First, you need to make sure your Animation Throwdown game is linked to your Kongerate account. If it's not, go to your main screen and click the icon with a K in the red box. Then either create or login to your Kongregate account and link it to your Steam account.

This is very simple. A lot of people probably already know this, but this guide is for people that never played the game outside of steam. So here is the deal, Steam does not have any Ads built into the system, which is why it is a VIP feature. Normally, this chamber is supposed to be free, but you must watch an AD before using it, so long story short, just use your Android or iPhone just to use that chamber, then you can log back in on Steam and see there is a card being processed.

If you don't have an Android or iOS avaliable, there are still ways to do this.

Another option is to download a computer program called BlueStacks. BlueStacks is a Android emulator for your PC, which will allow you to download and use the Android version of Animation Throwdown. BlueStacks Android Emulator[www.bluestacks.com]

The easiest alternative option is to launch Animation Throwdown from Kongregate's website. The only problem with this option is Kongregate's website doesn't have any Ads avaliable alot of the time, meaning you can't use the chamber if they don't have ads.
