Tomorrow is a big event at my university. I’d like to make a fun thing where the people of the Board Game society I am in can try to find me for a riddle, kind of a Where is Waldo in a place where there is a crap tone of people to find the NPC that’ll give them a Riddle (Maybe something to win? No idea how I could do that detail)
You answer is right. I heard the solution as follows: Would the other guard say that you are guarding the right door? And then you revert it. Yours solution is better. The XKCD and the video made me laugh, thanks.
