6. Slotzilla Zip-Line, USA

Inspired by Las Vegas’ slot machines, Slotzilla offers adventurers two choices. The first zip-line starts seven-stories up and sends passengers across two whole city blocks in the standard position. The Zoomline begins 11 stories high, sending you across five city blocks and under the largest LED screen in the world. You’ll soar through SIn City’s light in “superhero” position.
