Title says it all... Lower the amount of spheres to 6. Last round there was always 1 sphere barely filled (it averaged to 2-3 with only 3 peeps). Would be better for the game to start the game with only 6 spheres and increase the slots if all 6 have been completely filled.

As things are now this round, the person who gets placed in 1:7 will already be royally screwed cause he'll end up all alone.
