Is Sudoku Addictive?
People have jokingly called themselves "Sudoku addicts" since the original worldwide craze of 2005. Sudoku can be highly engaging because every completed row, discovered number, and solved puzzle provides a sense of accomplishment. However, enjoying Sudoku frequently isn't the same as having an addiction. It becomes a concern when playing feels uncontrollable or regularly interferes with sleep, relationships, or everyday responsibilities.
