SpaceChem shirts can still be purchased here!

The Zachtronics Store is Closed

Over the past few years, both independent games and digital distribution have grown tremendously. One of the benefits of this is that we are no longer required to operate our own store in order to sell our games, and so we are closing the Zachtronics Store.

New Customers

If you'd like to purchase SpaceChem, the best place to buy it is probably Steam. The Steam version of the game includes exclusive features like friend leaderboards and bonus TF2-themed puzzles.

For a DRM-free version of the game, check out GOG.
