Are you ready to take on the challenge of building your own city from scratch? With your trusty truck equipped with a powerful drill, you can mine through different stones of varying difficulties and gather raw materials to construct buildings that will earn you wealth and prestige. You control your own truck and explore different areas to collect raw materials. Every stone area has its own requirements, which you must meet to unlock and access the stones. Once you've gathered enough raw materials, head to the factory and process them to make them more valuable. But your job doesn't end there! You must then deliver these processed materials to different buildings to help construct them. Each building has its own specific stone needs, so it's up to you to fulfill those requirements to start construction. Once all the requirements have been met, you can either sell the building and receive a lump sum or rent it out and collect income over time. To make your job easier, you can upgrade your truck's drill power, speed, and capacity, and even customize it with a fresh coat of paint. You can also hire up to three workers to help you grind stones and deliver materials to the factory. But be careful not to overload your truck, but you can always upgrade your truck’s capacity! In addition, you'll need to build bridges to access new areas and historical landmarks, but the important question is, can you build them all?
