Slot machine technology has evolved over the years. The mechanical version, called “reels”, has almost disappeared in favor of slot machines controlled by computers.

The game has remained the same: the player pulls the lever or activates a button to trigger the rotation of the reels (generally between three and five reels) which present a series of symbols. The player wins if a combination of symbols (or identical symbols) is made on one or more of the paylines.

In this article, we will find out what activates the spinning of the reels in modern slots as well as in old mechanical slots. We will also look at what determines the odds in slots and the different variations of slot machines .

Mechanism of slot machines

The classic slot machine works with 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 doktorjudi 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.

We present a simplified version of a mechanical three-reel slot machine on a central shaft. The central shaft also supports three notched discs which are connected to the three rollers. A second shaft under the central shaft is made up of stoppers and a pusher, a metal part made up of three paddles. The pusher paddles are aligned so that they can push the notches of the discs.

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 begin to spin doktorjudi ewallet. They stop at a point, then the gain drops if there is a gain.

These mechanical slot machines were replaced by electric machines which operated on the same principle. In an electric machine, the rollers are actuated by motors and the stoppers are generally activated by solenoids, but it is basically 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 payouts, 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.
