The second in the Blox 3D series, this is also an easy to use, powerful-feeling block building experience. Just keep in mind that your "world" is limited to one screen that is about 60 by 60 by 60 blocks.

You start with an empty screen surrounded with 16 types of building blocks, a simple color palette and 10 moving items.

After a short tutorial that can be skipped, you tap the screen to add a block. A fast double tap takes it away, so you quickly learn that it is possible to unbuild as quickly as you can build.

This version contains more animated city themed features, including cars, planes, helicopters, roads and people. The people walk into buildings, cops chase robbers and trains chug through the city. There are also several types of boats and planes. It is possible to share your city levels with other players using fictional screen names. We liked how you can control the weather and lighting with night,day and rain controls.

It is easy to zoom in or out, or rotate the stage to view your creation from any angle, but we noticed that larger projects result in sluggish navigation. This is a minor issue. We'd only recommend using this app on larger screens. Work can be saved at any point. All things considered, this app is well worth the download. Made in Unity.
