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.

One of the best computer logic puzzel games, and general overview of data types, I have seen in a long time

A game quality of Zachtronics games, and it's free. Recommend it.
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!
Its is super fun and challenging while at some points it can be frustrating the community is there to help with guides and even the games offical guide
design - excellent, music - good, controls - good, brain work - a lot the only problem i encoutered is that it didn't fill the screen (it caused other problems like not being able to click some buttons) in fullscreen mode but it's fixable by restarting the game
Inconsistent logic or impenetrable explanations. Sensors don't work in a way that I can understand from the description or experimentation.
ZachLike游戏好玩之处在哪儿?我觉得在于和Minecraft机械动力一般的自由创造力,所有puzzle都没有一个固定的答案,无论什么指标你想追求什么就追求什么。 鉴于非英语母语读起来会比较生涩不连贯,在此我分享一下我试出来的汉化方法:(狸猫换太子法) 将韩语ttf文件替换为某个中文的ttf文件,并将language.ini中韩语部分全部(ai翻译)成汉语。务必保证格式的正确(尤其是*号)否则会出现卡死的bug。 不会汉化的可以留言加我好友,我给你一份我的ttf和ini,直接替换就好(部分格式错误可忽略不计) 引用部分我发在官方dc上的话:“this game might be more educational, especially in terms of building logical thinking. players in China, far across the ocean, also enjoy it, and it offers considerable playability and depth. Although I've only played two Zachlike games—Opus and Shenzhen—I find Abidos is no less impressive than these two classics. Perhaps its only drawback is that too few people are playing it, so I can only exchange insights with my good friend who also loves Zach (the one mentioned above). china's payment system does not support PayPal, and I haven't applied for a foreign bank card. although I can't make a donation to the author, I with my friend would carefully study the depth of this game as a way to express my respect.👍”
Worth playing if youve got a mind for either computer science or related topics, you will forget everything about this game after a week of not playing and you will be confused when you replay this game, trust me, guides are necessary to catch back up to speed or with some levels to help with ambiguity but otherwise fantastic without any extra stuff, runs fine
