Karaoke Revolution allows PlayStation 2 gamers to show off their singing skills and get real-time feedback on their performances. It's similar to Dance Dance Revolution, but with singing instead of dancing. Players sing using the Logitech PS2 Headset (or other approved PlayStation 2 USB microphone devices). The game rates the player's performance based on their vocal pitch and timing. A visual indicator shows the player's current pitch in real time and also the pitch of vocals of the original song. If the original notes of the song are too high for the player's vocal range, the game allows the player to sing at higher or lower octaves to hit the correct notes. If the player sings well, the crowd gets into the performance by clapping, cheering and dancing. If the performance is bad, the audience becomes bored and the user can get booed off the stage. Single Player Game Modes include:

• Arcade Mode: where users sing 3–5 songs and try to score big points
• Showtime Mode: Players start at a living room party and work to a huge concert at the Enormobowl. Additional venues include: a subway station, The Pit Stop, a county fair, the Superstar TV show, Club Avalanche, and a royal hall.
• Karaoke Mode: Players can enjoy singing the song without having to worry about bring rated or scored.

Multi-player Game Mode include:

• Arcade Mode: 2–8 players perform songs and try to be the player with the highest score at the end of each round. The player who wins the most rounds is the winner.
• Karaoke Competition: 3–8 players compete against each other. The main twist of this mode is that each player rates the performance of the other players to determine the winner of the Karaoke competition.
