Idle Master was writen in C# using Steamworks.NET and CSteamworks by Riley Labrecque ( ), and using open source icons from Open Iconic ( ). Idle Master was created by jshackles, based on the original code created by Stumpokapow. You can also download the source repository above and compile the application using Microsoft Visual Studio. If you are an end user you can download an install Idle Master directly from or by launching setup.exe included in the root of this repository. Non-Windows versions are available in the Python repository but may be depricated or feature incomplete. This program is now being developed exclusively for Microsoft Windows. This application requires Steam to be open and for you to be logged in. When no more cards are available, the program will terminate. When the game you’re idling has no more cards, it’ll move on to the next game. When only one drop remains, it will start checking more frequently.
It will check periodically to see if the game you’re idling has card drops remaining.
This program will determine which of your Steam games still have Steam Trading Card drops remaining, and will go through each application to simulate you being “in-game” so that cards will drop.
