Answer: The three words are BACON, CUPCAKE, and LOVE. This riddle is open to many interpretations, so there are multiple answers. For example, BACON doesn't end with an E (unlike CUPCAKE and LOVE). However, CUPCAKE has three vowels (while BACON and LOVE have two each). On the other hand, LOVE is an emotion (while BACON and CUPCAKE are foods). No matter which word you pick, there is at least one reason for it being correct.

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: Irene and her friend Mark were walking down the street when they saw two houses. Mark wanted to play a game with Irene. He said, "One family lives in each house. And each family has two pets: either dogs or cats. The first family has a dog who likes dry food, while the other pet likes canned food. The second family has a 6-year-old dog and a newborn pet. If you can guess which family has a cat, I'll take you out for lunch." Irene manages to get the riddle right, and the two of them go out for lunch. Which family did she choose?
Answer: Irene chose the first family. There are three different possibilities for the pets that the first family has: 1) an older dog and a younger cat; 2) a younger dog, and an older cat, and; 3) two dogs. Two of these options involve a cat, and all of them are equally possible, so the chance of the first family having a cat is 2/3. There are two different possibilities for the pets that the second family has: 1) a 6-year-old dog and a newborn dog, and; 2) a 6-year-old dog and a newborn cat. One of these options involves a cat, and both of them are equally possible, so the chance of the second family having a cat is 1/2. Irene's odds of winning will be higher if she chooses the first family.
