  • prisionor-warden-puzzle

    23 selected prisoners are summoned by the warden. He gives them a choice of playing a game with him that might ensure their escape from the prison or might as well lead them towards painful death. The prisoners think that this is the only chance for them to be free again and agrees to him.

    The warden tell them that there is a room which has just two switches which are labelled 1 or 2. The switches may be up or down and the condition is not known at present. They are not connected to anything. The warden may select any prisoner on any day and send him to the switch room. The prisoner will have to select any one switch and reverse its position i.e. if it is up, he will turn it down and if it is down, he will turn it up. He can and must only flip one switch and then he will be confined to his cell again.

    The warden may choose the same prisoner more than one time and he will be choosing completely randomly. But at a certain point of time, everyone will have visited the switch room. And at any time, the prisoners may declare that everyone has visited the room at least once. If they will be true, they will be set free but if they will be wrong, they will be killed.

    The warden gives them an hour to plan any kind of strategy and then they will be confined to their respective cells and will never be allowed to meet. What strategy can help them be free?

  • The Scoop
    Tristan’s sister Angela and her four friends love to share their most recent diary entries with each other at sleepovers. This last sleepover, Tristan was able to snag each of the girls’ diaries after they fell asleep. He flipped through them and found that each girl had a different crush, a different favorite shade of nail polish, and a different preference in ice cream flavors – and each of them had a big, juicy secret! See if you can figure out what he learned about each of his sister’s friends – and his sister.

    The Choices
    Girls: Angela, Mandy, Savannah, Alyssa, and Lily
    Crushes: Josh, Noah, Luke, Ben, and Sam
    Nail Polish Shades: Lavender, Lime, Banana, Sky, and Crimson
    Ice Cream Flavors: Rocky Road, Rainbow Sherbet, Cookie Dough, Reese’s Peanut Butter, and Raspberry Cheesecake
    Juicy Secrets: Still sleeps with a blankie, Loves lima beans, Hates Justin Bieber, Is really into cars, and Wants to be a lunch lady

    The Clues
    Tristan read five different entries for January 7th. One said, “Noah said, ‘Nice hair, Savannah,’ and I felt special.” Another said, “My nails are purple again, just like I like them.” A third said, “I wish Luke would look at me.” The fourth said, “I lost my beloved blankie this morning.” The last said, “I’m dying for some more of that rainbow sherbet.”

    “January 8th. Dear Diary, I accidentally chipped one of my perfect, lime-green nails today while doing my daily private anti-Justin Bieber ritual.”

    “January 9th. Dear Diary, Josh caught me examining his awesome antique Chevrolet after school today. I guess I was kind of hoping he would.”

    “January 10th. Dear Diary, Angela was writing a love note today. I tried glancing over her shoulder, but all I caught was the second letter of its recipient’s name, which looked like either a U or an A, and something about being a lunch lady before she yanked it away.”

    “January 11th. Dear Diary, I hope Sam likes the color red…I also hope he doesn’t mind girls who still sleep with blankies…”

    “January 12th. Dear Diary, I think it’s funny that both me and Savannah like nail polishes that are named after fruits. Love, Alyssa.”

    “January 13th. Dear Diary, I saw Sam eating Reese’s Peanut Butter ice cream yesterday. Could this be a sign that we’re meant to be? Love, Mandy.”

    “January 14th. Dear Diary, I just noticed that the name of my favorite shade of nail polish has something majorly in common with my name, and Alyssa’s favorite shade starts with the same letter as her crush’s name.”

    “January 15th. Dear Diary, The girls were over at my house last night, and someone flicked cookie dough ice cream at me. It couldn’t have been Angela, who will only eat raspberry cheesecake ice cream, and Savannah was in the bathroom…”

  • A king wants an advisor and comes to ask the 3 wisest sages.

    He blindfolds them and put the hats on their head. Afterwards, the king takes off their blindfolds. He tells them that their hat is either blue or white. He tells them that whoever can deduce the color of their hat will be his next advisor. Also he tells them that at least one of the sages will be wearing a blue hat. The sages can all see each other’s hats except of course, their own. Sage A sees that the other 2 are wearing blue hats.
    For hours no one spoke, then Sage A stands up and tells the  king the colour of his hat. What color is it and how does he know?
