Code Breaker Pro is priced at $2.38 in Google Play; it is normally priced at $1.18 at the Amazon Appstore. As we've noted before, there are sometimes differences in pricing and availability between the two marketplaces.
Code Breaker Pro is described as follows:
Classic Code Breaker game. Can you crack the secret code.
Code Breaker is a classic code breaking game. Can you break the secret code?
You guess the secret code by placing colored peg in a row. After each guess you will get one black peg for each correct colour in the right place and one white peg for each correct colour in the wrong place.
Code Breaker Pro has no ratings -- none -- in Google Play, and has a 3.5-star rating in the Amazon Appstore.
That's good enough for us to say buy it while it's free, since it is free.
It appears there is a Code Breaker app in the iOS App Store, but it doesn't appear related. It is free but doesn't have enough ratings to display.
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.
Apple has already lost a portion of that lawsuit, which said Amazon.com had participated in "false advertising."
