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.)
Riddle:
My little circle of friends here, getting bumped off one-by-one, reminds me of Agatha Christie's famous murder mystery "Ten Little Indians", where a small group of people are knocked off, one at a time, until only the killer and one person is left. The main difference is that in Christie's novel, the last survivor was to die by hanging, but in my situation, the sole survivor will be given "The Chair"! Should this person call the police? Is there a life-and-death scenario going on here, or is everyone's safety assured? What exactly is happening?
Answer: The person, along with a small group of their friends, is engaged in a game of Musical Chairs. "The Chair" is always reserved for the last person left.

Riddle:
Shirley grew up in a family that loved desserts ------ especially one dessert! Many arguments occurred during dessert time in Shirley's family, and on a few occasions, these disputes nearly led to blows. The person serving the dessert was usually the one accused of creating the contentious atmosphere. The accusations usually centered around the color distribution allotted to each family member. People were always o.k. with the amount of orange, white, light green, and yellow they received, but the distribution of the red was always a major point of contention. God help anyone who dared to pass out more of the red part of the dessert to any one person sitting at the table, for if they did, all hell would break loose! It's amazing to think a simple canned desert could cause such an uproar, but it did, and in certain families, still does today. What is this common dessert which caused such a commotion in Shirley's family?
Answer: Fruit cocktail. If the red cherry pieces are not evenly distributed, people sometimes get upset. The Del Monte company actually had to add a separate can to their lineup of fruit cocktails to appease their customers due to this problem. They call it Very Cherry, and it contains more cherries than their original can.
Riddle:
In the home where Mabel resides, she has a reputation for walking very slowly, even though she is only 40 years old. Her slowness doesn't appear to be related to arthritis or to other medical ailments, but is more likely due to heredity, as her parents both had the same condition. Mabel does not use a walker or a cane to move about, and a wheelchair would be out of the question. Mabel is an extreme introvert who basically stays in her home 24 hours a day, 7 days a week. Although it sounds a bit strange, you could say, even when Mabel leaves her home --- she stays at home. Although she frequently leaves the front door to her home open, she is easily frightened, causing her to immediately shut that front door when she feels threatened in any way. Mabel's caretakers frequently laugh at her and sometimes point their fingers at her as she struggles to move along. The caretakers allow Mabel only small rations of food and water each day, and they never give her a shower. Where are the abuse investigators? Where is the justice? Or are things not as bad as they appear to be for Mabel?
Answer: Mabel is a Box Turtle who is the house pet of a family with several children. She is well cared for, but instinctively closes the front door of her shell and pulls her legs in if she senses danger, which includes inquisitive children.
