Sorry everyone, this event is supposed to start at 22:00 UTC, not 17:00 UTC :(


PharisaeusNov. 14, 2020, 5:39 p.m.

If you're a traveller from the future, wondering if you should play another SquareCTF, the answer is: no. It's trash-tier, guessy shit. Arguably the worst CTF I've seen so far this year. If you value your sanity, be somewhere else.
A word of advice to organizers: Don't. Really, just don't.


sarastroNov. 15, 2020, 8:13 p.m.

The CTF has a unique site, really nice moderations, and good communication. They love criticism and advice which makes them good. The challenges were a bit on and off and it was mostly dominated by RE. Good challenges overall and is not bad at all.
