For me, it is DE Simpsons. That game just kicks my rear end.
I've owned it for quite a while, and only have achieved 3 ball multiball maybe four times.
Also, the outlanes are wicked, and the kickback is dangerous and almost impossible to relight.
How about you?
RBION. Took me a long goddamn time to get to Atlantis, that's for sure. The ball times are pretty long mind you, but those letters can be a bitch to get.
Dirty Harry has a couple parts that are harder than hell for me though i wouldn't call it a tough game. Trying to complete the "shoot out" is brutal for me.
I only own 5 pins and I can dominate on all of them, but I still can't complete the spider wheel on my Scared Stiff.
BSD regularly kicks my ass.
BSD and 'Flash Gordon'.
Hey,
I'd have to say for all intensive purposes, The Shadow. I really enjoy the game, but keeping a couple of balls going while simultaneously playing the Battlefield in The Final Battle is rough. I would kinda sorta put The Simpsons Pinball Party in there, but I find it difficult more by the amount of stuff you have to do as opposed to what you actually have to do. None of the shots in and of themselves are particularly difficult, but the fact that there is SO much to do in a game to get to the end of it makes it hard. And Pin*Bot is a drain monster. Those would be the three I'd put in there.

All of mine. The only one I have beaten is Corvette, and I haven't come close since. I've gotten to the Final battle on Shadow once but couldn't beat it. Xmen right now is impossible IMO. Valinor will probably forever be out of my reach. I was two venom shots away from super hero mode on SM. I think AC/DC will be doable if I focus on completing songs as opposed to points.
Quoted from jayhawkai:
I500 are tough though.
what were you trying to achieve? High score, modes, position in race or laps completed?
Quoted from JesseB:

I've never been able to complete all the modes, nor finish the race or anything (that I can remember). I'm always going for a mix of modes and multiball.
Gottlieb Majorettes. I'm sure all will agree that those #5 bumpers below the flippers are a real challenge!

Mata Hari by far. I have had balls where i scored 400,000 followed by a ball where I scored 10 points. Too cruel!! Of the modern games that I own, I would have to say ACDC. Every time i build a big song jackpot, I drain. Had it up to almost 40 million once.....

This.
I've basically owned everyone of these SS games, and Flash Gordon beats them all. If your not listing that, you've never played one. In dot matrix era, bram strokers with lightning flippers is tough. Blows every dot matrix away with equal settings. Em's are different beast. Todd

RBION. Only game I can think of that I have a lot of time on and that I can't consistently conquer. I still have STTNG and consistently dominate it, I had Shadow for only a few months and could get to the Final Battle multiple times in a game...but RBION...man. So deep and challenging, the game is really amazing. Can't wait to get the gameroom done so I can set her up again and take some more shots at it.
Quoted from vid1900:
F-14
Tron a distant 2nd.
Well, you have a point about F14. I've killed Yagov several times, and got multiball on many occasions, but I have yet to put my initials on the default HS table...
You may have bested me.... F14 is a bitch.... 
2 of the 4 pins I currently own I also consider to be 2 of the toughest of any of the hundreds of titles I've played, which is part of the reason why I wanted to own them.
Judge Dredd & BK2K.
A baseball could drain between the flipper gap on JD.
Tales from the Crypt. Can never get to the Jam
Quoted from LesManley:

Agreed. You can get 3-4 letters on the first ball and think you're going to coast through it...then wam bam it's over...like WTF just happened?

Yep!
Or plunge 3 times, and drain 3 times, on missed skill shots.. WTF..
The outlanes have magnets in them, i dont care what anyone says !
Was gonna post earlier on how much i can hate this game, even though i love it.. 
X men since it is not a finished game. I have to take the glass off, and I feel to finish would be impossible at this point, if it was a finished product. Hard to control the ball or balls since it is a fast layout. Love its flow.
Can't wait for the update. Loved the lay out. Loved it enough to sell TOM to buy it. I am a one pin owner at this point.
