Publisher: Matt Rix-Price:$2.99 (current Christmas sale price-$0.99)- Trainyard is a puzzle app that is set in a “yard” where you have to make trains meet their destination by drawing paths. Each train is a different color, and sometimes the game requires that you merge the two colors to get a different color. There are many different ways to solve each puzzle, and in each province(a group of levels) you unlock a new tool to help you solve this increasingly diffucult puzzles. The great thing about this app is that there is a free version of it with a decent amount of levels and once you finish you can upgrade to the full version. This is app is a good purchase because it presents a unique approach to a puzzle game and allows the user to demo a version before buying the full version. The visuals on this app are decent and make the app look clean and presentable. I would give this app a 9 out of 10. Thumbs. up!
