MCP #105 Simon Traditional Cache

Simon is an electronic game of memory skill invented by Ralph H. Baer and Howard J. Morrison,[1] with the software programming being done by Lenny Cope and manufactured and distributed by Milton Bradley. Simon was launched in 1978 at Studio 54 in New York City and became an immediate success. It became a pop culture symbol of the 1980s.

The game unit has four large buttons, one each of the colors red, blue, green, and yellow. The unit lights these buttons in a sequence, playing a tone for each button; the player must press the buttons in the same sequence. The sequence begins with a single button chosen randomly, and adds another randomly-chosen button to the end of the sequence each time the player follows it successfully. Gameplay ends when the player makes a mistake or when the player wins (by matching the pattern for a predetermined number of tones).
