Here is what you need to do:
-
Register your team.
This only needs to happen once per team,
so if somebody else on your team has already done it,
you don't need to.
-
Get an overview of puzzles,
and start working on something.
The list of open puzzles changes over time,
you need to reload the page to get the current version!
-
Check the scoreboard
in another tab,
to see how your team is doing.
