A pretty young woman sits in a lovely garden, staring with single minded fixation at a set of tiles on the table. She thinks she can solve this puzzle, but it's the sort of thing that if she makes a wrong move she could screw up the long term strategy, and end up with an unwinnable game. To prevent that, the player needs to think several moves ahead. If she had an opponent, maybe she'd feel put on the spot while thinking this far ahead, but she has more fun against tricky faceless puzzles than tricky befaced people that do unexpected things and hold grudges. When it's just a bunch of tiles on the table, a puzzle to be solved, it's so much easier for her to *think*. She has all of the time she needs, the puzzle doesn't care. This way, no one has to lose. It's just a matter of figuring out how to win.

She just needs to figure out how. Hmmm, maybe if she moves this tile here, then...
