Aight, so you got a buncha pins and you gotta battle it out against others. If ya stop a pin you get a point, and if ya knock a pin outta the arena that's two points. If you's knocked out, you keep going until you run outta pins. Whoever's the last one standin' or who's got the most points when times up wins.

[There's a lot more nuance but least that's the gist of it.]
