meld

A meld is a valid combination of cards grouped and revealed as a scoring or action unit in a card game. The two most common meld types are sets (three or more cards of the same rank — three kings, four sevens) and runs (three or more cards of the same suit in consecutive rank order — 5-6-7 of hearts). Rummy-family games are built around melding: the goal is to arrange your hand into valid melds and declare them.

Meld rules define what combinations count, when they may be declared, and how they interact with the rest of play. Some games require a minimum size or value to meld first (an opening meld threshold). Some allow players to extend existing melds on the table — adding a fourth king to a three-king set, or extending a run with adjacent cards. Some lock melded cards permanently, while others allow them to be rearranged. These variations produce very different strategic textures: games with meld extension encourage building on what others have played, while games with locked melds make the first declaration a commitment.

The strategic tension in melding games is between completing melds and managing risk. Holding cards to complete a meld means keeping them in your hand, where they count against you if an opponent declares first. Declaring melds early reveals information to opponents — they can see what you are collecting and adjust their strategy. This tradeoff between hidden potential and public commitment is the central decision in most melding games, and it parallels the broader card-game theme of managing the tension between private information and public action.
