Ben Affleck Banned from Blackjack at Vegas Hotel

Is Ben Affleck a little too good at cards?

The Oscar-winning actor/director was banned from playing blackjack at the Hard Rock Casino & Hotel in Las Vegas Tuesday, after it was deemed that he "was too good" by security, a source tells ET.

"The security said, 'We have to stop you because you're too good,'" the source said.

Affleck, 41, was only banned from blackjack, and was welcome to play other games.

"The hotel was really nice," the source added. "They told him he could play other games and ended up getting him and Jennifer [Garner] a car back to their hotel."

Hard Rock Casino & Hotel commented on the report Friday.
