I have a second generation I Pod touch. How do I know which games I can download from the Apple Store?

Hello, Suzanne.

Thank you for visiting Apple Support Communities.

Unfortunately there isn't a list available at this time for applications that are specific for your iOS/Software version. However, once you know which iOS/Software version you have installed, you can browser various applications and look for ones that meet your system requirements. I have included a screenshot below on how to look for this information.
