In an August 3, 1973, memo to the Atari engineering department, co-founder Nolan Bushnell laid out plans for the company to create a prototype 20-player version of "Gotcha" in time for a trade show later that year, though no such game was ever made. Instead, released at the same time as "Gotcha" and showcased at the early November 1973 Music Operators of America (MOA) Music & Amusement Machines Exposition were two additional versions of "Gotcha": one with a tinted color overlay, and a true multi-color version of "Gotcha" with red, blue, and green colors. The color version of "Gotcha" was not widely produced, with between 20 and 100 machines released, but is believed to be the first color arcade game ever made, released over a month before "Wimbledon", a color "Pong" clone.
