What freeware games/applications are available for a Blackjack II running Windows Mobile 6.1?

I would like to download some games (specifically mahjong!) for my Blackjack and also was curious what other types of freeware is available. I know Windows is very unforgiving, but I was hoping someone knew of something out there!
I have successfully used site run applications like Google Maps, Youtube, and Facebook, but have had a much more difficult time finding other free and reliable .CAB options.
TIA!
