Need to know all about slots? You’ve come to the right place! In this guide, we will
cover everything you 🗝 need to know about slots – from odds to reels to wins, get the
knowledge you need to spin like 🗝 royalty.
Slot machines are by far the most popular
casino game, having surpassed table games due to speed, ease, and accessibility. 🗝 This
is because slots are plentiful and can be found in ‘prime seating’ locations by casino
entrances, making them not 🗝 only cheaper and easy to play, but also highly
accessible.
At Caesars Slots, we put the reels and riches of great 🗝 rulers in the palm
of your hand – at work, at home, on vacation, and anywhere you have a mobile
🗝 device.
WHAT ARE SLOTS?
Slots are gaming machines that generate random combinations of
symbols on a dial, where certain combinations result in 🗝 wins. The odds of winning on a
physical slot machine is around 1 in 49,836,032. The average return-to-player (RTP)
rate 🗝 is usually 92-97%, with online slots having better payout percentages than casino
machines. Online casinos like ours have a paytable 🗝 in every game, where you can read
about payout rates, prizes, and bonus features for that slot. You can find 🗝 the paytable
for our slot games by clicking the “i” button inside that slot.
THE BIRTH OF SLOT
MACHINES
It’s widely known 🗝 and accepted that Charles Fey is the father of modern slots,
creating the Liberty Bell (or first “New Nickel operated 🗝 machine”) in 1887 in San
Francisco. Slots became an instant hit, and the inventor was able to open a production
🗝 factory to manufacture slots. These machines do not differ much from modern ones, with
similar reels and symbols.
DID YOU KNOW?
Slot 🗝 machines go by many names! “Slot machine”
or simply “slots” are American and Canadian English, while “fruit machine” or
“fruities” 🗝 are more common in British English. In Scottish English these are referred
to as “puggies” and in Australia and New 🗝 Zealand, you might hear them called “poker
machines” or “pokies”, though these are still the same type of gambling machines. 🗝 Slots
have also been called “one-arm bandits” for their large levers used to spin the earlier
mechanical slot machines.
Land-based versus 🗝 online slots
Simply put, land-based slot
machines are those that you find in casinos that you visit in person. Whether you’re
🗝 taking a weekend trip to Las Vegas or Atlantic City with friends or bigger trips to far
off gambling centers 🗝 such as Macau, the slot machines you play in casinos are
land-based.
Land-based slot machines go all the way back to 🗝 the late 1800s in San
Francisco, where they were first kept in store entrances to entertain people who were
passing 🗝 by. Early slot machines gave winnings in the form of chewing gum and golf balls
before cash prizes became common.
The 🗝 earliest slot machine technology was made of
mechanical reels powered by random number generators. As computer technology became
more advanced, 🗝 computerized video slots have changed the slot playing experience for
the better. Game play has become richer and more diverse 🗝 with complex game themes.
Moreover, the jackpot potential is bigger because machines aren’t limited to how many
reels can physically 🗝 fit into the back of the machine.
As the years went on and
technology has become more advanced, slot machines have 🗝 become popular in casinos all
over the world. In many places, they have become even more popular than table games
🗝 such as poker and blackjack. Not only are they fun and entertaining, but they often
offer the opportunity for big 🗝 jackpots on small wagers without too much skill.
Online
slots have taken slot machines to the next level. First of all, 🗝 they offer players the
opportunity to play 24/7, whenever, wherever. It is not always easy to travel to a
casino 🗝 to play the slots, but players who are interested can now get the same
experience from the comfort of their 🗝 only living room. Whether you want to play on your
computer or phone, online slots offer a thrilling entertainment experience 🗝 from
anywhere in the world. Online slots are based on constantly evolving technology that
engage players with new changing themes 🗝 and fun features. Play experiences online are
more varied, which means that you’ll never be bored with the same thing 🗝 twice. That’s
why millions of people all over the world love to be entertained by online
slots.
POPULARITY of slot machines
So 🗝 why are slots so popular? For starters, they are
easy to play! Just insert or set your bet and push 🗝 the button or pull the lever,
depending on machine design. This ease also factors into the time in which it 🗝 takes to
play. It is possible to place over 500 bets an hour on a slot machine, and even more
🗝 when there are not many bonus activities.
Minimum bet requirements for slots also add
to their attraction. You can play a 🗝 short quick round with the chance at a jackpot or
huge prize for a lower fee than table games. Casinos 🗝 make their games attractive with
sounds, art, lights, and the exciting surrounding casino floor environment. Online,
slots are made with 🗝 the same environment in mind, with the option to adjust settings as
preferred. Slot designers build machines with player activity 🗝 in mind, aiming for an
engaging, stimulating, and overall fun experience where players feel a part of the
action.

TYPES OF SLOTS
CLASSIC 3-REEL
SLOTS
These 🗝 are modeled after the original (physical) fruit machines as traditional
3-reel slots. These basic slots are easy to play and 🗝 understand! To win, simply match
symbols along the top, middle, or bottom line. Some people use these to relax, unwind,
🗝 or reminisce. Traditional slot machines have physical reels as opposed to their video
slot equivalents, though classic slots can now 🗝 be found with either.
FLAT TOP
SLOTS
Flat-top slots have a fixed top prize or jackpot, also known as a cash pot
🗝 jackpot, standard jackpot, or non-progressive jackpot. These have a massive prize and
are the only types of jackpots that do 🗝 not grow or change in any way. The prize remains
the same between players and can be won by playing. 🗝 These jackpots may be lower than
those of progressive slots, though the chance of winning the jackpot is far higher 🗝 than
the chance of winning a progressive jackpot.
5-REEL SLOTS
5-reel slots, or video slots,
use a video to display 5 virtual 🗝 reels. These can be found in casino slots as well as
online ones.
Video slots typically have 5 reels, which allow 🗝 for up to 100 paylines
instead of just 1, creating more chances of winning. Paylines are winning combination
patterns on 🗝 the reels, and the more paylines you have the better your chances are of
winning. 5-reel slots include special symbols 🗝 like WILD and SCATTER to provide even
more ways to win. Be sure to read the paytable before you play, 🗝 to understand the game
you are playing. 5-reel slots become harder to understand and follow as they vary in
complex 🗝 ways to win and scatter symbol triggers.
BONUS FEATURE SLOTS
Bonus rounds are
unique features in slot games where you can win 🗝 without betting. These bonus rounds
might include a mini-game or free spins, usually triggered by lining up special symbols
such 🗝 as a WILD (substitutes any symbol on the reels to create a payline) or SCATTER
(allows for generous payouts, extra 🗝 rewards, or triggering a feature). Bonus rounds
offer a short and fast way to win extra payouts during a feature 🗝 before returning to
the base game. Some may require speed or skill, while others are up to chance or play
🗝 short graphics.
Free Spins are the most common and popular bonus feature. Once
triggered, wins stack as the reels spin without 🗝 taking more bets from the player. The
triggering bet is used in calculating the wins in most bonus features, so 🗝 the higher
you bet the better your bonus wins will be! Do you have a favorite type of bonus
game?
PROGRESSIVE 🗝 SLOTS
Most slots have fixed jackpot prizes that can be won or missed
without affecting the jackpot amount. Progressive slots have 🗝 a jackpot that increases
over time, as their jackpots are prize pools that rise each time the machine is played.
🗝 The value of the jackpot increases with every spin that is not won during a game,
essentially accumulating player bets 🗝 to return to them to a lucky winner. The odds may
be tougher, but the payout is sure to be 🗝 huge!
ONLINE SLOTS
Online slots are becoming
more popular each year, being preferable to some slot players over land-based ones. Is
there 🗝 any difference between physical and online slots? The answer is yes! Online slots
have more advantages than land-based ones, including 🗝 convenience and accessibility,
privacy, and better bonuses. Read more on why you should play online slots
Video
slots
This kind of slot 🗝 machine has more graphics and diverse gameplay than a classic
slot because of virtual animation. Many on the higher end 🗝 of the spectrum have quality
sound effects, graphics and animation, and have become the norm in many casinos online
around 🗝 the world – in addition to being the only kind of slots online.
Mega spin
slots
This feature means that a machine 🗝 has more than one set of reels in a single
machine – more variety, more entertainment. Mega spins slots are 🗝 made so that players
will never get bored of seeing the same content twice.
Slots multipliers
Multipliers
work to increase player winnings 🗝 by multiplying bets, line wins and total wins. The
multiplier symbol lands during either the base or bonus game to 🗝 signify the amount
which is multiplied.
Jackpot slots
Many slot machines feature different kinds of
jackpots, that can range from a few 🗝 dollars to a few thousand dollars. In general,
smaller rewards are easier to win, while larger rewards are rarer and 🗝 require higher
bets.
Multi-payline slots
Multi-payline slots are a product of technology’s ability to
add more features in slot games, which have 🗝 become more diverse in terms of animation,
sound and graphics. Multi-payline slots means that that there are multiple payouts on
🗝 winning combinations across reels. If a game has more paylines, then a player is more
likely to score a win.
3D 🗝 slots
3D slots are designed to make a user feel as if they
are having a 3D experience, without needing the 🗝 glasses. If you enjoy lots of
stimulation from sounds and animations, then this kind of slot is for you.
Vegas
slots
This 🗝 refers to the classic, unbeatable style of slot machines from Las Vegas.
Nowadays, many online slots are designed to recreate 🗝 the Vegas experience for those
looking to enjoy it from the comfort of their own homes.
SLOT BASICS &
TERMINOLOGY
Slots PAYLINES
A 🗝 payline is a straight or zig-zag line that determines the
payout for a spin, based on the combinations of symbols 🗝 appearing on the line. Slot
machines have you pay your bet per line, applying it to each individual payline you
🗝 choose to bet on, whereas online slots such as ours take your bet as is and apply it to
all 🗝 paylines without having you pay for each line separately. Only active paylines
provide a payout for winning combinations, and with 🗝 us, all paylines are active!
Variable or adjustable paylines are those that allow you to choose whether to wager on
🗝 them or not and fixed paylines are those where you must bet on all paylines but give
you the chance 🗝 to win a larger payout, which is why they are sometimes referred to as
all-or-nothing games.
Slots with more paylines provide 🗝 more opportunities to win, so
check the paytable for each slot you play to know your chances. Every time you 🗝 spin,
paylines with winning combinations will flash on your reels to show you how you won.
Each hit is then 🗝 combined to give you your payout.
Our slot machines, as well as those
in casinos, use a Random Number Generator (RNG) 🗝 to create a random output of symbols
even when no one is playing the machine! This means that the resulting 🗝 combinations are
truly random and unpredictable, ensuring fair gameplay. Every player has the same
chances of winning.
NEAR MISSES
You need 3 🗝 scatter symbols to trigger a bonus event and
spun one… two… and the third is just off the reel! So 🗝 close… right? This may be the
case, though the reality is that this near miss was probably one of the 🗝 many that
happen as a part of the game’s design. Slot manufacturers build near-miss elements into
their reels to balance 🗝 out the game’s payouts and engage players with a tempting win
they could have had.
FALSE WINS
False wins are more frequent 🗝 with modern slots and
become more apparent as more slot variations and paylines develop. False wins are wins
that are 🗝 lower than the bet placed, so if you were to bet one million coins and you won
175,000 coins, the 🗝 machine would still say “You won!” even though that spin ended in an
actual loss. Thes wins not only allow 🗝 you to spin more, but also add excitement to the
game. Old, single-lined slots had no reason to give false 🗝 wins, whereas now slots have
so many payout options that the machine shows you winning on certain lines and not
🗝 others, hence the small amount. If you could choose to bet on a handful of lines rather
than all of 🗝 them, false wins drop in frequency or all together, depending on the game
pays.
DEAD SPINS
If you spun and came out 🗝 empty-handed, you had what is called a dead
spin. Unlike winning spins with any type of payout, a dead spin 🗝 gives zero wins. The
more volatile a game is the more dead spins will occur; however, in such games, wins
🗝 will generally be substantially larger since they are less frequent.
WEIGHTED REELS &
REEL STOPS
Each reel has a set number of 🗝 reel stops, positions at which it can come to
a stop. Slot reels stop directly affects wins, making reel stops 🗝 critical in slot
design. “Weighted reels” are those in which weighting components have been added to the
reel stops. Weighting 🗝 components can be added to each reel stop, increasing the
relative frequency one reel stop will be used compared to 🗝 another.
Example: imagine
reels with spaces between symbols. A game could be designed to stop on a space with
more frequency 🗝 than on a symbol, which could stop with more frequency than a different
one. Weighted reels allow for an increase 🗝 in potential combinations and make some
scenarios more common than others.
Near-miss scenarios can be caused by weighting reel
stops next 🗝 to special symbols or by allowing two out of three needed symbols to show up
in place. These scenarios make 🗝 it seem like you almost made something happen, though it
resulted as a part of the slot’s design. Using weighted 🗝 reels can make top payouts
bigger, however, as they increase, so does the amount of dead and false
spins.
UNBALANCED REELS
Similar 🗝 to weighted reels, unbalanced reels use more or less of
a certain symbol on one reel over another to change 🗝 the chances of an outcome. Imagine
having three red 7s on one reel, another three on the next reel, but 🗝 only one on your
third reel. This unbalanced reel will give the effect of near misses when only two of
🗝 the symbols line up and it seems like an almost win. Unbalanced reels get more complex
with video slots and 🗝 slots with more reels. In games with stacked symbols and bigger
pays for five-of-a-kinds, unbalancing reels cause even more near-missed 🗝 wins. Like many
other near-miss opportunities, this drives up excitement and suspense. From a design
perspective, balancing symbols can help 🗝 a slot machine reach its payout target, while
the randomness in wins makes it exciting.
WILD SYMBOLS
Mutli-spin or multi-payline
slots often 🗝 feature many bonuses using special symbols as triggers. Wild symbols
substitute for all symbols other than the bonus icons (such 🗝 as scatters). These
sometimes multiply your wins or expand to fill the reel to increase your
payout!
SCATTER SYMBOLS
Scatter symbols, also 🗝 called Scatter Pays, are bonus icons that
pay wherever they land on a payline by completing a winning combination like 🗝 a wild or
increasing the payout for a spin. Three scatters usually trigger a mini game or bonus
feature that 🗝 provides free extra wins, such as free spins or respins.
