What is this movie title?

There is this movie that I watched about 2 years ago,but I forgot the title of it.The movie was about cards and how to cheat in poker I think.It had like 3 hot main characters who were girls.I remember seeing the word spade/spades in the title but I'm not sure.These girls go to vegas or something to gamble and they're really good at it so they keep doing it until they get caught and become all greedy with the money that they won so basically they backstbbed each other in the end.Something like that.Does anyone know the title of it?
