Slots became popular in the 1920s and were most popular in resort areas. They remained popular throughout the Great Depression. However, some cities were not comfortable with these games and banned them. Despite these laws, many people still favored them. Then, in the 1980s, slot manufacturers began incorporating electronics into their machines, which allowed them to weigh the symbols.
