On a real arcade game, what you don't see, are the side slots, where coins drop as they are pushed. So the appearance is, the money or the special prizes appear to be on the edge and will fall soon, when in fact, they move forward, very slowly. And on some, in the center is a wedge shape, so the coins go to the sides even more! Nitoce the lip on the edge, which makes a third way that coins will flow to the point of least resistance.

Any computer app or virtual game is a scam.
