Silver Ball Gardens was an amusement arcade in Berkeley, California. It was founded by Byron Won in 1973 and located in a second-story loft at 2518-A Durant Avenue. Silver Ball Gardens was decorated with interior murals by Berkeley artist Eugene Legend, and a large exterior mural by Berkeley artist Bobby Vitaliano.
In the late 1970s, Silver Ball Gardens was purchased by Masayoshi Son and Hong Lu, two entrepreneurs running an arcade-game importing business in Berkeley. Son would go on to found SoftBank Group in 1981, and Lu to found UTStarcom in 1995.
