Hacky Holidays (Unlock the City edition) is a jeopardy CTF hosted on the Deloitte Hackazon platform, where you can test and improve your skills with all sorts of challenges (technical puzzles) related to cyber security and emerging technologies.

=====
You’ve been officially chosen to compete in UNLOCK THE CITY from July 8. till July 26.

Help! The smart city is in trouble. An A.I. algorithm went rogue in the once so peaceful, intelligent city. It's chaos out there.

To regain control and restore peace, we need a group of talented hackers. Each hacker or hacking team will unlock the city in phases by solving a set of challenges in four city districts. The city council has announced that the event's winner will be appointed "Mayor" of the City to sweeten the deal. Additionally, the best hacker in a particular district will become the "Sheriff" for that district.

Can we count on you to unlock the city?
