1. Executive Summary GameHouse Mahjong Medley is a casual puzzle video game developed and published by GameHouse , a studio known for its extensive library of time-management, hidden object, and card/board games. Released primarily for Microsoft Windows in the early 2000s (circa 2003–2005), the game is a digital adaptation of the classic solitaire mahjong tile-matching game (often called Shanghai, Mahjong Solitaire, or Taipei). Unlike the traditional four-player mahjong game, Mahjong Medley focuses on clearing a layout of 144 tiles by matching open pairs.
