IEEE Puzzlers is an online community within IEEE that offers challenging mathematical brainteasers to engage and inspire researchers, engineers, and other professionals. The community aims to develop critical thinking, foster creativity, and strengthen the sense of community among IEEE members. Activities include puzzle creation, solving events, and competitions, with badges and recognition for participants. The initiative, launched in April 2021, relies on volunteers and utilizes IEEE Collabratec for community-building and networking. The community has grown to over 7,000 participants and has received awards for its engagement and impact.
