Slot machines have evolved through the years, from the first mechanical machines to the modern ones. However, the basics of the game have not changed. In the early days, slot machines were merely designed to make money, and the prize was candy instead of cash. However, the strategy was similar to modern machines, in that the odds of winning were not proportional to the amount of the prize. As a result, slot machines became very popular and today they are the most popular form of gaming in many casinos.

Modern slot machines use computers instead of gears and mechanical components. However, they look like their mechanical counterparts. They are still based on the same principle, but their movements are controlled by a computer instead of the spinning reels.
