I'm super sorry if this has been posted. I skimmed this thread first and searched. Anyway, one of my friends poitned out, if you look at the 2007 gmae hint picture
http://www.chiefdelphi.com/forums/sh...2007+game+hint
and you look on the back of the bot you can see the reflection of a red light, a ,green light and a blue light.
What if different lights were like stop lights? You could only move a certain direction when a certain light was on? Tricky.
