A federal judge has dismissed a lawsuit against Foxwoods Resort Casino by three gamblers who claimed they were denied more than $1.1 million in winnings and lost their $1.6 million deposit because the Connecticut casino wrongly accused them of cheating.

Chinese nationals Cheung Yin Sun of Las Vegas and Long Mei Fang and Zong Yang Li of Los Angeles said they won the money in 2011 playing mini-baccarat. They said they used a legal card-monitoring practice that involves players being able to tell the difference between some cards because of imperfections on their non-playing sides.

The judgment in favor of Foxwoods was entered Monday in federal court in New Haven.

U.S. District Judge Janet Hall ruled the tribe that owns Foxwoods, the Mashantucket Pequots, has sovereign immunity from the lawsuit.
