Rueda de Casino (Rueda) is a particular type of Salsa round dance, born from Casino. People incorrectly call it "Casino Rueda" or "Cuban Salsa." The origins of the name Casino are the casinos deportivos, the dance halls where a lot of social dancing was done among the affluent, white Cubans during the mid-20th century and onward. Casino danced with multiple partners in a circular fashion emerged in 1956 under the name "Rueda del Casino," and has become a popular dance throughout the world.
Pairs of dancers form a circle, with dance moves called out by one person, a caller (or "líder" or "cantante" in Spanish). Many moves have hand signs to complement the calls; these are useful in noisy venues, where spoken calls might not be easily heard. Most moves involve the swapping of partners, where the partners move around the circle to the next partner. The combination of elaborate dance combinations and constant movement of partners create a visually spectacular effect.
The names of the moves are mostly in Spanish, some in English (or Spanglish; e.g., "un fly"). Some names are known in slightly different versions, easily recognizable by Spanish-speaking dancers, but may be confusing to the rest. Although the names of most calls are presently the same across the board, the different towns in Cuba use their own calls. This is because the pioneers of Rueda de Casino wanted to keep others from participating in their Rueda. Many local variations of the calls can now be found. They can change from town-to-town or even from teacher-to-teacher. There are many different variations of moves in Rueda de Casino.
