into.
The work is overseen by the system's Admin, a mysterious figure who is not what he seems. Set in a retro-punk world, this enigmatic presence adds an extra layer of intrigue as you uncover the deeper mysteries of the system.
Drawing inspiration from Zach-like games, ABI-DOS pays homage to its predecessors while offering a fresh perspective on the assembly puzzle genre.

This is a great programming game, truly top notch. The quality here is insane for how incredibly free it is.
One of the best computer logic puzzel games, and general overview of data types, I have seen in a long time
I was going to wait till I had completed the game before posting a review, but I'm enjoying optimising the puzzles so much, that would take quite a while. :D And now I just recently "discovered" the bonus challenges, which is taking it to a whole new level. This is definitely my favourite zach-like EVER. It ticks all the right boxes. I even stopped playing Last Call BBS (for now), as I'm enjoying this so much! I must confess I was confused with some mechanics at the start, and I probably still don't understand how priority works (it's pretty straightforward, but for some reason, it didn't seem to work for me, so maybe I was just making some stupid mistakes). Highly recommended game if you like logic puzzles, programming, etc. What am I saying, this game is free, so go play it already!

Simple rules, deep connections. ABI-DOS tries to give you the simplest tools and makes you do the hardest with them, atleast not in the intro levels. Numbers, adders, subtractors, multipliers, the very simple bolts. If you have the brains, then give it a try. It's free anyway... P.S: I'm not done with it yet
Premetto che ho preso il game quando era free perché originariamente non ero molto convinto dell'acquisto considerando che l'Italiano non è una lingua supportata, ma mi sbagliavo... Se vi piacciono i giochi puzzle logici ecc tipo Zachtronics prendetelo, anche se non vi piacciono visto che ora è Gratis... in Inglese ma Gratis!!! La meccanica all'inizio può sembrare complicata, ma questo si risolve leggendo bene (Tks Google translator) il manuale PDF allegato ( stile Zach, tenetevelo a portata di Mouse ). Sono quasi alla 400esima ora di Play su un portatile con montata sopra una 920 e devo dire che alcuni livelli mi hanno veramente messo alla prova ma con grande soddisfazione riuscendo a rientrare o superando la media... si, gli Highscores sono online e divisi come nei classici Zach per Cicli, superficie utilizzata e simboli (istruzioni) usate più un bonus se rientrate utilizzando la superficie suggerita dallo sviluppatore, quindi per ogni livello potete sbizzarrirvi a riprovare a sperimentare soluzioni migliori per ogni tipologia di risultato... (avete 12 sloti di salvataggio per ogni livello); quindi che dire, 400 ore spese bene ... se avete problemi sono a disposizione qui su Steam
Nice
High quality and fun
I'm on the team of pronouncing it "Abby-doss". I don't trust anyone on team "Ay-bee-eye-dee-oh-ess".
