Submachine (meaning "submerged machines") is a point and click, "escape from the room" puzzle game where the player must find objects and clues scattered throughout a few rooms, figure out what to do with them, and apply them to certain objects and circumstances to open up more areas and to hopefully beat the game.

Basically all the player (who is never shown) has to do is use the mouse to search for onscreen items and clues and click on them in order to place them somewhere or store them into their inventory for later use, or to press a button or move a lever, switch, or other device to perform a function that will help solve the mysteries of the game.

At first glance, this just seems to be a simple "escape from the room" (or area, rather) game with only a few objects to gather and figure out how to escape, although there is a diary page that is found that tells of a bizarre story in regards to someone losing one of their arms in an accident, but then they were somehow able to grow an invisible, third "karma arm" that could manipulate time and space.

As far as the original Submachine game went, it had only a few rooms and objects that would open up a few things to lead to the player's escape. The object of the game was to find four gray tiles and put them in their proper place, which would lead to an elevator that would allow the player to escape from wherever it was that they were trapped. Other than the "bell puzzle", where the player needed to ring four bells in a certain order to reveal a tile piece, the game could be solved with using just a few everyday objects.

However, once that game was initially released (and well-received), people asked for it to be a little longer, so creator Mateusz Skutnik made the first (of a few) Extended Version of it.

Differences from the original Submachine[]

  • There are several more rooms.
  • There are several more puzzles.
  • There is one secret, which leads to an Ancient Crystal of Wisdom, which wasn’t in the original game.
  • Several objects (the clock) have been moved to different positions.
  • The date on the coin is random; originally its date was fixed.
  • Some objects are now in different areas (i. e. the valve now goes in a different room, although it still has the same function).
  • A tile won’t be found when the box is unlocked with the combination device.
  • In the Float version of the game, there are a couple of minor changes in sound, such as there being no dripping sound in the room with the leaky pipe.
  • Also in the Float version, the player automatically walks out when the game is beaten; in the previous versions, the player had to click on the end of the corridor to exit.
  • The radio function changed in the Float version. Originally the player had to keep the cursor on the button so the drawer with the spoon would open, but now the player just has to click on the button and the drawer will open.
  • In the first Extended version, there was one task that, if not performed correctly, the game could not be beaten. This would be changed in later versions.



The original version of the game was just known as Submachine. It would later be renamed as Submachine 1: The Basement.
