Crosswords in the 1920s, such as RAGE (4 letters) and MANIA (5 letters), were popular puzzles that were first published in the New York World newspaper in 1913. They quickly gained popularity and became a staple of newspapers across the United States. The puzzles were often used to test the knowledge of readers on topics such as literature, history, and current events. The puzzles also provided an entertaining way for people to pass the time during the Roaring Twenties.
