The classic slot machine works thanks to a complex combination of levers, detents, and springs. The central element is the shaft, which supports the rollers. This tree is connected to a lever which operates the slot machine. A braking system stops the rollers, and a sensor communicates the position of the rollers to the payment system. A coin or token detector enables the lever to be released.
From the player’s point of view, it is much simpler: the player inserts a coin into the slot, pulls the lever, and the reels start to spin. They stop at a point; then, the gain drops if there is a gain.
These mechanical slot machines were replaced by electric machines that operated on the same principle. In an electric machine, the rollers are actuated by motors, and solenoids generally activate the stoppers, but it is the same principle. In either case, once the reels have stopped, the machine should determine the payout.
Determination of gain
There are dozens of ways to determine the payoff, the easiest being to measure the depth of the notches of the reel discs. Thus, the notch assigned to the jackpot is deeper than the other notches. Other systems exist, such as having a series of metal contacts on the rollers or using photoelectric cells that generate a current according to their exposure to light.
Computer-controlled slot machines
Most of today’s slot machines are designed to appear to be mechanical models, but they are controlled by computers. The computer uses motors to turn the rollers and stop them at a specific point.
Computer-controlled systems have made slot machines much more adaptable. For example, players can now use money directly in their accounts rather than dropping chips with each win. They can also track their wins and losses more easily.
What are the 3 colored lights above the slot machines for?
The yellow light, which can be activated by the player, is used to call a casino assistant. Red light indicates the machine is broken, while a green light indicates a machine requires manual payment.
