15, though it varies. We're all extremely awesome at it; we're just not very good at hitting the board so it takes awhile. Once we couldn't even reach fifteen and just had to quit at, like, ten. That was when the younger kids were playing; like the five-year-old who couldn't even throw it far enough to reach the board, much less aim.

Lol. Awesome. I play with my cousins - their around 19 - and a guy cousin my age and we finish in like five minutes when we go up to 21. We've been playing for a long, long time...
