Slot machines’ technology has experimented many changes over
the years. At the beginning they had a mechanical design, and nowadays
that has been almost completely computerized. Although, the game
is still basically the same.
The reel slot machine has a central metal shaft connected to a handle
mechanism that holds the reels. That handle mechanism is the one
that gives things movement. A braking system is needed to stop the
reels after the spin, and also sensors to detect the reels position
so they can tell the payout. Of course, that a coin detector is
essential to detect that a coin has been inserted and that also
unlocks the handle so it can be moved.
Conventional and electrical slot machines, work on similar principles.
The big differences are that in an electrical machine, the spinning
happens by a motor and the breakers that stop the spin are activated
by solenoids. And of course, that they have more advanced money-handling
systems.
