Before the tiles are shuffled and the wall is built, each player sits down arbitrarily at the table. Set aside one of each wind tile, an even, and an odd numbered tile. Shuffle the wind tiles face down and arranged them sandwiched in between the odd and even tile.
A player rolls two dice and counts off, starting with himself as one, the next player as two, etc. continuing counterclockwise. The indicated player, then rolls the dice once more noting both the total and if the total is an even or odd number. This will determine who draws first and from which side. Again, he counts off starting with himself. 1Bam South North East West 2Bam Wind tiles face up for illustration purposes
If the number is odd, for example, the indicated player draws the face down wind tile closest to the odd-numbered tile (in this case South). The next player in turn draws the next wind tile (North), and so on (East and last West). The wind tile drawn is your seat wind. The player who is east remains stationary while the other players arranges themselves accordingly. Shuffle up all of tiles and build the wall.
Playing order: East, South, West, North Winds
Seat winds are winds assigned to each player hand1.png The player sitting at the star is East in the first hand
If the deal passes when the hand is over the playerâ€™s wind change. The player who was originally East position is now North, the player starting as South is now East, etc. In other words, the winds rotate counterclockwise. hand2.png The player sitting at the star is now South
When the player who was originally East becomes East again (deals again) a new round begins.
Each round is assigned a wind, known as the prevalent wind or round wind. After each round the prevalent wind changes. For the first round the prevalent wind is East, for the second South, third West, and fourth North. A marker or indicator is commonly used to keep track of the round. Dealing
Tiles are then dealt accordingly to each player. The wall will be 17 tiles in length. The last 14 tiles are set aside as the dead wall. Dora Indicator
The third tile from the end of the dead wall is turned face up. This tile indicates which tile is dora.
The object of the game is to complete a hand before anyone else. A completed hand consists of 14 tiles, which in most cases arrange themselves into 4 x sets of 3, and a pair although there are exceptions such as 7 x pairs. The number of points â€” not the number of completed hands â€” at the end of the game determines the winner.
During the game a player may ”open his hand” by claiming a tile from another player to complete any one of the following sets:
Chi: Claimed from the player to your left or for mahjong.
Pon: Claimed from any player.
Kan: Claimed from any player. A replacement tile is drawn afterwards. Another tile in the dead wall if turned face up to reveal the kan dora.
Concealed and Small Melded Kong: Announced only after drawing a tile from the wall (i.e. not after claiming a tile). A replacement tile is drawn afterwards from the back end of the wall. Another tile in the dead wall is turned face up to reveal the kan dora.
Arrangement of Tiles
Discards are placed rows of six in front of the respective players’ wall
Tiles claimed are rotated 90 degrees within the set to show which player had discarded it.
Concealed kongs have two outer tiles face up and two tiles face down. This is the distinguish concealed and exposed kongs when scoring. Post Hand
The dealer wins the current hand or earns points for tenpai (one tile away from a complete hand) he/she deals again, retaining the East position, otherwise the deal passes. The hand ends in draw the deal passes to the player to the right. A round is over when all players get a chance to deal.
If a draw occurs any player who is tenpai can show their hand. Players who are noten (not one tile away from winning) have to pay a total of 3000 points to players who are tenpai. For example, Player A is in tenpai whereas B, C, and D are not, Player A receives 1000 from each player. A 100-point counter is placed to the dealer’s right-hand side.
An abortive draw may occur under these four conditions:
Nobody wins after four kans are declared. All four of the same wind tile is discarded within the first go around. A player has nine different terminal and honor tiles within the first uninterrupted go around. Four player’s declare riichi. Hands are shown if nobody can win on the last discard.
Under these conditions the noten penalty is not applied. A 100-point counter is placed to the dealer’s right-hand side.
A counter is placed on the dealer’s right-hand side after a draw or after East wins. Each counter increases the payout to the winner by 300 points. In case of a self-drawn win each opponent plays 100 for reach counter. Counters are removed when another player declares a win. When there are five or more counters on the table a minimum of two yaku are need to win. If the deal passes the previous dealer’s counters are returned and the new dealer replaces the counters with the appropriate amount.
Riichi bets are collected by the winner. Should a draw occur the riichi bets remain on the table.
After the round is over the prevalent wind changes. The order of the winds are East and South.
The player with the most points at the end of the game wins. Uma
At the end of the game a scoring adjustment is made to reward the top players and punish the losing players. Rank Adjustment 1 + 9000 2 + 3000 3 – 3000 4 – 9000
A minimum of one yaku is needed to call for mahjong. Emphasis is placed on concealed hands. After winning add up all the minipoints and yaku then convert the values using the charts below.
As these rules are based on tournament play there are no initial starting points. If you are playing casually everyone can start arbitrarily with 25000 points.
A minimum of one yaku is needed before going out. When there are five counters out (due to Dealer’s consecutive wins or draws) a minimum of two yaku are needed to go out. Dora and red five tiles do not count towards the yaku minimum. The dealer usually pays more upon losing but on the same token receives more when winning.
Win by a discarded tile: Discarder pays winner full score plus values for other players as well. Win by self-drawn tile: All player’s pay the value of the winner’s hand.
If you have less than five yaku in your hand you must add up any mini points and follow the values based on the charts below. The minipoints (fu) are then rounded up to the nearest multiple of 10. If you have five or more yaku in your hand you must use the limit hands chart below.
The winner of the hand will also collect any riichi bets on the table. If there is more than one winner, the player closest to the discard collects the riichi bets.

A chombo is a severe penalty. The offender pays 4000 to East and 2000 to others. If East is the offended he pays 4000 to each. Chombo penalty occurs under these circumstances:
Invalid declaration of a win Declaring riichi on a hand that is not waiting (determined in case of a draw) Declaring a concealed kan after declaring riichi (determined in case of a drawn or the player wins) Exposing five or more tiles from the wall, the player’s hand or opponent’s hand. Claiming a tile after a dead hand.
After a chombo, riichi bets during that hand are returned and there is a re-deal. No counter is placed and the deal does not rotate.
Late to Game
If a player is late by < 10 minutes the player is penalized 10 points; 11-15 minutes the player is penalized 20 points; after 15 minutes the player has forfeited the game.
If a player makes an error in making a chi, pon, or kan, and fails to correct the error, he forfeits the right to win the current hand.
Calling a tile. A player will be penalized 10000 points second or 20000 points third time during a session.
Touching a Tile
If a tile is touched from the wrong side of the wall and was revealed or touched the image surface the player forfeits the the right to win the current hand. The tile is returned. Exposing tiles from an opponent’s hand or from the dead wall results in a dead hand.
Wrong Tile Count
A player with more than 13 or fewer than 13 tiles forfeits the right to win the current hand. A player who does not take a replacement tile after a kan before discarding has a dead hand.
