Color TV-Game 15 is the sequel to Color TV-Game 6. This game features fifteen different variations of Light Tennis, whereas the original only has six. Like Color TV-Game 6, Color TV-Game 15 was very successful, selling over a million copies in Japan. The controllers were now separate from the console, while in the original the players were required to turn the knobs on the actual console.

It appears in Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros. Ultimate as an Assist Trophy where it plays a game of Light Tennis on the stage. The score appears in the top corners of the screen and increases when the ball goes off-screen. The ball bounces off the platforms in the stage and opponents hitting into either paddle or the ball get hit with huge knock-back, possibly killing them at low percentages.
Color TV-Game 15 is the only Assist Trophy in Super Smash Bros. Ultimate that doesn't have a Spirit.
