Paint Twister... College just got a little better! We used acrylic house paint, but next time, I highly recommend using washable kid paint (so much less of a pain to wash off). For every 10 people, one pint per color should be fine to cover two games. Also, we used plastic paint tarps although a lot still got on the grass. In any case, this made for such a great RA program and just a fun time in general!
