Merlin (sometimes known as Merlin, the Electronic Wizard) was a handheld electronic game first made by Parker Brothers in 1978. Merlin is notable as one of the earliest and most popular handheld games, selling over 5 million units during its initial run, as well as one of the most long-lived, remaining popular throughout the 1980s. A version of the game has been recently re-released by the Milton Bradley Company.
Merlin was created by Bob Doyle, a Harvard PhD. and inventor who had previously worked with NASA. Merlin took the form of a rectangular device about eight inches long and three inches wide. The play area of the game consisted of a matrix of eleven buttons; each button contained a red LED. The array was encased in a red plastic housing, bearing a slight resemblance to an overgrown touch-tone telephone. Four game-selection and control buttons were also placed at the bottom of the unit; a speaker took up the top section. Supporting electronics (including a simple microprocessor) were contained within the shell of the game.
Parker Brothers later released Master Merlin with more games, and the rarer Split Second, where all games involve time with a more advanced display, sporting line segments around the dots. Both of these share the same general case shape, and came out a few years after Merlin.
Merlin's simple array of buttons and lights supported play of six different games, some of which could be played against the computer or against another person.
