Naki

Naki

Naki (鳴き) is a call or claim used in mahjong to complete a meld using another player’s discard. When you declare naki, you take that discarded tile to form a chi (sequence), pon (triplet), or kan (quad), immediately exposing your meld on the table. This action opens your hand and makes it visible to all players, which affects your eligibility for certain scoring patterns (yaku).

How Naki plays out at the table

The term “naki” comes from the Japanese verb “naku” (鳴く), literally meaning “to cry out” or “to call.” In mahjong, it represents the vocal and physical action of claiming a discard before it enters the discard pile permanently.

How Naki Works

When a player discards a tile, other players have a brief opportunity to claim it. If you can use that tile to complete a meld, you may declare naki by calling out the appropriate action:

• Chi (chow): Claiming a discard to form a sequence of three consecutive tiles of the same suit
• Pon (pung): Claiming a discard to form a triplet of three identical tiles
• Kan (kong): Claiming a discard to form a quad of four identical tiles (also called minkan when using a discard)

The claiming priority follows a hierarchy: kan claims take precedence over pon claims, which take precedence over chi claims. If multiple players want the same discard, call type decides: ron beats pon and kan, which beat chi. Note that chi may only be called on a discard from the player to your left.

Opening Your Hand

Once you declare naki, your hand becomes open (exposed). You must place the completed meld face-up on the table in front of you, allowing all players to see your tiles and progress toward completion. An open hand provides strategic information to opponents and limits your options for certain high-scoring yaku.

Restrictions on Yaku

Using naki to form melds restricts your eligibility for several yaku patterns, particularly those requiring a closed hand (concealed hand). For example:

• Menzen Tsumo (concealed hand self-draw) requires your entire hand to remain closed
• Honitsu and Chinitsu (half flush and full flush, one-suit hands) may have reduced point values when your hand is open
• Pinfu (all sequences with a valueless pair) and other closed-only patterns become unavailable

However, some yaku work perfectly well with open melds, such as Toitoi (all triplets), Yakuhai (value triplets), and Tanyao (all simples, under kuitan rules).

Strategic Considerations

Declaring naki involves strategic trade-offs. While it accelerates your progress toward a winning hand by completing melds quickly, it sacrifices the higher point values associated with closed hands and restricts your yaku options. Experienced players carefully evaluate whether claiming a discard is worth these restrictions.

Seeing Naki in play

During a hand, the discarder plays a 5-bamboo tile. You have 3-bamboo and 4-bamboo in your hand, allowing you to form a chi (sequence). You declare “chi!” and claim the discard, placing the three tiles face-up on the table. Your hand is now open, and you continue playing toward your winning hand, though you’ve restricted yourself from scoring certain yaku that require a closed hand.
