Percy, Annabeth, and Grover leave the truck and walk the streets of Las Vegas. They arrive at a dead end where a doorman at the Lotus Hotel and Casino kindly invites them in. Inside they are blown away by what they see: a huge lobby/game room with every kind of game and every kind of snack you can imagine.

Las Vegas was first reported as the location for the 25th season by the website Vevmo on September 8, 2010. Pre-production started in August 2010, and filming took place from October to December 2010 at the Hard Rock Hotel and Casino. The season premiered on March 9, 2011, consisting of 13 episodes.
