* Save often when you're in a city; the timed puzzles that give you
  bonus tokens are often difficult, and if you've saved before you 
  get to those puzzles, you can keep trying to solve them until you 
  get it right. 

* Save as many of the Free Puzzle tokens as you can. If you are
  stumped by the Trickster puzzles, you will need three of these 
  tokens to get the game to automatically solve them for you.
