In the "bring murderous entities to your living room" sense? I really, really doubt it. Even if ghosts or whatever do exist, I don't really see how a little glass thing sliding around a piece of wood would get their attention.
Either way, I don't think it's a good idea. If you were to contact beings on the proverbial other side, what would you say, "hey dead guy, we brought you here to dance for our amusement and make the walls bleed!"? Can you honestly see that going well for anyone involved? If I were disturbed from my promised eternal rest by a bunch of bored kids, I'd rip their fucking heads off (given power to do that) and say
"THIS is what being dead is like, enjoy."
If there's no reaction, you're just playing the world's most "you cheated"-prone board game. Why not try scary stories and well-placed halloween decorations? If scaring is the goal, I think they'd get the job done just as well.
