Build a Train is a train simulation application for young children from one to six-years old. I happen to have a few kids at home and tested it out initially with my four-year-old.
The Build a Train game is optimized for children. It has large buttons, bouncy background music and bright, colorful graphics. The child begins the game by choosing their train, cars and map before entering the track. There's a variety of trains that you can build and ten different maps.
Five of the maps are available at the start and the other five can be unlocked by earning points within the game. Additional bonus content like helicopters can also be unlocked. Points are earned
