Idle Construction 3D

"Idle Construction 3D" is a dynamic construction simulator where you build the world’s most iconic buildings and create an empire of global landmarks. The Eiffel Tower, the Taj Mahal, Big Ben, the Leaning Tower of Pisa, the Burj Al Arab, the Sydney Opera House, and dozens more—you’ll build a total of 20 iconic structures from around the world. The builders work independently: they pick up bricks, carry them to the right spot, and the truck automatically pulls up and unloads the building materials. All you have to do is manage your team effectively, invest in the right upgrades, and watch the building rise floor by floor. When construction at a location is complete, the game shows the finished building from all angles, and all hired employees move with you to the next site. Completed buildings generate passive rental income; collect it and reinvest it in development. The further you progress, the more expensive upgrades become, so you need to invest your money wisely.

How to play?

Hire workers and train them—this increases construction speed and income. If you want to speed up the process, click anywhere near the workers and they’ll start moving faster. Invest in worker speed, passive income, and hiring additional builders. You’ll receive extra money for every level you complete. Add decorations to buildings to make them look more impressive, and learn interesting facts about every structure in your empire. Sometimes a concrete mixer truck pulls up to the construction site offering extra money for watching an ad—you can accept or decline. Short ads also offer super bonuses in the form of extra funds, worker speed-ups, and the ability to summon a super builder, who drastically accelerates the construction pace. Spin the wheel of fortune to get free rewards and use bonuses at the right moment to finish particularly expensive projects faster.
