Many people associate the words freaks and weirdos with carnival jobs... and The Riddler hasnt done much to help this stereotype. After leaving education to focus on his newfound obsession with puzzles Edward Nigma established a crooked puzzle booth at a carnival. He had devised an unbeatable puzzle which competitors could pay a small fee to try to win. As the customers would inevitably fail he never had to pay out any prize money this sounds like an okay income, but it didnt satisfy the up-and-coming villain. Growing frustrated with using his intellect for trivial purposes, The Riddler closed his cryptic carnival attraction and turned to a life of crime in order to make his money. Obviously the carnival was a waste of his precious talents, as he went from making menial money to stealing masterminding massive heists extremely quickly.
