There are a few OXPs which set puzzles and riddles, apart from the more complex Missions.

Try working out where to buy the more über-lasers from New lasers for example. Or where to buy and sell the various items in New Cargoes.

But for a real puzzle, embrace the Dark Side and try and work out why something in the game does not work properly when you have 248 OXPs loaded and there are no clues anywhere as to why it has all gone perfectly pear-shaped!
