Link -This app is $2.99 on the Google Play store, I’m not sure how long it will be free on Amazon. If you don’t have the Amazon.com android store installed you can install it here.

The 247 Mahjong game is also free, today only. You also get a free $1 Amazon mp3 credit for downloading this app if you didn’t get that credit yet.
While you’re in the Appstore check out the Free Stuff Times app
