is there a way to access only the difficult crypto's? :)

Thank God, no.

It's all randomized. If you're not competing, just keep reloading until you get one you'd like to solve.

Honestly, "difficult" is simply a rating of how many characters are in the puzzle. It has nothing to do with how complicated the quote is to solve.

Welcome aboard, and good luck!
