It's an even year, so we get a "ball" game. Probably kinda typical shoot to score. Possibly knocking into something (stone wall, if you believe the theme) rather than simply going through a hole? If I run with that too far I start imagining angry birds...
The endgame may involve transporting a minibot-like flag to a tower and raising it. FIRST really likes hints about endgames because they don't reveal much actual gameplay.

I'm unconvinced that the circles in the middle of the "field" drawing are actually solid structures. I certainly hope FIRST GDC didn't make the no-interaction mistake twice in a row....
I'm also unconvinced it's actually the field. It's more likely that this is a drawing of a game element, remember when the hint was a CAD model of one of the gates at the side of the field you walk through to place your bot? Super revealing...
