A Mahjong game is played at a square table (four sides all the same length). The dealer is called the "east" player and everyone else is called a different direction because of where they are sitting - so the person to East's left is South, the person across from East is West, and the person to East's right is North. If East wins, he is the dealer again for the next round; if he does not, the dealer is the person to his right (North). That person then becomes East. A game of Mahjong ends when every player has been the dealer four times, or when they have played the number of rounds they said they would play before they started.
