Party games are games that are played as a part of a party, to facilitate interaction and provide entertainment and recreation at social gatherings. Categories include icebreakers, parlour , picnic , and large group games. Other types include pairing off games, and parlour races. Different games will generate different atmospheres so the party game may merely be intended as an icebreaker, or the sole purpose for or structure of the party. As such, party games aim to include players of various skill levels and player-elimination is rare. Party games are intended to be played socially, and are designed to be easy for new players to learn.
A game can support a relatively large or undefined number of players, compared to more traditional board games or card games that require a small, set number of players. Some games, especially commercial games, have a set limit based on available equipment; others are limited by other mechanics of the game like time for each turn, while still others have no practical limit.
