Virtual City Playground: Building Tycoon is a free building simulator game. It lets you build your own city from scratch.
You start off with a small plot of land. You can build houses, factories, garages, shops, offices, and other buildings. You can also transport your citizens to parks, cinemas, and stadiums.
As you expand, you’ll have more room to build, and you can build more than one factory.
If you manage to collect enough coins, you’ll be able to unlock the ability to build more than one factory, as well as an airport, a stadium, an apartment tower, a skyscraper, and even an ice castle.
