Ben Affleck has reportedly been banned from playing blackjack at a Las Vegas casino, a source close to the Oscar-winner has said.
Affleck, 41, was stopped earlier this week by security guards at the Hard Rock Casino in Las Vegas while playing blackjack, where he was told "you are too good," the source said.
Mr Affleck was permitted to stay and play other games, the source claimed.
An earlier story by celebrity news outlet TMZ.com said Affleck had been banned for life from the casino for counting cards, a method of using probability to predict the next hand.
But the Hard Rock Hotel & Casino disputed claims he has been banned from the venue in a statement, Fox News has reported.
"Mr. Affleck, a valued guest of Hard Rock Hotel & Casino, is not banned from our property and is welcome back any time," it said.
Counting cards is not technically illegal, but is heavily frowned upon by casinos.
The actor, who won Oscars for co-writing 1997's Good Will Hunting and producing 2012's Argo, recently starred in last year's crime thriller Runner Runner, where he played an online gambling tycoon.
Affleck was on a short break in Las Vegas with his wife Jennifer Garner before he left to shoot Zack Snyder's upcoming "Man of Steel" sequel where he will play Batman opposite Henry Cavill's Superman.
