What is this

Real-world puzzles. First solver takes the prize.

Cipher Signal Labs runs themed competitive puzzle events that are made to be discovered out in the real world. Each event unfolds in phases, and every phase asks for the specific skill that puzzle calls for. Anyone can play for free. The sponsor names the prize up front, and it goes to whoever cracks the code first.
