In all the games you play as an unidentified character who awakes, seemingly after having some sort of amnesia, in new locations of the "Submachine" and have to solve different puzzles and examine the environment in order to escape. The series has been generally well received. There are so far eight installations in the main series as well as four spin-offs. One of the spin-offs was made for a Jayisgames contest and another for the website of the band Future Loop Foundation.
In an interview with Igor Hardy, Mateusz Skutnik stated that "This series should go at least until Submachine 10. After that, I don't know."

The Submachine series has drawn a multitude of fans to join Pastel Forum, created by the developer. On this forum, the fans have developed many theories, which are the main backing of most people's ideas on the story behind the Submachine, due to the often vague storyline that goes along with the series.
Some of these theories were included in one of the newest installations, the Submachine Network Exploration Experience. This was described as a "lovely way to include the player community in [...] a series of solo adventures" by Andrew Plotkin of GamesShelf in his review of the game.
The series has won numerous awards, including four from Jayisgames:
- Best of Casual Gameplay 2007 - Point-and-Click (for Submachine 4)
- Best of Casual Gameplay 2009 - Adventure (for Submachine 6) 
- Best of Casual Gameplay 2010 - Point-and-Click (for Submachine 7)
