A LOT goes through your mind when you’re 168 meters up in the air. It must be more exciting if the city down below is Las Vegas in the US, which has a great night view. Welcome to the world’s largest Ferris wheel, the High Roller. It first opened on March 31. A ride lasts for 30 minutes. You can also enjoy videos and music during the ride. The High Roller stands more than 30 meters taller than the London Eye, the famous Ferris wheel in London, UK.
