In each level of Robot Unlock, your goal is to program a path for your Executor robot to travel around a series of command tiles that alter the robot's stored memory. It's very much like SpaceChem and similar logic/programming puzzle games, only in this little game, you'll be using math more than you'd expect!

Don't be replaced by a robot! Just learn to program robots! Then send them on tasks involving crates, bombs, explosions and junk food in this free logic/programming puzzle game. Pragmatica is a smart game in the vein of SpaceChem and The Codex of Alchemical Engineering.

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.

Have you ever wanted to run your very own tile factory? Of course you have. But manual labour is so yesterday; these days we use electronic tiles to program our conveyor belts and other machinery into delivering our orders safely to their goals! All you have to do is puzzle out what goes where in this simple but tricky game that placed second overall in 2010's Casual Gameplay Design Competition #8.

These robots are obviously in peril! Could you imagine using anything other than extreme logic (or Binary Laser Grenades) to save them? Save My Robots is a turn-based programming game similar to Codex of Alchemical Engineering or, more precisely, Junkbot. The goal is to move all 'bots on the screen to the green "X" marks so they can be teleported out. Machines follow the code you've created at the bottom of the screen. All you have to do is program them to make it to their destination. Totally easy to do, right? Right?!

Give your circuits a workout in this deceptively simple puzzle game of logic that puts you in control of building a machine designed to test robots for defects. Defects like homicidal tendencies. You know, the usual stuff. When you're done, make use of the level editor, because the best way to show you care for someone is to tie their brain into knots.

Zachtronics Industries has come up with a new "Game for Engineers", and given its central concept you'd think playing it would blow up the space-time continuum. It's a computer game about programming computer chips. Though it may take some time to grasp its central concepts, Kohctpyktop: Engineer of the People is a rich and rewarding puzzle game.

Yes, that's exactly what cerebral puzzler The Codex of Alchemical Engineering needed. A longer title. Anyway, there are fifteen new brain-teasers here, created by both the author of the original game and its fans. When Zach (the author) says that this expansion may destroy the minds of those who haven't finished the first game, do not take his words lightly.

The latest brilliant-yet-simple logic puzzle game to hit the Web goes by the intriguing title of The Codex of Alchemical Engineering. Called a "game for engineers" by its creator, your goal is to build machines out of mechanical arms that move and transform basic elements to create compounds required to pass each level. It's a cerebral puzzle game that tasks you with arranging and tweaking objects on both a small and grand scale, the final result of which is a burst of euphoric gaming bliss.
