Time to build you tower to the sky! It will take a lot of skill and patience to advance in this game! You need to use your mouse to click on bolts and make your tower as tall as you can. It won’t be easy, and on some levels you might feel like you need an engineering degree to move on, but once you conquer each level, you will feel as though you’ve accomplished something awesome. When you get a great score, share it on the leaderboard and show people what you’ve done!
