Quoted from davewtf:To make sure the credits kept piling up, we sacrificed great games right after beating the previous first place score so we could more easily rack up credits.
Oh yes, this was a common practice for me and 'the gang' when we played Bally Star Trek in around '79, the game that got me into pinball! Ideally we'd get close to the high score and realise that the bonus would take us over it. At the point we'd drain the ball and as the bonus counted down we'd tilt the machine just after is passed the high score!! Bonus countdown was very slow on Star Trek, so it was easy to do
