It's that time of the year again: the Steam Summer Sale is here! Get SpaceChem or the entire Zachtronics Puzzle Pack for a very affordable price! :) In addition to SpaceChem the Puzzle Pack contains Infinifactory, TIS-100 and Shenzhen I/O. I'm especially fond of Infinifactory, it's kind of like SpaceChem but in 3D -- and initially I thought, too, that it sounds like a bad idea, but it actually works really well. :)

Redditors have finished a massive undertaking finding the best solutions to all of the main game puzzles! The archive is at https://www.reddit.com/r/spacechem/wiki/index and also contains solutions to ResearchNet puzzles. There are, of course, different solutions for minimum cycles and minimum symbols where those solutions differ from each other. Great job!

Steam user gggol is hosting the 2017 SpaceChem Tournament! Starting from June 1, 2017, there will be ten different puzzles and two weeks to solve each of them. The full rules are available in the relevant Steam Community discussion thread.

Zachtronics recently released a new game called Shenzhen I/O! Check out its Steam page and the new Shenzhen I/O Wiki!
