# Thread: Anyone feel like reverse engineering a puzzle?

1. ## Anyone feel like reverse engineering a puzzle?

So here's the story:

After my puzzle at Geocaching.com, ByrnedFish posted a puzzle too. I have the answer, but I don't have the method. He's declared me the winner, but the method intrigues me. Anyone want to give it a shot?

Don't click the spoiler if you want to play all the way through.

The real trick is the ordering mechanism...
T\$ and reputation points to any good insights into the ordering mechanism.

2. No insights - just the obvious things in the image.
10 letters, 10 digits.
No direct consistent relationship between numbers and letters such as A=1.
Listing letters in alphabetical order and numbering provided very few connections (A=1, B=2, C=3). But wouldn't expect this to help as the problem is how to order the letters prior to shifting.
Spheres have dots on them - each section having the dot in the same place. Dots don't seem to give a direction for movement, unless shuffling has to be done within each section (4, 6, 6, 4).
Three pairs with letter/number, but it is unlikely that these pairs stay together. Move letters and numbers independently.
Tempted to move spheres as in a sliding puzzle, but no ideas about directions nor what arrangement to aim for (apart from numbers in numerical order).

3. assigning the numbers 0-9 to "palindrome"
(P=1, A=2, L=3, etc)
rotting the cipher letters

i assigned the number to the letters as follows:

C = P = 0
Z = M = 8
B = O = 7
E = R = 6
N = A = 1
R = E = 9
Q = D = 5
Y = L = 2
A = N = 4
V = I = 3

however, i have yet to find any pattern.

4. 10 is a good number to arrange the spheres as in 1-2-3-4.

There might be a way to place the first 10 spheres in one group and the second 10 in another one. Having both letters and numbers in both but always one of each in each distinct position. I am still trying to figure out if there is a logic order to do that, no luck so far.

One example of what I mean (that is no the solution) would be:

C
ZB
ENR
Q654

0
38
192
7VAY

Something else to keep in mind, the numbers could be 0 to 9 or 1 to 0.
Or maybe the numbers are ROT-5 (which would be the equivalent to ROT-13 for letters).

5. My thought is that they can be arranged into a pyramid in 3 dimensions. It all becomes part of the how. The 10 digits seem to be the base level:

Code:
```   0
1 2
3 4 5
6 7 8 9```
It's a matter of putting them in the right order, and using that order to pick the letters.

6. Wow, don't everyone post at once, now.

7. This is my post over at gc.com, right before I brute forced the solve:

Well, 20 will make a good 3D pyramid.
First thoughts:
If you form an ordering pattern with the digits 0-9, you can order the letters.
Bottom layer:
Code:
```     0
1 2
3 4 5
6 7 8 9```
Second layer:
Code:
```     V
A Y
Q R N```
Third layer:
Code:
```  E
B Z```
Top:
Code:
`  C`
If you order the letters as you placed them on the pyramid, you get:
VAYQRNEBZC.
Not 100% sure where to go from there. I do have an idea.

8. Turn it sideways.
Place C Z B E along the bottom.
Then the layer of 3 letters N R Q
Then place Y and A beside each other.
V on the top.

V
Y A
N R Q
C Z B E

(I tried to format this, but it didn't work)

Start from C and read up the left, down the right, left, then up.
C N Y V A Q E B Z R
Shift
P A L I N D R O M E

9. Interesting. I like it...

10. It doesn't explain the numbers, but they might be distractors.
