==== Melds ====
'''Melds''' are groups of tiles within the player's hand, consisting of either a pung (three identical tiles), a kong (four identical tiles), a chow (three suited tiles in numerical sequence), or eyes (two identical tiles needed in a winning hand). Melds may be formed by drawing a tile from the wall, or by seizing another player's discard. There are rules governing which player has priority for a discard, and whether the meld should be exposed (displayed to all players) or remain concealed, depending on the manner in which the meld is formed.

| A '''pung''' is a set of three identical tiles. For example:

A pung may be formed with any suited or honors tile. Bonus tiles (flowers or seasons) cannot be used to form a pung because they are set aside and there are not three identical bonus tiles in the set. The tiles must be identical (not of different suits). A pung may either be concealed (formed by drawing tiles) or exposed (formed by seizing another player's discard).

| A '''kong''' is a complete set of four identical tiles. For example:

Consider a kong the same as a pung with an additional tile to make a complete set of four. There are three ways to form a kong.
# ''Concealed kong'' – If a player holds three matching tiles (concealed pung) and upon drawing a tile completes a set of four they may declare a kong. They do so by revealing the meld and placing two pieces in the middle face up and two pieces on the ends face down.
# ''Exposed kong'' – If a player can use a discarded tile to complete three matching tiles (concealed pung) in their hand, they can take the piece and reveal an "exposed kong" or "melded kong". The player reveals their three pieces face up and places the stolen discard on top of the middle tile, or face down next to the three other face up pieces.
# ''Exposed kong from exposed pung'' – If a player already has a melded pung and then later in the game draws the fourth piece from the wall, they may announce (then or later in the game) a kong by placing the fourth tile on top of the middle piece of the melded pung, or all four tiles placed face up in a row. If a pung has been melded a player cannot steal the fourth piece if another player discards it – it must be drawn.

Whenever a kong is formed, that player must draw an extra tile from the end of the wall and then discard a tile. The fourth piece of a kong is not considered one of the 13 tiles a player must always have in their hand. A kong may not be formed from bonus tiles (flowers/seasons), since the set does not include four identical tiles. Kongs are worth collecting to score more points and deprive opponents of the opportunity to obtain specific tiles.

| A '''chow''' is a meld of three suited tiles in sequence. For example:
{{wikitable

|[[File:MJs1-.svg|25px]] || [[File:MJs2-.svg|25px]] || [[File:MJs3-.svg|25px]]
|-
|[[File:MJs3-.svg|25px]] || [[File:MJs4-.svg|25px]] || [[File:MJs5-.svg|25px]]
|-
|[[File:MJs7-.svg|25px]] || [[File:MJs8-.svg|25px]] || [[File:MJs9-.svg|25px]]

The meld must be in absolute numerical sequence and all in the same suit. Players cannot skip numbers or meld from the 8 or 9 to 1 or 2. Honors tiles cannot be used to make chows because they have no numerical value, and bonus tiles (flowers and seasons) also cannot be used to make a chow.

A player can steal a discard to form a chow only from the player whose turn was immediately before theirs; however, a player forming a chow from a seized piece has the lowest priority for that tile. Any other player who needs that tile to make a pung, make a kong, or to win may seize that piece instead. Like the pung, the chow is either concealed (formed by drawing tiles) or exposed (formed by seizing the prior player's discard).

| The '''eyes''' (also known as a pair) are two identical tiles which are an essential part of a legal winning hand. A piece cannot be stolen (melded) to form a pair of eyes unless the player simultaneously completes a legal winning hand.<ref>Lo, Amy (2001). ''The Book of Mahjong: An Illustrated Guide''.
