Zookeeper DX is priced at $0.99 in Google Play. It is normally priced at $0.99 in the Amazon Appstore. As we've noted before, there are sometimes differences in pricing and availability between the two marketplaces.
Zookeeper DX is described as follows:
[How to play]Zookeeper DX is rated at 4.2 stars in Google Play, and has 4.0 stars in the Amazon Appstore.
A puzzle game with simple rules - clear out panels by lining up more than three equivalent by swapping two neighboring panels.
Touch and drag the animal to the direction you want to insert, and the animals switch positions. Vertically or horizontally, line up more than three same animals to catch them. Catch more than target number, and you beat the stage.
NORMAL GAME:Advances to next stage if you catch more animals than target.
TOKOTON:Catch 100 animals and advance to next stage! Devoted mode without stage limit.
There is also a version in the iOS App Store. It is priced at $0.99, and is ranked at 3.5 stars for both current and overall ratings.
We continue to be disappointed with the FAOTD program. It began promisingly enough, with Angry Birds Rio, but we've gotten tired of the endless games or niche apps, and especially apps which have no uptake in Google Play, and seem to be FAOTD as a desperation move by the developer.
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.
