> All pinball machines offer a replay to a player who beats some specified score. Pre-1986, the replay score was hard wired into the game unless the operator manually re-programmed the software. High Speed changed all that. It was pre-loaded with an algorithm that adjusted the replay score according to the distribution of scores on the specified machine over a specific time interval. If you’re ever at a pinball arcade and you hear a loud wooden CLONK sound, that’s the “replay knocker”. It’s literally a solenoid that drives a piston into the case of the machine, and it’s intention is to let the entire arcade know “this guy/gal is really good”. Very satisfying sound! And no equivalent in video games.
