Initially, land casinos installed slot machines
as a diversion for casual slot machine players. That is a
little bit of Slot Machine
History. Unlike traditional casino table games (such as
blackjack or craps), slot machines don't require any gambling
knowledge, and anyone can get in the game with a minimum bet.
This business concept proved to be a huge
success -- slot machines eventually become the most popular
and the most profitable casino game in the world, bringing
in more the majority of the annual casino gaming profits in
the United States.
This is How Slot Machines Work.
The base technology of the slot machines has
also changed a lot over the years. The classic mechanical
iron and wood designs have been almost completely replaced
by computer-controlled slot machines. But essentially the
slot game has remained the same. The slot machine player pulls
a handle to rotate a series of reels - typically three, that
have pictures printed on them. Winning or losing is determined
by which pictures line up with the slot machine pay line,
a line in the middle of a viewing window. If each reel shows
the same winning picture along the slot machine pay line,
you win (certain single images are sometimes winners as well
- read the instructions before you play). The payout -- depends
on which pictures land along the pay line.
How Slot Machines Work
- Classic Slot Machine
The classic slot machine design works on
an elaborate configuration of gears and levers. The central
slot machine element is a metal shaft, which supports the
reels. This shaft is connected to a handle mechanism that
gets things moving. A braking system brings the spinning reels
to a stop, and sensors communicate the position of the slot
machine reels to the payout system. A coin detector initially
registers that a coin has been inserted and unlocks a brake
so the handle can move.
Conventional mechanical slot machines eventually
gave rise to electrical machines that worked on similar principles.
In an electrical machine, the reels are spun by motors and
the stoppers are generally activated by solenoids, but the
slot machine game basically plays out the same way. Electrical
machines have more sophisticated money-handling systems, like
those you might find in a vending machine, and flashier light
and sound displays.
In both types of systems this is How Slot Machines
Work, once the reels have come to a stop, the
slot machine needs to read whether the player has won or lost.
Now, we'll examine some systems for making this determination.
How Slot Machines Work - Payout
There are many different payout systems used in slot machines.
In one of the simplest designs, a slot jackpot is detected
by measuring the depth of notches in the discs that drive
the reels.
When you insert a coin in this slot machine, it falls into
a transparent case. The bottom of the case is a movable shutter
that is connected to a metal linkage. Normally, the linkage
holds the shutter closed. But when the slot machine hits the
jackpot, the third stopper shifts the linkage up, opening
the shutter so the coins fall out of the machine.
Normally this is How Slot
Machines Work, there is no real secret. Slot machines
have more elaborate versions of this design in order to pay
out partially on certain combinations of images and pay out
completely on the slot jackpot combination.
How Slot Machines Work - Modern
Slot Machines
In the past 20 years, electric slot machines and fully mechanical
slot machines have both been replaced by computerized slot
machines.
Most modern slot machines are designed to look and feel like
the old mechanical slots, but they work on a complete different
concept. The outcome of each pull is actually controlled by
a central computer inside the slot machine, not by the motion
of the reels.
Even though the computer tells the reels where to stop, the
slot machine games are not pre-programmed to pay out at a
certain time. A random number generator at the heart of the
computer ensures that each pull has an equal shot at hitting
the slot jackpot.
Computer systems have made slot machines a lot easier to
handle. Slot machine players can now bet money straight from
a credit account, rather than dropping coins in for every
pull. Slot players can also keep track of their wins and losses
more easily, as can the casino operators. The operation is
also simpler in modern slot machines -- if they want to, slot
players can simply press a button to play a game, rather than
pull the handle.
One of the great advantages of the computer system for slot
machine manufacturers is that they can easily configure how
often the machine pays-out (how loose or tight it is).
Let's see how the computer program can be configured to change
the slot machine's odds of hitting the jackpot. In a modern
slot machine, the odds of hitting a particular symbol or combination
of symbols depends on how the slot machine virtual reel is
set up. Each stop on the actual slot machine reel may correspond
to more than one stop on the virtual reel. Simply put, the
odds of hitting a particular image on the actual reel depend
on how many virtual stops correspond to the actual stop.
This is How Slot Machines Work
- A modern slot machine's program is carefully designed and
tested to achieve a certain payout amount. The payback percentage
is the percentage of the money that is put in that is eventually
paid out to the slot machine player. With a payback percentage
of 85, for example, the land or online casino would take about
15 percent of all money put into the slot machine and give
away the other 85 percent.
How Slot Machines Work - Variety
of Slot-Machine Designs
When you hit the slot machines in a land or online casino,
you'll have dozens of slot gaming options. Slot machines come
with varying numbers of reels, for example, and many have
multiple pay lines. Most slot machines with multiple pay lines
let players choose how many lines to play.
For slot machines with multiple bet options, whether they
have multiple pay lines or not, slot players will usually
be eligible for the maximum jackpot only when they make the
maximum bet. For this reason, gambling experts suggest that
slot machine players always bet the maximum.
Usually slot machine variations are only aesthetic. Video
slot machines operate the same way as regular machines, but
they have a video image rather than actual rotating reels.
When these games first came out, slot players were very distrustful
of them; without the spinning reels, it seemed like the slot
games were crooked. Even though the reels and handles in modern
slot machines are completely irrelevant to the outcome of
the game, manufacturers usually include them just to give
slot machine players the illusion of control.
Above are only a few of today's popular slot machine variations.
Game manufacturers continue to develop new sorts of slot machines
with interesting differences on the classic slot machine game.
A lot of these variations are built around particular themes.
Oh, and one more thing - be careful with Crooked
Slot Machines; they are still around sometimes. Learn
how to spot them!
