The Flamingo Casino in Las Vegas just witnessed the biggest Pai Gow Progressive jackpot win in history – a whopping $6,443,401!

The lucky winner, Thomas Z., is rumored to be a poker player from Vegas who just decided to give Pai Gow a try.

According to a dealer, Thomas was so excited when he looked at his cards that he asked, "Is this it?!" And in the spirit of his good fortune, he tipped a generous $65,000.

The table was surrounded by armed security guards, as seen in a photo on a Facebook group.

While we're on the topic of generous tips, it's worth mentioning the time when Bill Gates visited a Las Vegas casino and left a $0.25 tip. This story was shared by a user on reddit who mentioned that their father was a bartender on the strip at the time and was given the small tip by Gates.

While Gates may have been a nice guy, it's safe to say that this particular tip was the subject of much discussion among the staff for a week.

It's always interesting to hear about the unexpected moments that can happen in a casino. Whether it's a massive jackpot win or a small but memorable interaction with a famous face, there's never a dull moment on the strip.

And who knows, maybe the next big tip or jackpot will be yours.

So, how do you hit a jackpot of this magnitude in Pai Gow Poker? To win the progressive jackpot, you need to get a 7-card straight flush, with or without a joker.

There are also smaller payouts for hands like a Royal Flush, Straight Flush, Four of a Kind, and a Full House. Each hand costs at least $5 to play.

In this case, it looks like Thomas hit the jackpot with a straight flush that included a joker. That's one lucky hand!

As for the rest of us, we'll just have to keep trying for that elusive 7-card straight flush. Who knows, maybe we'll be the next big winners at the Flamingo Casino.
