Leave a mark on the city silhouette with Stack Builder! Times have changed and there are certain trends in architecture now. To keep up with the needs, you have taken a skyscraper project. So, now focus on your work and build up your stack!

You have an excavator at hand and you need to operate it in the best way. You are now solely working on the skyscraper you will be building with that huge machine. You better focus on that single thing, too. Because you have a very vital work at hand, you need to consider even seconds and centimeters. Gently drop each stack that is hanging from the excavator upon the stacks on the ground. If you work well enough, you can go higher and higher. Try to put the stacks on top of each other so as not to let them lose balance until you create a skyscraper!
