More Middle Schooler Online Game help

[niq]

Skribbl has worked pretty well as a break from Math Team practice, but some of the kids are getting tired of it. Does anyone have any good suggestions for a virtual game? A math-free game is probably better, they're getting plenty of practice already!

I'm looking for something they can play in about ten minutes.

Kahoot quizzes? I think there is a library of free ones...
