George K. Kostakis

Hi! I’m George Kostakis — puzzle designer, escape room creator, and author.

For over a decade, I’ve been designing immersive escape rooms, team-building experiences, and mind-bending puzzles that challenge players to think in unconventional ways. My work blends storytelling, logic, and interactivity — whether it's in physical spaces or on the pages of a book.
