Seven Up

Seven Up, also known as All Fours or High-Low-Jack, is an English trick-taking card game where players score points in four categories: High (highest trump in play), Low (lowest trump), Jack (jack of trumps), and Game (game points from cards won). Players follow suit and trump cards beat other suits. The game has been documented since the 17th century and was widely played in Britain and early America.

Seven Up and All Fours are essentially the same game, with Seven Up being a common American name for the traditional English card game. The game is also called High-Low-Jack in some regions. All these names refer to the trick-taking game documented since the 17th century with scoring based on High, Low, Jack, and Game points.

Seven Up is typically played by 2 to 4 players using a standard deck, with partnerships common in 4-player games. The trick-taking mechanics work well for various group sizes, though the dynamics change significantly between 2-player and 4-player formats. Traditionally, it was a popular tavern and home game in Britain and America.

Seven Up and its variants continue to be played, though less commonly than during their peak popularity in 18th and 19th century Britain and America. The game survives in some card-playing communities and has influenced the design of later trick-taking games. Historical card game enthusiasts and traditional game preservation groups maintain interest in these classic games.
