New Owner Here!
Just got the game set up yesterday - no problems really, except for one:
It's very hard to get the ball up the right ramp, usually the ball goes up the ramp and sort of rattles at the top like it's getting caught by something, but I don't see anything blocking it. Maybe the ramp needs to be realigned, but I'm not sure what to adjust. If the ball goes up more slowly it usually makes it around the bend.
This can happen if the ramp is misaligned. The ball goes up the first (lift ramp) piece then hits the lip of the main plastic ramp. It bounces up into the rubber stop that fits to the back of Drac's coffin end cover. When the ball goes up more slowly it doesn't bounce as much and misses the rubber.
There are three hex posts supporting Drac's coffin, and believe it or not they are all different (tho very similar) lengths. It's really easy to get them mixed up when shopping the pin and you end up with a lip at the top of the lift ramp.
Have a look at the top if the lift ramp and if its higher on one side than the other it's likely the hex posts are mixed up
