Hong Kong Mahjong Attache Case

The game is played with a set of 144 tiles based on Chinese characters and symbols, although some regional variations may omit some tiles and/or add unique tiles. In most variations, each player begins by receiving 13 tiles. In turn players draw and discard tiles until they complete a legal hand using the 14th drawn tile to form 4 groups (meld) and a pair (eye). There are fairly standard rules about how a piece is drawn, how a piece is robbed from another player, the use of simples (numbered tiles) and honors (winds and dragons), the kinds of melds allowed, how to deal the tiles and the order of play. Despite these similarities, there are many regional variations to the rules including rather different scoring systems, criteria for legal winning hands and even private table rules which distinguish some variations as notably different styles of mahjong.
