One day, while hiking in the Jungles, we discovered a place hidden inside the woods. It seemed like it was sitting there quietly for some years now. We approached the gate. A friend of mine knocked on the door. There came a voice -

That's it. Nothing else. Every time we knocked the door, the same voice said the same thing again and again. Finally, we decided to crack this code.

I will keep the mystery for you to solve. We are already in. Do join us by cracking the pass code. Oh, here's the door.

And, here's what the transcribed note says -

   A               B             C              D             E           F
(1,2-2,1)      (4,1-4,2)     (5,1-5,2)     (5,1-5,2)      (5,1-1,1)   (5,1-1,1)
(1,2–2,2)      (4,2-5,3)     (5,2-5,3)     (5,2-5,3)      (5,2-1,2)   (5,2-1,2)
(5,3-1,3)     (5,2-1,2)     (5,2-1,2)      (5,3-1,3)   (5,1-5,2)
(1,3-1,2)     (1,2-1,1)     (1,2-1,1)      (5,1-5,2)   (5,2-5,3)
(1,2-5,1)     (1,1-5,1)     (1,1-5,1)      (5,2-5,3)   (5,2-1,3)
(5,1-4,1)                                              (1,1-1,2)



You won't need any confirmation for the pass code. But, in case if you do -

Xwrisikcjh! $\leftarrow$ Apply the pass code as key!

COPPER

We find this by realizing that

each set is a list of points to connect. Each "tile" has 5 columns of dots, numbered left to right as 1,2,3,4,5. Each column has a number of dots in it, either 1, 2, or 3, numbered from top to bottom.

Then ....

Connect the dots as listed, according to the numeric layout I described, but realize that each set of connections starts with the left-most side of the figure to be drawn — that is, 5-1,1-1 starts with the 5th column of a tile, and proceeds left to right so extends to the 1st column of the adjacent tile. Following the instructions thus given yields this:

Or, COPPER.

Using this as a Vigenere key,

Xwrisikcjh! -> victorious!

(Thanks to @Techidiot for a helpful hint in TSL, and to @MOehm whose comment confirmed what I gleaned from the hint by having already figured that out.)

• I think that the dots wrap and that 5 refers to the 5th column of the previous brick. Then you'll get slightly nicer letters. Jun 15, 2017 at 10:23
• Ahh. That was my next guess.
