I copied the descriptions from the Google Search description of the sites.
abcya.com has quite a few games that are challenging and fun. I like Rotate & Roll. Go to the skills or strategies section for 5th grade. These games are not related to grade level skills... fun for all ages.
40xEscape
40x Escape is a logic game for kids in grades five and up. The goal is to escape each room by figuring out how to open the door.

Sugar Sugar 2
This game is like a custom sugar factory. You have to engineer a sequence that will deliver the materials through the right processes to the right destinations.

mathplayground.com has some fun games, but has commercials. The commercials I've seen are for appropriate things like cereal. Let me know if you see any inappropriate ones.
Run 2
This game requires a huge amount of concentration and memorization as you run (or skate) through the 3 dimensional courses.
