(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

uninspired challenge writing the day before the CTF
"can i DM you about [challenge]?" - DMs
challs too easy
people asking questions that can be solved with 30 seconds of research
challs too hard
that one really nice dude asking for hints
massive amounts of unnecessary pings
so many PMs overnight
:star: perfect infrastructure
"your challenge is broken, i can't solve it"
people expecting you to check their code
@organizer
accidentally releasing a chall with a :cheese: solution
