To get a really high score in the original Space Invaders there was a way to always get 300 points from the top spaceship. The spaceship was worth anything from about 50 points to 300 points and we discovered it was dependent on the number of missiles fired by the player. So if you counted your shots (and waited...) you could get 300 every time. With this in mind it was worth leaving a small cluster of 'invaders' on the screen for as long as possible and keep firing/waiting for the spaceship to get another 300 points. It meant the game took ages to play but I could play it like this through several screens of invaders to the point it kind of started again with them higher up the screen again.
