The answer to this question is difficult to determine as there is no specific law that governs bingo in Spain. However, there may be some legal issues that could arise if bingo were to be conducted in a way that violated Spanish civil or criminal law. Additionally, there may be social implications to conducting bingo in Spain given the country’s longstanding Catholic heritage. As such, it is difficult to say definitively whether or not bingo is illegal in Spain.
However, it would likely be considered an illicit activity, and participants could face sanctions from the government. In short, it is unclear whether or not Bingo is technically illegal in Spain, but it would likely be considered an illicit activity that would be subject to government regulation or sanction.
