If you really wanna see Rock gamble, you need to see "The Vegas Casino War"!

"In his final film performance, Rock Hudson stars in The Vegas Casino War, a spellbinding drama that tells the story of Neil Chaine (Hudson), a charming co-owner of a casino who is double-crossed by his partners and left high and dry. But rather than suffer the agony of defeat, Chaine gets his revenge by turning a run-down building, located right across the street from his ex-partners, into Las Vegas' leading attraction."

I think it's also called The Las Vegas Strip War. The first casino...the one he's partners in, is the Desert Inn. The "run down building" is the Tropicana ! There's some good shots of both of them. And, in the end, Rock goes to the craps table at the DI, with a case full of money...and challenges them to raise the table limit...
