The $40 million jackpot won on March 21, 2003 at the Excalibur happens to be the biggest cash jackpot hit so far. The lucky 25-year-old player who won this jackpot desired to remain anonymous, which was a wise decision taken. The player was a software engineer who resided in Los Angeles and he had placed a bet worth $100 on a Megabucks slot. The highest ever bricks and mortar slot machine jackpot awarded to a player was won in the Excalibur Casino in Las Vegas on the 21st of March 2003 and the jackpot won was a mind blowing $39,710,826.36. €17.8 million on Mega Fortune For a long time, the €17.8 million won on NetEnt's riches-themed slot was the largest ever online jackpot. The identity of the winner, a Finnish gambler, is still unknown. $11 million on Mega Moolah.
