A Game of Concentration (also known as Concentration and Hunt & Score) is a video game developed by Atari, Inc.
Released in 1978 for the Atari VCS (later renamed to the Atari 2600). It was programmed by Jim Huether, and is a version of the classic memory game. It was one of a handful of games that used Atari's keypad controllers.
The game was released by Sears for the "Sears Video Arcade" under the name Memory Match.
The game is played using a matrix of numbered panels, either 4 x 4 (for 16 panels) or 5 x 6 (for 30 panels). Using the keypad, players enter the number of the panels they wish to reveal. If the images behind the two panels match, the panels are removed and the player scores 1 or 2 points, depending on what difficulty the switch is set to, along with an extra turn.
