Logic puzzle:
Three doors. One puppy. The math is sneakier than your gut.
Behind one door is a puppy. Behind the others, broccoli. You pick a door. Then a friend who knows what's behind each door opens one of the OTHER doors โ and shows you broccoli. Now they ask: do you want to switch your pick to the last unopened door, or stay? Almost everyone says it's 50/50. It isn't.

OK fine, what's the answer? โ
Switch! Your friend's clue secretly told you a lot โ they were never going to open the puppy door. So they basically pointed at the prize. Switching wins 2 out of 3 times.
