Ben Affleck has been banned from blackjack for life at the Hard Rock casino in Las Vegas after security claimed they caught him counting cards.

Though counting cards isn't technically illegal, it gives players an advantage by decreasing risk. The practice can, and did, get a player kicked out of a casino. Security reportedly called a car to take Affleck, who once won $800,000 in a blackjack game at Hard Rock in 2001, back to his hotel room.

According to CNN, one source says security asked the actor to leave after telling him, "You are too good at the game."

Affleck is said to have been in Sin City with wife, Jennifer Garner, for a quick getaway before filming for the newest installment of 'Batman' begins.
