Poker machines are there to make money for venue owners, not provide wins for players.
If not, the machine just continues to generate outcomes until the button is pressed again. If the machine determines a win, credits are paid. It then randomly determines the position of the symbols on the video display to produce an outcome, which is completely unrelated to the previous game's outcome. It does this continuously, every second, all day and night. The next second it generates thousands more possibilities. When the button is pressed, it randomly picks one result from thousands of possibilities. Each gaming machine has a built-in computer program that randomly generates thousands of possible outcomes every second.
