Ben Affleck knows how he wants to spend his weekend and it's not on the movie set of Live By Night! The first chance he gets, enjoys a post-filming cigarette and hops a private jet provided by the Sands Casino, on his way to Vegas, baby!

The notoriously-successful blackjack player was banned from the Hard Rock Casino in Las Vegas back in 2014 for card counting -- which is NOT illegal, by the way. Basically, he was winning too much money so the pit bosses wanted him OUT. Well, apparently The Sands wants him! The company owns the Palazzo, The Venetian and the old-school Sands, some of Vegas' top casinos and certainly hot spots for high rollers like Ben.

Enjoy the weekend getaway, Ben! Hope you make good $$$!
