Full Circle

08 10 17 09 31

Place 24 pigs in these sties so that, no matter how many times one circles the sties, he always find that the number in each sty is closer to 10 than the number in the previous one.


Leave it to Lewis Carroll to come up with a strange puzzle like this.

Starting the circle at the northeast sty, you find that 8 is closer to 10 than 6. Next, walking to the southeast sty, you find that 10 is closer to 10 than 8. Continuing to the southwest sty, you find that nothing is closer to 10 than 10. Finally, up to the northwest sty, you find that 6 is closer to 10 than 0.

    I would love to have met Lewis Carroll! A writer and poet, photographer, mathematician, theologian, and silly person. That’s a pretty excellent resumé!

    Ah, I see now. Trying to solve it myself, I thought the numbers were supposed to ascend closer and closer to 10 no matter where you start and whether you go clockwise or counterclockwise. Of course, I found no proper answer.


  3. I understand why I am as inferior as I am really. That is what makes others famous

    A very clever puzzle! It took me a while to realise that “nothing is closer to 10 than 10” relates to wordplay rather than maths.
