1 Mah Jongg is an ancient chinese game usually played by four players, named
2 after the four winds, who take tiles similar to dominos from a wall in turn.
5 The object of the game is to remove all the tiles from the board. Tiles are
6 removed in by matching two identical tiles which have either an open left edge
7 or open right edge. The only exception to this rule is that any open "flower"
8 tile (bamboo, orchid, plum, or chrysanthemum) matches any other open "flower"
9 tile and any open "season" tile (spring, summer, autumn, or winter) matches
10 any other open "season" tile.
