580 is where i capped off tonight!! Live on Instagram of all places. LOL Using RetroN 77 with original paddles.
If I had any tips, here they are.
1. On your first few passes just bomb away, as soon as you see your bomb hit the boulders fire off another. Usually you can keep up with the computers score that way.
2. Once the boulders start becoming fewer be selective with your shots. There is not time limit here so take your time and fire away when confident.
3. If you see your shot is not going to hit anything you can stop it buy firing off another. I do this until I see one of my shots are lined up with a boulder. This is the best way I have found to stay in the game longer.
Hope this helps at all.
