    • Power cut Riddle

      Sonia is going on an extended trip for three weeks. She lives in a remote area where there are frequent electrical power outages which can last up to three or four days. Sonia has quite a bit of food in her freezer which would go bad if it thawed and then re-froze. She does have digital clock and a VCR which would flash 12:00 if the power went out.

      Unfortunately the clock and VCR flash even if the power only goes out for a few seconds.

      What can Sonia do so that when she returns home she will be able to determine whether the power was out long enough to thaw her food?

      Asking a neighbour whether the power was out, isn’t a reliable option because the nearest house is half a mile away, and one house may have power, while another house may have no power. She won’t be able to have a neighbour check on her house every day, and has no one to house sit.

    • Son Kidnapping Puzzle

      The Queen lives in a beautiful castle with her only son and a sheep-dog named Sir Foo Foo. One day the Queen decides to go out for a spot of tea with some friends. She leaves her eight-year-old son in the care of her trusted servants. The 18 servants are: Harold the health instructor, Griffith the gardener, Tiffany the private tutor, Philip the photographer, Magdalina the maid, Boris the Butler, Geraldo the groundskeeper, Bernadette the barber, Sandy the sweeper, Anastasia the accountant, Constantine the carpenter, Joel the jester, Lucy the launderer, Sadie the seamstress, McKenzie the musical instructor, Lawrence the lawyer, Dorothy the dentist, Devon the doctor, and Surlamina the Secretary of State. When the Queen came home she discovered her son was missing and that he was kidnapped. The Queen came to a conclusion that it must’ve been one of her servants who kidnapped her son because he was too young to leave on his own and Sir Foo Foo was harmless.

The alibis are as follows: Harold was lifting weights, Griffith was planting roses, Tiffany was checking homework, Philip was taking pictures of the botanical garden, Magdalina was making the beds, Boris was cleaning the banisters, Geraldo was supervising Griffith , Bernadette was trimming Sir FooFoo’s hair, Sandy was sweeping in the corners, Anastasia was managing the Queen’s affairs, Constantine was building a birdhouse, Joel was coming up with the jokes, Lucy was doing the laundry, Sadie was designing a dress for the Queen, McKenzie was playing the flute, Lawrence was suing the bank, Dorothy was preparing to extract the Queen’s tooth when the Queen came home, Devon was examining an x-ray of the Queen’s arm, and Surlamina was being a Secretary of State.

    • Dice Puzzle

      The name of the game is Petals Around the Rose, and that name is significant. Newcomers to the game can be told that much. They can also be told that every answer is zero or an even number. They can also be told the answer for every throw of the dice that are used in the game. And that’s all the information they get.

      The person who has the dice and knows the game, rolls five dice and remarks almost instantly on the answer. For example: in Roll #1 the answer is two.

      Roll #1. 4 1 6 3 6

      “The answer is what?” says the new player.

      “Two.”

      “On that roll?”

      “Yes.”

      “Would it still be two if I moved the dice without turning any of them over, just rearranging the pattern?”

      “I can tell you only three things: the name of the game, the fact that the answer is always even, and the answer for any particular throw. In this case the answer is two.”

      “So that’s how it is. What am I supposed to do?”

      “You’re supposed to tell me the answer before I tell you. I’ll give you all the time you want, but don’t tell me your theory, just the answer. If you figure it out, you don’t want to give the idea away to these other jokers around you. Make them work for the answers, too. If you get the answer right on six successive rolls, I’ll take that as prima facie evidence that you understand the game.”

      “OK, roll again.”

      Roll #2. 5 6 5 4 4

      “I give up. What’s the answer?”

      “The answer is eight.”

      “Roll again.”

      Roll #3. 3 5 5 5 6
      The answer is fourteen.

      Roll #4. 2 6 2 1 4
      The answer is zero.

      Roll #5. 4 3 2 1 3
      The answer is four.

      Roll #6. 6 5 6 2 2
      The Answer is ……?

    • Camel travel riddle

      Six Tasmanian camels traveling on a very narrow ledge, encounter six Tasmanian camels coming the other way.

      As everyone knows, Tasmanian camels never go backwards, especially when on a precarious ledge. The camels will climb over each other, but only if there is a camel sized space on the other side.

      The camels did not see each other until there was only exactly one camel’s width between the two groups.

      How can all camels pass, allowing both groups to go on their way, without any camel reversing?

      Hint: to help visualize, use paper clips or coins.
