Casino, as locals in Cuba call the dance – "Salsa" primarily exists as something to eat or as "el baile de las hoteles" for tourists – gradually evolved as a couples dance from the mid-1950s onwards out of the Rueda de Casino, which had originally emerged from Cuban Son. (The various Salsa styles, also Salsa Cubana, on the other hand, only developed in the 1970s in the United States as a combination of ballroom and Latin (especially Puerto Rican) influences and was then exported to the rest of the world from there.
Particularly characteristic of Casino are the circular basic step (guapea) as well as the dancers both dancing around the partner, with the main accent of the steps directed forward (in walking direction). With this, Casino provides a clear contrast to the linear step patterns of the Salsa styles developed outside Cuba from the 1970s.
In recent years – especially with timba music – also longer open sequences (without hand contact) have appeared in Casino, usually using Reggaeton, Rumba or Afro styling fitting to the music.
