Quoted from AlexF:I thought Royal Guard was pretty tough. Just easy enough to beat once in awhile. Kept me pushing the start button for the few months I had it.
The other one that I found maddening was Quick Draw. Not a wedge head but those drops are a sucker shot that would infuriate me. The only game I've ever owned that actually raised my blood pressure while I was playing.
RG was released in 1968. But agreed, it can be hard. The slingshots, when the ball gets going side to side, are definite side drain makers.
Chris, I doubt you'll ever roll RG. I've only gotten it above 6000 points a few times. It's just not a game that has high enough scoring to allow it. Everything down low is 50 points max, except the side drains and middle drain when lit, but you can only get a max of 2500 points from those along with a lost ball.
If you score over 5000 on RG, you've had one hell of a game.
The 70s wedgie I've found the hardest is Jacks Open.
