TLW A Number Ring
@The-letter-wriggler, I’m just going through as many answers as I can find. I’ve got 53 so far!

Yes, it works fine on mine. I get the output of ‘NEHEIERHBBEAJBBKB’ for your text using the same key letter. I ran through all possible key letters and non seemed to be in English.

@Kford-academy
Re: A Number Ring, care to post them (without the grids) keeping 5 to a line for compactness in the forum.
There has to be a limit – I wonder what it is.

That’s really weird. What do you get if you decrypt this?
HHHCHIBIKIBEBGHCCBGFKEAEBBGJCJEKDJJCKKABFEECKCDFKDCDBIEEJGJEBDKIBFGIKADGBEAAJADDCKEBFHCFFGIJDKKHKGFGDGKJJDGGEIEJCDBKFGEGJGKKIEECAEDFGA

or this?
HEKGHEJKBKIBKECDIIGBECEAHEKGHEJKBKIBKECDIIGBECE

Madness, to me those don’t give anything meaningful when decrypted. Is it maybe an error in your encryption program. Maybe you are including the key character in the possibilities for each character? For the first one, I get ‘ILKEAGDNFMLA’. For the second I get ‘BDHGBCDHGB. Have you managed to decrypt your own messages?

KA-6 – Ridiculous Questions
Whilst I continue puzzling on with ‘TLW A Number Ring’, here is KA-6 for you to crack on with. Enjoy! (P.S. These puzzles have been taken – and slightly varied in some cases – from Chapter 10 of Martin Gardner’s ‘Mathematical Magic Show’, and the answers are generally a bit silly – so don’t overthink it!)

1. Which of these is more likely after four bridge hands have been dealt: you and your partner have two clubs or you and your partner have eleven clubs?
2. A salesman came into a store with his pet frog. He said, “I promise that my frog will repeat every word he hears.” The shopkeeper was confused, as after his conversation with the salesman, he noted that the frog never said anything. Nevertheless, the salesman told the truth. Explain.
3. Give at least three ways in which a thermometer can be used to measure the height of a tall building.

 

KA-6

1. I am clueless about Bridge, but my instinct tells me both scenarios are equally likely (for every arrangement where my partner and I have two clubs, our opponents will have eleven)
2. The frog is deaf?
3. One way – drop the thermometer from the top of the building and time how long it takes to reach the bottom; v^2=u^2+2as?

@Snakecharmer314,
You must be using a different RNG. Note that the last ciphertext I sent was really just pieces of your own ciphertext.
I generate my ciphertexts like this:
cat /dev/urandom | tr -dc ‘ABCDEFGHIJK’
because your ciphertext has maximal entropy no matter how it’s sliced, and therefore is also random.
That’s why I think it’s funny.

@Puttputt86, would you like to try again? The equation that you presented does not even include time.

TLW A Number To Find
=====================
The numbers at the four corners of the squares
shown, are related to the number within the
square in a special way. This same relationship
applies in each set of numbers and squares.

03==05
==14==
10==08

06==08
==08==
07==08

05==07
==03==
04==13

03==12
==27==
08==15

09==06
==06==
11== N

What number is N

TLW THE HUTCHINSON PROBLEM
==========================
You are to get a counter from the top left cell to the X at the lower right by
jumping the number of cells indicated by the cell the counter lands on.
Moves are orthogonal – left-right-up-down within the grid (no wrap-around).
The first choice will be either 2R or 2D.

2 3 3 2 1 4
1 2 3 1 2 3
3 2 1 1 3 3
1 1 3 2 3 4
2 2 4 3 4 2
3 4 3 3 2 X

for any postings use the notation: 1R-2U-3L-4D… the digit being the one landed on and the letter the direction from it.

What is the fewest number of jumps required.
What is the most number of jumps that can be taken (without repeating a circle).
How many solutions can you find?

(I have no specific answers to give, your feedback will be welcome)

@Puttputt86, all correct so far…

TLW A comPLEXmatrix
===================
What letter should be used to replace the question mark in this matrix of letters?
No one was able to solve this without the hint.

Here is the hint:
It is best to assign numerical values to the letters to solve this.
Now fill in with the following Row1,Column1 = 4, R1,C2 = 3, R2,C2 = 1.
To solve the problem you must discover a common mathematical rule that applies to each row.

X P L E L
P E L E P
P L X E X
L L L E ?
E E X L L

Answer giving the values of P L E X and therefore the letter of ?

 

TLW TRIPLET TRIP
================
Starting at any position, you are required to traverse the whole grid.
The rule being that you choose three different letters then repeat them to make the trip.

A B C A C A
C A C B C B
B B A C A B
A C B B A C

Show your trip by use of matrix index inserting 01..24
00 00 00 00 00 00
00 00 00 00 00 00
00 00 00 00 00 00
00 00 00 00 00 00

I wonder, how many such trips are possible?

 

[10degrees-admin]

I think the equation is x=gt^2 (discounting air resistance).
