Knowing only that the side length of the small, white square is 3 units, can you determine what the side length of the yellow square must be?"

Don't quite get what the site is, but you did send me a few gawkers at the logic test. Thanks! No tries though, not yet.

Well, all I can say is call up your local neighborhood cards & comics store, or maybe a video game store (like GameSpot) and ask them when they will have Perplex City Season 2 cards available. Then, go buy a pack or two, and, as the players say, you'll fall down the rabbit hole.
