"...that coin-operated game where you roll a series of nine balls, one at a time, up a gently inclined lane that has a hump at the far end. The ball sort of launches off of the hump and then lands in one of several holes -- the farther away the hole is, the more points that hole is worth. It's a swell game, but the key moment for me is when I drop my coin in the slot, which releases the nine balls down a ramp -- the balls are all released at once and proceed down the ramp in unison, one after the other, so they all come to a near-simultaneous stop when the bottom ball reaches the base of the ramp, which produces a spectacularly satisfying Click! sound that resonates throughout the room. The appeal of the click (which is actually comprised of eight separate and distinct mini-clicks, which are separated by a nanosecond or so as each ball collides with the one in front of it) is hard to describe, but it's one of those exquisitely perfect noises that's exciting and comforting all at once."
