Freeware Puzzle Games

Are there any good non time dependent puzzle games for the PSP?

I am looking at getting a PSP, but I would like to be able to get some games that my wife and I can play together. Right now we're playing Professor Layton for the DS. Are there any games for the PSP that are at all similar? As in, a puzzle game that doesn't have the time component involved so that we can discuss the puzzle together?
