four
Four is correct, Anant.
You place three coins together in a triangle, and the fourth goes on top.
Great job. You are today’s winner.
Oh man Anant, I guessed 3 and then saw your answer and knew I should have changed it to 4. That was my original answer. Who wants to answer a coin riddle I found? I can leave it here: Toss A Coin
