Robbing the Kong (搶槓)

What is Robbing the Kong?

Robbing the Kong (搶槓), pronounced cheung gong, is a 1-faan bonus in Hong Kong Mahjong awarded when a player declares a winning hand using a tile that another player has just added to an existing exposed pung to upgrade it into a kong. It is one of the most distinctive win-action patterns in HK Mahjong because it interrupts another player’s mid-turn action.

How Robbing the Kong works

A player who already has an exposed pung of a tile (claimed earlier from a discard) and later draws or holds the fourth identical tile may declare an “Added Kong” (加槓) — the act of converting their pung into a kong by laying down the fourth tile. Normally this is a routine operation that triggers a replacement draw.

However, if the tile being added to the kong is the exact tile another player needs to complete their winning hand, that player may interrupt the kong declaration and claim the tile as their winning tile instead. The kong is canceled, the would-be konging player loses the action, and the winning player scores Robbing the Kong as a 1-faan bonus.

Example hand

Restrictions

Robbing the Kong has specific rules that distinguish it from a standard discard win:

• It applies only to Added Kongs (加槓), not to Concealed Kongs (暗槓 — four self-drawn identical tiles declared at once) or Exposed Kongs (明槓 — claimed from a discard).
• The winning tile is the one being added to the existing pung, not any tile in the player’s hand.
• Some house rules treat the would-be konger as the discarder for payment purposes, applying the discarder-pays-double rule.

Faan value: 1

Robbing the Kong is worth 1 additive faan, stacking with the hand’s structural pattern. It is rare in actual play — depending on hand exposure and timing — but always pays 1 faan when it occurs.

Common combinations

Robbing the Kong stacks with most patterns:

• Robbing the Kong + All Triplets (對對胡) — 1 + 3 = 4 faan.
• Robbing the Kong + Mixed Flush (混一色) — 1 + 3 = 4 faan.
• Robbing the Kong + Concealed Hand (門前清) — 1 + 1 = 2 faan, often combined since the winning hand doesn’t include the robbed tile as a meld.

Robbing the Kong is mutually exclusive with Self-Pick (自摸), since the win comes from another player’s action, not the wall.

Strategic note

Robbing the Kong creates a defensive consideration for any player about to declare an Added Kong: if an opponent’s hand is one tile from winning and that tile is the one being added to the kong, the kong declaration hands them the win. Cautious players inspect the table for exposure patterns suggesting a near-complete hand before declaring an Added Kong on a contentious tile.
