I learned how to play pinball on EM games. I will recommend a couple of titles for specific reasons. I list these in no specific order:
Gulfstream- This game is a hybrid Add-A-Ball/Replay model (Williams made several titles this way in the 70s). It features 3: Flippers and Inlanes (Italian Bottom). The inlanes light for an Add-A-Ball, so you can practice the Alley Pass to score this rollover. This is the game that I learned how to do an Alley Pass on. The top rollovers are great for nudging skills and the Tic-Tac-Toe feature is fun.
Flying Carpet- This game lacks inlanes, but the bottom is great for nudging. This is a tough game and I hated playing it when I was a beginner, but grew to appreciate it when my pinball skills got better. There is a fun shot off the upper “Special When Lit” rollover rubber ring that banks into the Pop Bumper area.
Sky Jump- Yes, I agree with the other posters above who endorse this game. I love the shot from the flippers through the “6” rollover. A lot of rollovers and nudging. 3" flippers and an Italian Bottom. Good Choice.
Gottlieb King Pin- Some people hate the huge side drains, but this is a volatile game. Great target shooting choice but lacks the nudging benefits of my other recommendations. This game has 3: Flippers and an Italian Bottom.
I think I will stop here. I can list several more if you want me to.
