What you will be doing
Each challenge hands you a file, a page or a hint. Somewhere in it is a flag
that looks like TBZ{something_like_this}.
Paste it into the box under that challenge. Right answer, you get the points.
Points decay: the first person to solve a challenge earns the full value, and it drops as more people solve it. Whatever you earn is locked in at that moment — your score can never go down later. That is what separates the top three from everyone who merely finished.
Bring a laptop, a browser, and whichever tools you like. No paid accounts are needed for anything in this event.
Before you start
- Register with a working email. Prizes and certificates go to the name on your registration, so use your real one.
- Pick a handle you are happy to be seen with. The scoreboard shows only your handle — never your name, email or phone.
- Read the rules. They are short, and one of them is the difference between winning and being disqualified. Rules →
Registration takes under a minute. Entry is Rs 100 (US$1 from outside Pakistan).
