This engaging three dimensional simulation lets you operate a tower crane on a construction site. Your goal is to use the magnetic grabber to lift colorful shipping containers and carefully lower them onto the highlighted green landing pad. Control the jib rotation with the left and right buttons or the A and D keys. Move the trolley along the jib using the in and out buttons or the W and S keys. Raise and lower the hook with the hoist up and down buttons or the Q and E keys. Toggle the magnet with the dedicated button or the spacebar to attach the nearest container. Drag the mouse or finger across the screen to orbit the camera freely while tracking your delivery progress through successive levels.
