Crazy Formula is priced at $0.99 in Google Play; 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.
Crazy Formula is described as follows:
Ever thought of becoming a famous scientist? We have got the perfect formula for you to start with!
The science here is for you to crack a way to make the formula (fluid) pass through all the lab tubes, till it gets to its final destination, the formulas recipient. For that, you must align all lab tubes in the correct position (so the fluid can flow to the right side of the screen), and you can also mix two or more formulas (fluid), and transform its color or effect (delay etc.).
This truly addicting puzzle/board game will train your scientist mind, and leave you intrigued.
Can you puzzle this out?
- 135 progressive and challenging levels
- 15 formula books
- Tutorials in the key levels
- Intuitive game play: drag tubes, mixing colors, delay flow, change colors
- Original graphics and sounds
Crazy Formula has a 4.0-star rating in Google Play; it has a 4.1-star rating in the Amazon Appstore.
"Buy" this one while it is free. The game must be superb if reviewers aren't complaining about in-app purchases on a paid game, something that usually draws fire at Amazon.com.
There is also a version in the iOS App Store. There, it is priced at $0.99 and has 4.5 stars for the current version and 4.0-stars overall.
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."
