Looking at the source of the #ingressportalsurvey: Experiment Concludes on Wednesday post, we find these codes:


[1] a2n7dnaefetnk3gnesw3
[2] e8hsb0e0ivzxgn8eb9c5
[3] jsduhgbha8cne9i4fbg2


Code #1

Observations

The reversed string doesn’t give us a nice keyword to work with in the middle. There might be another step involved.

Code #2

Observations

Running atbash against the code gives us:

v2shy0v0reactm2vy1x5

There is a keyword in the middle (react) with a weird set of characters surrounding it as the prefix and suffix.

[hint]

Many of those characters are v and x, which could be interpreted as Roman numerals.

[/hint]

Code #3

Observations

With 4 valid digits and lots of lowercase letters present, we should try transpositions first.
