As a mathematician, I was excited by a one move game set in jail (a frequent location for logic puzzles) with a strong number theory puzzle. 
 
I immediately pulled out my number theory techniques, trying to remember the difference in the tau function between powers of primes and other numbers. 
 
Then I found the solution, and I was embarassed. 
 
It was a fun ten minutes.
