 SpaceChem was ported to the iPad in October 2011, using touch controls instead of mouse and keyboard to manipulate the visual program. An Android port was released in July 2012. Both mobile platforms include most of the full game excluding the defense puzzles. The sandbox mode was added at the request of a player who was trying to explore SpaceChem computational abilities. Alongside the sandbox mode, Zactronics offered a contest for the most interesting sandbox creation. This same user was able to demonstrate a brainfuck interpreter within SpaceChem, claiming that the visual programming language was Turing complete. Barth has mentioned the possibility of a sequel in an interview with IndieGamer.
