Cryptex is one of India's largest Online Treasure Hunts (OTH), conducted annually by the students of IIT-Hyderabad.

The participants go through gruelling puzzles designed to test their deduction skills and intuition over a period of 54 hours. The questions are a series of cryptic images/videos/audio clips (any file, really). Head on over to our Instagram page for some example questions.

The first three players to beat all the levels are announced as the winners of the event. Clear your calendars and put your thinking caps on for this intense but fun weekend! You can pre-register for the event at:
