About Google CTF
The main event is aimed at experienced CTF teams and is one of the harder fixtures on the circuit. In several past years Google also ran a separate Beginner's Quest later in the summer for people new to CTFs.
It is free to enter, played online in teams, and you need an account to register and submit flags. The event usually runs for 48 hours in late June, starting and ending at 18:00 UTC.
