you cannot install apps/games on an SD card, you can install them from the SD card on to the phones memory by downloading the xap file from windowsphone.com and then putting the file on the SD card and then putting it back in your phone and then the SD card will show up in the Store app
You can install apps and game from an SD card, but not to an SD card. It's a frequent complaint about Windows Phone devices, but then again, with slow data transfer rates with SD cards, using apps from one wouldn't be a fun experience anyways.
