Project Euler has always seemed to be more about mathematical "tricks" than about imparting any kind of understanding of a computer science topic through a structured set of challenges. The only thing I found amazing was how little fun I have undertaking Project Euler challenges :^)

If you are looking for 'computer science topic' knowledge, I don't think you should search a site 1) geared heavily towards math and 2) seeks to challenge participants (unlike cryptopals, which provides a guide) in the first place.

That's a really good point actually. Perhaps Project Euler has a CS association where it doesn't really belong because it's often mentioned in CS/programming challenges threads, even if it's not intended to be the focus of the exercises.
