    Introduce about Billion Builders

    Currently, simulation games are becoming popular. They are the preferred choice for entertainment at idle times. If you’re looking for something new, why don’t you try Billion Builders?

    This creative simulation game was released by Mamboo Games. Here, you will develop territories, in a new world. But, you won’t have to start from the stone age. The first background takes place in the years that steam engines and rail transport are developing actively.

    Build your own city

    In Billion Builders, you can take the train to build your own city. The first thing you need to do is load everything you need into the train. After that, you start the car and move on the road leading to new lands. When the train stops, the workers will get off and begin building your first place. Over time, they will turn the land of the wilderness into bustling and crowded cities.

    Aside from human resources, resources are the most important factor, and you cannot build anything without them. Use the resources available initially to build buildings, residential areas, factories. At the same time, you also need to exploit new types of resources to make the necessary construction materials.

    Idle Supermarket Tycoon has a similar game. But instead of building the beauty of cities, you’ll build supermarket chains and make billionaire dreams come true.

    Expand your city

    At first, your city may seem a little modest. However, when you see the initial changes in a developing city, you will know what you need to do next, to make your city become more bustling.

    Billion Builders is a construction game, but also a large world, stimulating each person’s creativity. You can build many cities, then give them a civilization. And thanks to this factor, Billion Builders becomes more unique than any other construction simulation game.


    During the construction process, you will work with a large number of workers. Therefore, you need to set rules so that they work in the same order and are strictly controlled.

    However, Billion Builders is an idle game, not a rush game. At first, you only had a team of more than 20 workers. After working hard and earning more money, you can hire more workers to increase job performance.

    And as I said, Billion Builders require players to have management ability. You will control many groups of workers, from ordinary builders, engineers, assistants, operators of equipment and vehicles, mechanics. For each group, you will delegate different construction tasks. Build skyscrapers, houses, transportation routes, parks and shopping centers.


    As time went on, the projects grew larger and more complex. Therefore, you need qualified and responsible people, if you want to get the job done with good performance.

    Billion Builders allows you to upgrade three items including Recruit (increase the number of workers), Speed Up (increase work speed), Package (increase productivity). Progress will be motivated when they do move faster, work faster and work harder.

    Build everything you want

    Although included in the category of construction simulation, Billion Builders brings idle gameplay extremely simple. Therefore, you do not have to build a house yourself, just touch the screen to stop the train. The staff team then automatically works and returns to the train when they are finished. In this way, you will see a city built from the first bricks.

    Besides, the construction process can be customized. You can build as much or as little as you want, without obeying any arrangements or requirements from the game.


    There is no doubt about the graphic quality of Billion Builders. The game possesses detailed and sharp 3D images, with bright colors. Besides, the weather and light effects continuously emit when a certain building is completed.
