Oh yeah, maybe only one hole around the edge. But I just thought of something else...you know those plastic (or maybe wooden in some cases) puzzles where there's a maze and you have to navigate the marble/ball bearing through the maze, to get it to the other side? Maybe even something like that...where there's only one way out, but it's not so easy. And to be fair, since we're being fair now haha (or more fair anyway), maybe a camera is aimed at the puzzle on his chest, and a tablet is mounted above his head with the view of the camera so he can see how he has to tilt the tray to get the marbles out. Whatcha think of that idea?
