Spanish speaking casinos are abundant. Spain relaxed gambling legislation in the 1970s, and the country has always been rather partial to gambling-related activity. The industry was regulated in 2012, with the exception of slots which were covered in legislation passed in 2014. Over the years, there has been an increasing move towards liberalizing online casinos, although some restrictions remain.

There are dozens of casinos in Spain, and now slots games are also a big hit. Spanish is spoken by an estimated 437 million people globally. It ranks highly in terms of number of native speakers. Spanish is spoken in Argentina, Chile, Colombia, Ecuador, Venezuela, the United States, Spain, the Canary Islands, and many other countries. As such, Spanish speaking casinos have a broad-base to cover, and legislation will vary from one country to the next.
