Phantom Rummy is a version of Mahjong, with some elements from Western Rummy card games. Players try to form hands of a pair and two three-card sets to go out. Different hands score different points and whoever has the most points after six or eight hands wins the game.The advanced rules add 'conditions' to certain cards. These conditions award players extra points, if the condition is met (for example, player has cards numbered 1 or 7 in his hand). - BoardGameGeek
