Hi, we meet again. Hence, which team won the Amazing Race this season? Was it Dave & Conner, father-son, parent-child team? Let's see the verdict.

Leg 12 (United Kingdom → United States)
Airdate: May 18, 2014

•  London (London Heathrow Airport) to Las Vegas, Nevada, USA  (McCarran International Airport)
• North Las Vegas (Desert)
• Las Vegas (MGM Grand Las Vegas) 
• Las Vegas (Neon Museum Boneyard)
• Las Vegas (The Mirage)
• Henderson (Maverick Helicopters) 
• Las Vegas (Las Vegas Motor Speedway) 

In the first Roadblock of the Leg, one team member participated in an illusion with magician David Copperfield. After opening up the box they previously dug up from the desert, retrieving the keys inside, the team member performing the Roadblock was shackled to the inside of a box and once the box was closed, their partner would hand over the keys through a hole in the box. Copperfield then escorted the teammate sitting out the Roadblock to a television monitor to watch their partner attempt the challenge. After the team member inside the box found the right key and unlocked the shackles, they had to retrieve lockpicks from the top of the box, after which the box was lifted off of the ground and lit on fire. Once the racer in the box said that they were complete, the partner, under Copperfield's instruction, set off a series of switches that dropped the box into a burning pile of wood and set off a fiery explosion. Copperfield then informed the partner that they would have to get the fire department's assistance, and the racer in the box would appear wearing a firefighter uniform, completely unharmed. Copperfield would then give them their next clue, after a bit of sleight of hand. In the second Roadblock, the team member who sat out the first Roadblock had to get in a helicopter, wearing a special futuristic jumpsuit, and then search the Las Vegas Strip for a sign (at the Aria Resort and Casino) that told them the name of their drop zone and location of the Finish Line: the Las Vegas Motor Speedway. After informing their pilot, they then did a tandem 10,000-foot (3,000 m) freefall into the race track's infield, spewing fireworks along the way, and joined their partner before crossing the Finish Line.

Additional tasks

• After landing in Las Vegas, teams were chauffeured by a driver in one of three Ford Explorers to an isolated location in the desert. Upon arriving, the chauffeurs simply told the teams to get out of the car and dig. Teams eventually unearthed a box that said "Property of David Copperfield". After retrieving the box, they returned to the car and were driven to the MGM Grand.
• The clue retrieved from the Neon Museum's "bone yard" instructed teams to take a light bulb from a silver and red question mark sign and take it with them to The Mirage.
• At The Mirage, teams were hoisted on a window washing scaffold to one of the hotel's signs atop the tower, where they had to replace all of the light bulbs in the sign's letter "I". Once they replaced all of the bulbs, they had to tell the employees how many bulbs they used (241) in order to receive their next clue.
