In www.theIQchallenge.com you can play against a machine solving numeric and alfanumeric series, dominos and matrix test. I wonder if it is more based upon a large data base or some kind of algoriyhm. When I tried some of the numeric series, I thougt it was the first, but after playing with the matrix I´d bet it is the second... interesting.

wtf m8?

I'm guessing algorithm. At least if it is a database they aren't updating it automaticly when you enter the correct solution to a problem.

Im guessing db. They got some wrong answers there, and because on that i will send there a lot of wrong answer, lets see if i can shake it at all.
