Ashley Revell (born 1971 in Maidstone, Kent) is an English gambler. He sold all his possessions, including his clothes, and gambled US$135,300 on a single spin of a roulette wheel in the Plaza Hotel & Casino, Las Vegas, in 2004. Revell even changed his name by deed poll to "Ashley Blue Square Revell" after the UK online bookmaker contributed to his gambling fund. He raised additional cash through car boot sales and auctions.He has been termed a 'professional gambler', but this is a misnomer. Revell relied purely on luck when he placed a single bet on red. The ball ended up on 7 red and Revell doubled his money to $270,600. Revell used his winnings to set up an online poker company called Poker UTD, which later went out of business in 2012. The event was filmed by Sky One as a reality mini-series titled Double or Nothing. He was also featured in an E! documentary special along with Stu Ungar called THS Investigates: Vegas Winners & Losers. An episode of the TV series Las Vegas entitled "One Nation, Under Surveillance", first broadcast on 14 March 2005, had a character and event loosely based on Revell. Simon Cowell said that Revell's bet was the inspiration behind his new game show called Red or Black?.Revell also owns iGaming Recruitment, a website that matches online gambling companies with job applicants.
