Experts said a Las Vegas casino's roulette wheel beat odds of 114 billion to 1 when it hit No. 19 on seven consecutive spins.

Web site Beyond the Best said the phenomenon, which was photographed by visitors to the Rio at 8:32 p.m. Monday, surpassed the 114 billion to 1 odds and the event was made even more unlikely when the streak-breaking number, a 15, was followed by another 19, the Las Vegas Sun reported Wednesday.

Officials with Caesars Entertainment, owner of the casino, said they were unaware of the event. (c) UPI
