A very difficult game. I’ve never been able to complete more than 3 screens.
I recommend staying in the middle
Speaking as one grizzled veteran of 1980s coin-op, I've seen with my own eyes a teenager a couple of years older than me "roll the machine".
"Rolling the machine" meant scoring 100,000. At that point, the machine score went from 99,999 back to 0.
The way I saw it done, the player left 1 asteroid on the screen so as not to advance to the next wave.
The player then parked his ship near one of the corners.
After some time, a saucer would appear and the player would directly fire on it using the shortest route possible which, sometimes, was not in the obvious direction of the ship because of screen wraparound.
Wraparound meant, for example, that the shortest distance between the upper right corner and the lower left and right corners was northeast, not southwest.
Saucers always shot at the spaceship on-screen, and so would almost always lose.
We younger observers stood in awe when the machine score rolled over. [0]
We dubbed this "playing the corners".
