There is only one game hint that I can remember (other than the 2013 one mentioned above) that actually gave teams a possible advantage with robot design: 2009 Game Hint #2, which was a cryptic riddle including cities in the US, and teams figured out sooner or later that it referred to ice. Now, more people on the forum were worried about how the competitions were going to freeze and maintain ice (obviously they used regolith instead), but teams could have feasibly worked out the physics behind low-friction surfaces. But that's it.

All other game hints that I recall only hinted at the name or other vague clues that are never any actual help to teams.
