I suppose the only exception to this is hitting the, 'Spin,' button after a result in, 'Free Games,' simply because I don't feel compelled to sit there and watch every single individual line pay on a small win. I'd prefer to get my money's worth by at least watching the full revolution of the, 'Spinning,' reels. Given that such players are playing at a negative ER, it just means that they are losing their money faster. I should imagine that the house loves players who believe in such a way, or use the, 'Stop,' button for any other reason, though.
The video slot machine could instantaneously display the result of the, 'Spin,' without any actual, 'Spinning,' if it was programmed in such a way, of course, that would be far less entertaining. The reels, 'Spin,' for no reason other than effect. The only thing that you actualy, 'Stop,' on a video slot machine is the random number generator, which occurs after you have pressed the, 'Spin,' button, or, 'Max bet,' or what have you.
