Well, everyone putes their cubes on table and then we scramble them all and you just solve as many cubes as you can. So it doesn't matter if it's your cube or not. Besides, the person who brought the least number of cubes, would always lose then.
Amusing. It makes me smile on the inside (and outside, for that matter).
I should try this with some of my friends sometime... Only problem being we don't have that many cubes... (Though I guess with the amount of people it could become reasonable)
