The increased use of digital devices and applications has led to a rise in phishing attacks. We develop a serious game to raise awareness about phishing attacks and help people avoid these threats in a risk-free learning environment. This game targets three types of phishing—clone phishing, SMS phishing, and spear phishing—and uses a Large Language Model to dynamically generate dialogues and questions. It also incorporates state randomization and time-limited challenges to enhance the gameplay. We evaluated two groups of participants and found that those who played the game showed, on average, a 24% increase in awareness and a 30% boost in confidence.
