Awesome game! My kids can't get enough of this, even though all of them are utterly confused every time we attempt it :-P
We played this game with 30 of our teens in our lounge upstairs - it was absolutely hilarious! We cut the response time down to zero - kids had to shout out a name instantly which really added to the fun! Tip - make sure you know who is on your right and left, and remember your own name too!
