Gee Bee by Tōru Iwatani, was game manufacturer Namco's first internally developed digital game. It combined the brick-breaking gameplay of Breakoutwith a pinball playfield as players used a double-decker set of paddles to accumulate points and bonuses earned by hitting various targets represented in full color graphics."
