Mah Jongg is an ancient chinese game usually played by four players, named after the four winds, who take tiles similar to dominos from a wall in turn. THEORY OF PLAY The object of the game is to remove all the tiles from the board. Tiles are removed in by matching two identical tiles which have either an open left edge or open right edge. The only exception to this rule is that any open "flower" tile (bamboo, orchid, plum, or chrysanthemum) matches any other open "flower" tile and any open "season" tile (spring, summer, autumn, or winter) matches any other open "season" tile. xmahjongg version 3 is a complete rewrite by Eddie Kohler of xmahjongg versions 1 and 2 by Jeff S.
