Trainyard is $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.
Trainyard is described as follows:
Trainyard is a puzzle solving game unlike any that you've ever played. It's easy to learn but very tough to master. Your job is simple: get each train to a goal station. Red trains go to red stations, blue trains go to blue stations, etc. You control the trains by drawing track for them to follow. There isn't a time limit or even a score; the only thing you need to do is figure out a solution for each puzzle.Trainyard is rated at 4.9 stars in Google Play, and has 3.5 stars in the Amazon Appstore.
The first few puzzles are almost too easy, but as the difficulty increases you'll be thankful that you were able to practice the fundamentals of drawing track. As the game progresses, you'll have to use colour theory to combine trains of different colours, use timing to merge and split trains, and use every inch of your brain in your quest to beat the game.

To be clear, that 4.9-star rating in Google Play comes with nearly 1,000 overall. With these ratings, we'd say "buy" this app while it is free.
There is also a version of the app in the iOS App Store. There it is $2.99 and has 5 stars for both the current and overall ratings.
The app also has a version in the App Store. There, it is $0.99, but has a number of in-app purchases. There is no rating for the current version, but overall, it has 4 stars.
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.
