On this page there's lots to do
finish a thing and find a clue

But beware when you play
For Sunday is the hardest day

Friday and Saturday are not easy either
do it Monday or Tuesday for a breather

Wednesday and Thursday are probably all right
you will only have a little fight

When you finish, the flag will appear
You can stay on this page, it is here.

And when you've reached this state of bliss
You'll know because it looks like this:

flag{the_secret_you_are_looking_for}

The one in the meta tags don't count,
That is old and already been found


The answers will be revealed on 4/24/26 during our LIVE weekly PODCAST 3pm ET!
