Riddle: A man rode his horse to the top of a high hill. He tied his horse to a large birch tree, and removed a blanket, a flint and steel for making fire, and a small hatchet to cut down a bunch of green saplings. He then gathered a bunch of dried leaves and took them, along with the green saplings, to an open area near some smaller rocks. Using the flint and steel, he tried to start a fire with the leaves and green wood. As the fire struggled to burn, the man did something remarkable. He suddenly took his blanket and covered the fire with it. Apparently, regretting his actions, he removed the blanket from the smoldering fire; but then, a few seconds later, he placed the blanket back over the fire. Again and again he repeated his actions of throwing the blanket on and off the fire. Was this man an obsessive-compulsive pyromaniac, or was there some kind of method to his madness?
Answer: The man was a Native American Indian in the old West who was sending smoke signals to his tribe.
Riddle: You have 52 playing cards, 26 red, and 26 black. You draw cards one by one. A red card pays you a dollar. A black one fines you a dollar. You can stop any time you want. Cards are not returned to the deck after being drawn. What is the optimal stopping rule in terms of maximizing your expected payoff? Also, what is the expected payoff following this optimal rule?
Answer: The solution to this problem is, in my opinion the most difficult to understand of all the puzzles. Indeed I was unable to solve it and didn't receive a complete solution until two years after originally posting it. The final solution, in the form of the spreadsheet was sent to me by Han Zheng. For this reason I have left on the page the thoughts i had before I had the final solution as they represent an easier to understand and more simplistic approach. Also the reasoning may help you arrive at the final solution by yourself or help you understand it. I would recommend reading that answer before you dive into the full answer. But an important thing to note are that as the player we can't lose this game as we can gamble till all the cards are drawn and our net position is zero. From our earlier analysis it is clear we need a dynamic quit rule. A singal value is not sufficent. We must, at each stage consider what cards are remaining, and therefor the probability of a positive or negative outcome from drawing again. For the explanation i will ask you first to consider a deck containing only 6 cards, 3 +ve & 3 -ve (note i'm no longer calling the cards black and red, it confuses me.)
