NEW GAME (420983654) - blackhole98 [1.0] vs. Arizonaboy [0.0] (10 0 rated) (win: 13, draw: 4, loss: -4)


Does anyone know what the number highlighted in red means? I hadn't really ever given it much thought, but tonight my brother pointed it out to me, and I realized I had no idea what it was. Thanks in advance!
