Rhythm game or rhythm action is a genre of music-themed action video game that challenges a player's sense of rhythm. Games in the genre typically focus on dance or the simulated performance of musical instruments, and require players to press buttons in a sequence dictated on the screen. Many rhythm games include multiplayer modes in which players compete for the highest score or cooperate as a simulated musical ensemble. Rhythm games often feature novel game controllers shaped like musical instruments such as guitars and drums to match notes while playing songs. Certain dance-based games require the player to physically dance on a mat, with pressure-sensitive pads acting as the input device.
