  • Dude

    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
