Idle Master - Get your Steam Trading Cards the Easy Way

I created an application that automatically idles your Steam games to extract all of your available Steam Trading Cards. The application automatically finds the games you have drops remaining in, and idles those games one by one until all of your trading cards are in your inventory. This way, you can start up the program and go to sleep / work / away and come back to an inventory full of cards.

Installation Instructions

Go to the Official Site, download and run the setup.exe file there. The program should launch automatically when the installation is complete. Make sure Steam is open and you're logged in. To start idling, you'll need to click the (Sign In) button and sign in to Steam. Once that's done you should be "in-game" on Steam and the program will indicate as such. Now go watch TV, go to bed, or go on vacation. When you come back to your computer, you should have a pile of Trading Cards in your inventory.

Some FAQ

How does this work?

First of all, the program will determine which of your games still have card drops remaining. It will go through each application and simulate you being “in-game” so that cards will drop. It will check periodically to see if the game you’re idling has card drops remaining. When only one drop remains, it will start checking more frequently. When the game you’re idling has no more cards, it’ll move on to the next game. When no more cards are available, the program will exit.

Do I need to download a game in order for this program to get it's trading cards?

No.

Do I need to be logged in to Steam for Idle Master to work?

Yes, Steam needs to be running and you must be logged in.

Can I play a game while this is running?

It’s possible, but doing so may significantly reduce your card drop rate. For best results, exit this program before playing a game.

How do I close the application?

Simply click the red X on the application.

Is this safe?

Presumably so, yes. The program that simulates you being in-game is no different than other popular methods like using Steam Achievement Manager or "the AppID trick".

Why do I need to sign in to Steam from the application?

When you visit your badges page on Steam, it will show you how many card drops you have remaining in each game. When another user looks at your badges page, they can only see the badges you've completed. By signing in, this allows Idle Master to connect to Steam properly and gives it access to this information that only you can see.

Why should I trust this?

The entire project is open source, which includes the source code for all binaries.

Troubleshooting

Idle Master looks like it's working, but I'm not getting any Steam Trading Cards.

First of all, be patient. Idle Master doesn't make them drop any faster than they normally would if you were playing the game, and each game has a different drop rate. Another thing to check is that your Steam profile correctly shows that you're "In-Game". If Steam doesn't think you're "In-Game", it means something is wrong with your configuration.
