Score, I would think. May be hard to keep track of balls added while playing a long game.
My goal for the aab's is to roll it and get the 100,000 light lit. Then it's 'beat', and I move on to another.
*my highest score on Big Hit was in the 90k's (written down at home), and my run count was 99. I wonder now if it was 'maxed out', or if that rolls too? You have me beat on Volley, though.
Nice score board!
