TIS-100 is a difficult indie puzzle game from Zachtronics made with computer programmers in mind. The player will enter instructions in a low-level assembly language to produce programs that move numbers between registers in order to transform inputs into outputs, all in a retro ASCII atmosphere.
Currently available in Early Access, in this latest addictive programming puzzle game from beloved indie developer Zachtronics, you find yourself abducted by a bunch of aliens who immediately put you to work designing efficient factory solutions to them. With a 30+ level complete main campaign, and smart, challenging, cerebral gameplay, Infinifactory is an easy recommendation for anyone who likes a game that makes them think.
Ironclad Tactics is a turn-based strategy game created by Zachtronics, the studio behind The Codex of Alchemical Engineering and SpaceChem. Set in an alternate-history post-U.S. Civil War era, the game pits you against the Confederates as you march your way across the country, one town and one battle at a time. There's a twist, however: steampunk technology is a thing, meaning your infantry units will have to take on ironclad contraptions and well-equipped automatons in addition to gunslingers and musket wielders. It makes for a really entertaining setting, but you'll feel bad for those squishy human soldiers.
The creator of The Codex of Alchemical Engineering and Bureau of Steam Engineering (not to mention the grandaddy of Minecraft, Infiniminer) is back with a full-fledged indie game ready to provide a serious logic puzzle challenge. SpaceChem is anything but simple, anything but easy, and one of the most satisfying puzzle games released. If you can solve its challenges, that is. SpaceChem is a game you'll spend a few minutes learning but weeks trying to master, and its 50+ levels are more than enough to strain your poor brain matter more than it's been strained in quite some time.
