Riverboat Gambler is a gambling themed pinball machine produced by Williams. Pinball machine designer Mark Ritchie reportedly sings the song that plays during the game, whose gravel-voiced, New Orleans-style male voice sounds similar to Louis Armstrong.
In the center of the head of the machine, a vertical roulette wheel operates more like the Wheel of Fortune than an actual roulette wheel and does not have a ball. 7 of 16 sections are black, 7 are red, which alternate, with two green spaces that have stars on opposite sides. Located directly above the roulette wheel, a four digit display keeps track of virtual chips. The player uses chips earned on the playfield to bet on the roulette wheel.
