There is a mode where you can build your own city. There is an arcade mode where you can build an endless tower. There is a leaderboard.
You need to choose which block you want to build a building from, and then your task will be to build an even building from that block. During the construction, make sure that the blocks do not fall to the ground, as your goal is to build the tallest building possible to accommodate as many people as possible. After construction, you will need to select the location where you want to place the building, and then the game will be saved.
