The goal of this guide
There are many great guides about secrets and hidden glitches on Steam. Most of them use Steam (App ID 753) but can also be used with other App IDs. This guides contains many hidden "games" and to some extend what you can use them for.

This guide on its own is sort of useless. It is only a collection of "special hidden" games on Steam and if you can use them. You will need a separate guide to use them with. Here are a few examples:

https://gtm.you1.cn/sharedfiles/filedetails/?id=270820767 https://gtm.you1.cn/sharedfiles/filedetails/?id=649925765 https://gtm.you1.cn/sharedfiles/filedetails/?id=610115296 https://gtm.you1.cn/sharedfiles/filedetails/?id=617525837 https://gtm.you1.cn/sharedfiles/filedetails/?id=693118839 https://gtm.you1.cn/sharedfiles/filedetails/?id=1809871691

A few notes
  • This guide is only possible because of SteamDB. Please use their site for more detailed information on these apps: https://steamdb.info/
  • This list is created manually and thus entries might have changed significantly or include mistakes.
  • The app name can be ambiguous. In rare cases the name displayed on the store page and in the community hub differ. Some names are based on SteamDB's best guess (e.g. based on depot names.
  • App icons change fairly often and are taken from different sources (header image, icons, banners, etc). Even if a game can be showcased or embed it does not necessarily show this image.
  • Removed or banned games are mostly not included. Please use e.g. steam-tracker[steam-tracker.com] for a full list.
  • A list of apps with Steam inventory items can be found here
  • A more historical list (if not included in SteamDB already) of apps on Steam can be found here: https://developer.valvesoftware.com/wiki/Steam_Application_IDs
  • There's no fixed criteria for apps to be included. If you believe something should be included, just let me know.

Test apps created by Valve employees
These are mostly unusable apps created to test Steamworks or other features for Steam. They were matched based on app and package names, shared (historical) packages, metadata, patterns and other information published online.
Needless to say, these are only best guesses and may not be accurate. It is also reasonable to assume that multiple people were using an app, but aren't listed here.
So these apps were not necessarily created by the listed person, but are at least in some way associated with them.


⠀⠀⠀⠀⋅ Jason Ruymen
Jason Ruymen[www.mobygames.com] is a Valve employee and (in the context of these apps) probably best known for his Steamworks tutorials on the official Steamworks Development YouTube channel, posting removal notifications for banned games and general support for game developers on Steam.

Advertising Apps
Advertising Apps seem to be used for developer/publisher specific sales. Most apps listed here have a public community hub and thus allow you to post there (likely without anyone noticing). This seems unintentional and is perhaps caused by an incorrect configuration (there are also many hidden Advertising Apps).

At the time of writing, none of them can be acquired or included in a profile showcase (except the ones listed in a previous section).
