We have to preface the answer to this question by stating that there have been many big winners at our US casinos since 2003, and we have highlighted them on our site. Furthermore, most online casinos for US players have a listing of all the latest winners including the slots played. According to Las Vegas statistics, a young man from Los Angeles won the $38.7 million dollar jackpot in 2003. He only put 3 one dollar coins at the Excalibur Hotel & Casino, and hit the progressive Megabucks jackpot. An interesting note to this win is that like all progressive jackpot machines, this slot was linked to 157 other slot machines in Nevada. Also, according to winning stats, the previous record was $34.9 million that was won in 2000 at the Desert Inn in Las Vegas. Finally, because the jackpot had been steadily growing since 2002, a woman at Bally’s Hotel in Las Vegas won a whopping $22.6 million dollars.
