ATLANTIC CITY, N.J. (AP) — A case pitting a casino against gamblers who won $1.5 million in a game with unshuffled card decks may be heading toward trial.

In April 2012, 14 mini-baccarat players racked up the winnings over 41 straight hands when they realized the cards hadn’t been shuffled and were coming out in a specific pattern. Many of them quickly upped their bets from $10 a hand to $5,000.
