There is no definitive answer to this question since the amount of money that someone has won in roulette can vary greatly depending on the game and table that they are playing at. However, some of the most significant sums of money that have been won in roulette include $38 million (£24.5 million) on a single spin at the Monte Carlo Casino in Monaco, and $32.5 million (£21.
4 million) on a single spin at the Caesars Palace Resort and Casino in Las Vegas. It is also worth noting that the record for the most money won in a single session of roulette is currently held by British player Gary Boyd Roberts, who pocketed £9.2 million (US$14.8 million) during a session at the Genting Grand Prix casino in Kuala Lumpur in 2009.
