All Fours, also known as
High-Low-Jack or
Seven Up, is an English tavern
trick-taking card game that was popular as a gambling game until the end of the 19th century. It is the eponymous and earliest recorded game in a family that flourished most in 19th century North America, notable other members being
Auction Pitch,
Pedro and
Cinch, which competed against
Poker and
Euchre. Nowadays the original game is especially popular in
Trinidad and Tobago, but a simpler variant has also survived in parts of England.
