Why do you say that?  Steve explicitly asked about modifying his
program so it will continue the game until the user chooses to finish.
 As far as I can see your program does not do that.

Granted, you could do that without an explicit loop by using recursion
or maybe even "retry".  Still, conceptually it's still a loop even if
you use another (inferior in this case because more complicated)
technique to implement it.

You are making things unnecessary complicated here.  Instead you could just do

ruby 'o.rb'

by adding a line "psychic_test" at the end of the script - or even
better: get rid of the method completely.

Kind regards
