Today's Free App of the Day is Final Freeway 2R
A classic road racing game that is well reviewed by Amazon's customers. It does, per the product page, have Open Feint with it, but there are few permissions.
9 of 11 reviews are four stars and above. I picked this up as I think the grandson will like it but I haven't played it yet.
Also, Amazon has some of its Free App of the Day (FAOTD) greatest hits free again today. You can access them by going to the App Store on your Fire and clicking on the banner OR you can click here. It's front and center if browsing on a Fire, but kind of hidden if shopping on your PC or iPad. You have to go to "Shop by Department" and select the App Store link. Or, you can click the previous link. Some really good apps free today!
These apps are compatible with the original Fire and with my Fire HD 8.9" 4G. To tell if an app works for your Fire HD or other Android device registered to your Amazon account, click on the above link and look on the right side of the web page. Amazon will tell you if it will work with your registered device.
