Six Dice Yahtzee (Ad Free) isn't available in Google Play, just the ad-supported version; it is normally priced at $0.99 at the Amazon Appstore. As we've noted before, there are sometimes differences in pricing and availability between the two marketplaces.
Six Dice Yahtzee (Ad Free) is described as follows:
Six Dice Yahtzee is a Game Similar to Yahtzee or Yacht, only played with Six Dice instead of
Five. Players have 15 rolls to score as many points as possible.
Also includes "Single Mode", "Double Mode", "Sequential Mode", and "Bonus Roll Mode". Extended Rules Explanation in game.
Also includes Scoreloop for competing online against other players.
Six Dice Yahtzee has a 4.6-star rating in Google Play, and has a 4.6-star rating in the Amazon Appstore.
That is unusual agreement between the two markets, and certainly is good enough for us to say buy it while it's free.
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."
