Al, it's used during fights to activate that Plinko style game on the right where you either nudge it into a Power Shot (shooter lane), drain, or Throw Any Punch to Win (right inlane). It doesn't often go through there but when it does, it's a cool little side game! If you happen to be in a Ca$h fight, and have a Smart Punch in the bank, then it can be huge to get the inlane...

I've owned a few CPs and played it on location when it was released. There are many tiny variations of parts changed, left off, post or no post, post capped where it appears on earlier release, inlane normal brushed steel style or most commonly is golden wirformed, etc! CP seemed a little rushed and though a nice complete game when taken for what it is, they left Crazy Bob out of the software and there are little bugs here and there!

U guys do realize it's a bare knuckles theme right?

Here ya go, cut n paste from above.
