Even those of us who have tin ears can make music with Latin America's musical rattle, the maraca. The idea in Samba de Amigo is to use visual cues to shake your maracas in time with the music's rhythm. Although that might sound easy, it's not. The visual cues prompt you more than just to shake them, but where to shake them, and in three levels between your head and your knees. In other words, think of Samba de Amigo as a cross between Dance Dance Revolution and semaphore. The game requires quick reflexes, great timing, and powerful concentration.
