PLEASE NOTE: An internet connection is required to play this game!
PLEASE NOTE: This app lets you purchase digital content using actual money. You can configure parental controls for in-app purchases, which will require your Amazon account password or a 4-digit PIN, by going to the Settings menu from within the Amazon Appstore.
The low rating in the Amazon Appstore is because the app is paid, but has in-app purchases. We'd pass, personally.
There is also a version of the app in the iOS App Store. There, the app is free, but has a number of in-app purchases. It has 4.5 stars overall and for the current version.
We'd like to see free versions of say, Office-compatible software or useful utilities such as CalenGoo instead of niche apps or endless games (we just assume every day that it's going to be a game; it's gotten that bad).
Amazon.com opened up the Appstore despite a lawsuit by Apple, which has previously trademarked the term "App Store." Microsoft has filed an appeal against that trademark, saying the term is too generic. Amazon.com has responded to the lawsuit in the same manner.
