The original “Simon”, popularized in the late 1970s, was a lightweight plastic toy with 4 colored buttons, red, green, yellow, and blue, that played tones using the microchip-generated sounds of the era. Players were required to correctly repeat a random and increasing number of tones from the following set of just 4 pitches: E, A, C#, E (octave), representing a single A major triad.
The Guinness world record for the most sequences completed in a game of "Simon Says" is 84. This record was achieved on November 28, 2020, in Caesarea, Canada.
