I tried a few of them on my iPad and many have poor physics, on one of them you can't even shoot the ball Any suggestions?
My favorites are Last Gladiators (especially Knights of the Rose table), Pinball Dreams HD and Tristan Pinball. War Pinball is great too, but those others have more realistic physics. Also, Zen Pinball (the Marvel table) is coming eventually...
I’m not a great judge of pinball physics, but I’m liking Vampire: http://appshopper.com/games/real-pinball-hd-vampire I have a couple other favorites that I know are NOT realistic physics—they have their own gimmicks which are fun, but may not be for purists. (Like Undead Attack and Multiball Pinball.) P.S. If a game won’t shoot the ball, try holding on the spring and waiting—some games work that way instead of a drag.
