The game can be interrupted by four events. They are the following:
Flower or Season
The last tile of the wall is drawn as a replacement tile whenever a player draws a flower or season, ensuring that they have the 14 pieces required before their discard.
Melding Another Player’s Discard
Other players may take a tile that has been discarded by one player to finish a meld. The advantages of stealing tiles include constructing a winning hand more quickly and earning extra points. At the same time, the drawbacks include having to expose a portion of one's hand to other players and being unable to alter a declared meld.
Moreover, the player must specify the type of meld to be proclaimed when declaring it through a discard before exposing the meld by setting the three or four face-up tiles.
Winning A Hand
Play is stopped when a hand is won in order to evaluate the hand's viability. Following confirmation, the player receives the hand's worth in accordance with the rules of the particular game.
Winning a Hand From a Discard
A player declares victory and reveals their winning hand if, at any time throughout the game, they can utilize another player's discard to finish a legal hand. The hand is over at this point, and mahjong scoring starts.
Based on established table rules, there are several methods to handle the scenario if more than one player can utilize a discard to win the hand. The winner may be determined by adding up the points each player would have gained from the discard, selecting the person who is closest to the discarder in turn order, or concurrently awarding wins to many players.
Winning a Hand From the Wall
A player can also succeed by drawing a tile that finishes a valid hand. This can also be referred to as winning from the wall. Winning from the wall in Hong Kong Mahjong doubles the basic points that each loser must pay.
Winning a Hand By False Win
The declaring of a winning hand is technically permissible at any time. The player must have a full and legitimate hand, though. If not, the player is punished.
- The punishment is based on the table rules.
- The player can hand the other players their points back.
- The player who announces the fake win is also subject to a potential punishment of having to play the remainder of the hand with their tiles face up.
- Some strategies impose punishment at the conclusion of the whole contest.
Robbing a Kong
A play known as robbing the kong is an uncommon yet high-scoring element of Hong Kong mahjong. If a player attempts to declare a kong by adding a fourth piece to a melded pong, but another player can use that piece to finish the hand, the winning player has precedence and may remove that piece from the person who was attempting to declare the kong.
