I tried to do that last time, it was a big failure. At least Kahoot doesn't allow you to do that, there might be a solution, but I didn't know it.
What was the problem exactly? I have taken part of multiple real-time kahoot quizes and the competition is funnnn.
Or OH OH OH, what about a skribbl.io custom session where we draw bitcointalk related drawings?
Mmm it can be fun, but I'm no good at drawing
