Most Popular Slot Game Developers

Slot games are not created equally but you probably know that already. You’ve gone from one casino to the next and have seen how each casino can have completely different title or themes, types of slots and slot variations. The reason for this is simple. There is more than one software company developing slot games.

Some casinos work with one company, while others work with several. The casinos that work with more than one slot game developer often share some of the same titles – that’s why you can play the same slot game at multiple casinos – but then they work with developers that their competitors don’t. This gives the casino a unique library of slots (and other casino games) you won’t fine elsewhere.

This gives you as few or as many choices as you could possibly want. The problem is knowing where to play. What casinos have the slot variations you want to play? The themes you like? Or your favorite slot games?

By learning who the most popular slot machine software companies are and the types of slots they’re known for, choosing a casino will be much easier for you. Just find a casino powered by your favorite slot developers.

Best Online Slot Sites and Games on Mobile

If you join any of the slots sites we’ve selected, there is a large chance that it will also be accessible from a mobile device. This means you can play your favorite slots online real money from any location. Most mobile slots are also very scalable, meaning they cater to both Android and iOS device users. As a result, whenever you’re out of the house and want to play, you can.

To do so, you need to ensure you have a strong Wi-Fi or data connection, so you can play slots on mobile uninterrupted. The best online slots sites will come with their own mobile app to download, presenting you with an easier, more convenient way of accessing the games.

You do always need to be connected to the internet to play, though. It isn’t possible to download the slots to your device and play offline.

How to Get Started

If you want to play slot games for real money properly, we have outlined a few tips for you to follow. Utilize them to give yourself the best opportunities.

Choosing the Right Slots Site

When selecting a top slot website, you need to consider if it holds an official license and how good its reputation is with gamers. Furthermore, you should investigate the selection of slots it provides to ensure you get the most from it.

Creating an Account and Depositing Funds

After opening your casino account, you need to deposit money into it. Online casino payment methods like credit cards, e-wallets, cryptocurrency, eChecks and more are often available to use. Visit the cashier, choose your payment method and amount to transfer. Take note of minimum deposit limits, too.

Selecting and Playing Slot Games

Visiting the casino game lobby will allow you to see the various slot titles. Choose a slot that speaks to you. Make sure it offers an entertaining theme, an inviting RTP rate, preferably above the industry average of 96%, special features you like, and so on.

Understanding Slot Machine Features

Standard Symbols

Your standard symbols in online slots are usually fruit symbols, such as cherries, oranges and others. You’ll also see card icons, usually face cards, but also Tens and Aces as well. This is quite standard across the board, but these symbols can be used to mean something else.

Scatter Symbols

This feature does not have to follow paylines, but has been known to unlock free spins casino bonuses and free games. If scatter symbols appear on the screen, you can also win unique bonuses or be on your way to unlocking progressive jackpots.

Sticky Symbols

Sticky symbols can lead players to even bigger wins, as they can stay on the reel for many spins, instead of disappearing after one. They are especially good with free spins as they can generate even more of those, which means more chances to win without spending money.

Stacked Symbols

Stacked symbols are when symbols are literally stacked on top of each other, which means they can take up more room on the reels, therefore generating more ways to win. Stacked symbols can also vastly increase your payouts.

Autospin (Autoplay)

By turning on autospin, you can squeeze in more games in a short amount of time. Before selecting this feature, be sure to note how much you’re betting because the slot machine won’t stop until you tell it to and the bet amount will be the same each time.

Wild Symbols

If you’ve ever played online card games where the Joker or a certain card was “Wild”, the same rule applies here, too. When this feature is activated during a slot game, a pre-qualified symbol, like a Cherry or Diamond, along with a payline reel could help you match those five sevens or the like.

Multipliers

These symbols and reel combinations multiply your winnings by two, five, or even 10 times the original amount.

Bonus Rounds

Also known as bonus games, these typically pop up via a scatter symbol and can be a slot game within the slot game or be free spins, an exclusive video slot experience to help you maximize your winnings.

Common Mistakes to Avoid

Unlike other games that require strategic thinking and skills, like online poker, for example, slots are pretty basic; therefore, there are very few things you can mess up. To make sure you don’t fall into certain pitfalls when playing online slots real money, here is some guidance on how to avoid them.

Don’t Ignore Responsible Gambling Practices

Make sure you only play with money you can afford to lose and segment this into small units per bet. This way, you protect your funds and are less likely to experience problem gambling.

Don’t Chase Losses

The worst thing you can do if you lose is try to chase the loss and gain the money back. This leads to you wagering more money, depositing extra funds and sinking into a spiral where you’re spending money you don’t have.

Avoid Falling for Scams

There are online scam slots sites that are there to take you for a ride. The best way to avoid joining such betting sites is to ensure you sign up to a platform with an official license, which is regulated. All the slot sites we recommend are verified as safe and secure.

Don’t Forget Reading the Casino’s Terms & Conditions

You can learn more about how a casino offering online slots for real money operates from its T&Cs. This includes rules surrounding withdrawals, deposits, gameplay, bonuses, and so on. Informing yourself on these terms ensures you know how to proceed with online slot gameplay in the best way.

Slot Machine Glossary – Slot Terms and Definitions

Online slots are one of the easiest things to play in the casino but you need to understand all the terms and options before playing.

The goal for the slot machine glossary was to put together one of the most extensive slots terms documents online. I feel the goal has been accomplished. See if you agree when you finish reading.

Take a look and see if you can learn any new slot machine terms.

Action or Play – Action or play is the total amount of money wagered on a slot machine in a session or over a different time frame. Player’s club benefits are usually based on total action. When you put your club card in the slot machine it tracks your total play or action.

Bank of Slot Machines – A bank of slot machines is a group or row of machines sitting beside each other. Some of them may be physically connected, but they don’t have to be. The machines may share a common name or theme or they may be entirely different.

Basic Slots or One Line Slots – The simplest slot machines are one line or basic slots. Usually using only three reels, these slot machines are what dominated casino floors before all of the video slots became popular. Most of these machines have a simple pay out structure and only use a few symbols. Rarely will a basic slot machine have any type of jackpot because of the limited number of possible combinations.

Bet Max or Bet Max Button – Pay out charts are almost always based on a maximum wager. The bet max button automatically places a wager of the maximum amount based on your coin size. If the maximum bet is 10 coins per line and you set your coin size to 10 cents, the bet max button will bet $1 per line.

Bet One or Bet One Button – This button places a bet of a single coin when pushed. I don’t recommend using the bet one button because most of the top pay outs give a bonus based on a max bet. If you can’t afford to place a max bet find a slot machine that offers a smaller coin size.

Betting Units or Credits – A betting unit or credit is based on the size of coin you’re using and how much money you have in the machine. If you have $100 in the machine and are using a quarter coin size you have 400 betting units or credits.

Big Bertha Slot Machine – A Big Bertha slot machine is a marketing gimmick in the form of a huge slots game. Usually placed near a main entrance to the casino floor, these machines can have multiple reels (even more than normal slots) and take up as much space as a regular bank of machines.

Big Hit or Big Win – A big hit is simply a big win. One slots player may tell another they had a big hit after hitting a top pay out or jackpot.

Bonus Feature – A bonus feature is one of the new things that became available after the introduction of video slot machines. A common bonus feature is unlocked by hitting a certain combination of symbols and opens in a new screen. A bonus feature can be a different game entirely or include a mini movie or just be a different area with reels like the main game. Usually players have the chance at larger wins during a bonus feature than during normal game play.

Bonus Multiplier or Bonus Modifier – A bonus modifier or multiplier is a symbol or series of symbols that multiply a win by a certain amount. Common multipliers are two times (2X) and three times (3X) but they can be any amount the game is programmed for.

Branded Slots – Branded slot machines are themed after popular television shows or movie franchises. Examples include Wheel of Fortune Slots and Lord of the Rings slots.

Cashback or Cash Back – Cash back is exactly what it sounds like. Some player’s clubs offer cash back on slot machine play. Others only offer non cash comps, but if you look around you can find cashback slots offers both online and in land based casinos.

Certified Slots – Some casinos run promotions featuring certified slots. A certified slot machine has a payback percentage that’s been certified and is then advertised by the casino. Most certified promotions feature slots or groups of slot machines that pay out 97% or higher. Occasionally you may even be able to participate in a promotion that offers certified slots that have a 100% pay back percentage.

Coin In and Coin Out – Coin in is the total amount of coins or credits played in a machine and the coin out is the total amount of coins paid out of the machine.

Coins – Coins are the size of the base wager on a slot machine. In the past you could play with actual coins or tokens, but most slot machines today are played with cash or slots vouchers or tickets.

Coin Size – The coin size is the amount each coin is worth. Some machines only have one coin size but some allow you to adjust the coin size. Coin sizes include penny, nickel, dime, quarter, fifty cents, dollar, and five dollar.

Cold Slots – A cold slot machine is one that hasn’t paid out in a long time. Many players believe machines run hot or cold, but mathematically machines simply pay out the percentage that they’re programmed to pay out over time.

Comps – Comps are earned through a player’s club for playing slot machines and other casino games. Comps can include free hotel stay, free meals, free flights, cash back, coupons, special deals, and just about anything else of value the casino may give you in exchange for your play.

Credits – When you put money into a slot machine it’s divided by the coin size to get the total number of credits you have to play with. If the machine has a coin size of 50 cents and you put in $60 you have 120 credits.

Denomination – The denomination is the size of the coin for the slot machines. Some machines let you change the denomination but some have a set coin size.

Fixed Value Slots – A fixed value slot machines has only one size bet available. You can’t pick how many lines, coins per line, or the coin value. These machines aren’t as rare as many think. Some players prefer a simple playing decision and these machines fit the bill. All you do is put money in and hit the spin button.

Five Line Slot or Five Liner – A five line slot machine simply has five possible pay lines. This isn’t a term used often now because of the explosion of availability of 25 line and higher machines

Free Spins – Free spins are exactly what they say. Most free spins are part of a bonus situation or game or a multiplier or other special feature.

Hammer A Machine – Hammering a slot machine is a slang term used to describe playing a single machine for hours on end. The most common reason for hammering a machine is when a progressive jackpot is high and the player is hoping to hit it.

Hit and Run – Hit and run describes a slots player who plays a few spins on a machine and then moves on to the next machine. These players usually are looking for a hot machine so if a slot doesn’t hit in a few spins the player moves on until she finds a machine that hits a win in the first few spins.

Hit Frequency – Hit frequency is how often a slot machine pays out a winning hand. Some machines pay out less on a greater number of hands while others pay out fewer times but larger amounts when they do pay. You’ll find players who like both types of machines, but generally they like to win more often, even if the wins are smaller than on tighter machines.

Hold Percentage – The hold percentage is how much the slot machine keeps as a percentage of total play or action for the casino. If a slot machine pays back 96%, the hold percentage is 4%. This means that in the long run the machine earns $4 for every $100 that’s wagered.

Hot Slots or Hot Slot Machine – A hot slot machine is the opposite of a cold one. A hot machine seems to be paying out at a higher than average rate. Many players jump from machine to machine in hopes of finding a hot machine.

Jackpot – The jackpot is the top pay out amount on a slot machine. Sometimes the jackpot is a progressive top prize that climbs with each spin until a player wins it.

Line or Pay Line – A line is usually from left to right and is the plane or area where you need to line up matching symbols to win a pay out. You activate one or more lines on most slot machines and if a line isn’t activated you can’t win for combinations on that line.

Linked Progressive Jackpot – Some progressive slot machines are linked to other machines. Most of the time the machines are all the same brand, but they don’t have to be. This helps progressive jackpots climb faster because more machines are feeding the top prize. The machines don’t have to be in the same casino to be linked. Online casinos often offer progressive games shared by hundreds of different casinos.

Loose Slots – A loose slot machine is one that is paying out more often than normal, or one that appears to be doing so. Loose slots is another name for hot slots.

Multiplier – A multiplier is an amount a winning spin is multiplied by. Multipliers usually are associated with free spins, scatter symbols, or another special feature or symbol.

Near Miss – A near miss is when a symbol lands just above or below a line that would have made a nice pay out.

Nickel Slots – Nickel slot machines are ones using a 5 cent coin size. While you can generally play for only a nickel a spin, most of these machines require a larger bet size per spin to have a chance to win the top amount. The coin size is still five cents but you have to bet more than one coin per line and / or more than one line.

Nudge Slot – A nudge slot machine moves a symbol that’s close to making a winning combination the little extra it needs to line up for a win. This is just a gimmick on how a winning spin is displayed, but some players enjoy the thought of nudging the machine to make a losing spin a win.

One Armed Bandit – A one armed bandit is a term for a slot machine with a lever on the side. Many slot machines don’t have levers now, but in the old days they all had arms on the side you had to pull down to activate the reels.

One Liner or One Line Machine – A one line slot machine only has a single pay line. Fewer and fewer one line slots are available as multi line video slots games have become more popular.

Payback Percentage – Payback percentage is the amount of money the slot machine pays back as a percentage of the amount wagered through a machine. A slot machine that has a 93% payback percentage pays back $93 out of every $100 on average to the player. In the short run the percentage will vary a great deal, but in the long run it’ll average out correctly.

Pay Line or Payline – A pay line is a line where matching symbols must line up to match winning combinations listed on the pay table. Most machines have multiple pay lines that must be activated to be eligible to win.

Payout or Pay Out – A pay out is how much you get for a specific winning combination of symbols. For example, you might get a payout of 25 coins for lining up four matching symbols from left to right on any pay line.

Pay Table – The pay table is the screen or card that explains which matching symbols pay and how much they pay.

Penny Slots – Penny slots are set for a coin size of one cent. Rarely can you actually play for a penny a spin because you have to activate multiple lines and play more than one coin per line.

Primary Jackpot – A primary jackpot is the top paying jackpot on a machine that has more than one jackpot. Some machines have a secondary or group of secondary jackpot amounts.

Progressive Slot Machines – A progressive slot machine has a top payout that grows with each spin. Most progressive jackpots are tied to multiple machines so the jackpot grows quickly. A percentage of each spin is added to the progressive amount.

Quarter Slots – A slot machine with a set coin amount of 25 cents.

Reels – Reels are the wheels that spin inside the machine or appear to spin on the screen of a video slot machine. The most common machines have three or five reels, but other sizes are sometimes available. I’ve seen seven and ten reel machines, but they aren’t common.

Random Number Generator or RNG – The computer program that controls the outcome of the slot machine is called a random number generator. Each possible outcome has a number or numbers assigned to it and the RNG picks a number at random for every spin. A particular losing combination may have hundreds of numbers attached to it and the top pay out may only have one number assigned to it.

Scatter Symbol – A special symbol that can land anywhere on the reels and still pay out or unlocks a bonus of some sort without landing on particular lines. The symbol is scattered all over the screen instead of lining up.

Second Screen Bonus – Video slot machines sometimes have a bonus round that launches after certain combinations are hit. A second screen bonus is one that opens on a second or different screen from the regular game play screen.

Secondary Jackpot – Some slot machines have more than one jackpot. The highest jackpot is called a primary and all of the others are called secondary jackpots.

Select Lines – Used to select the pay lines you want to activate for the next spin. Most players either play the maximum number of lines or a single line.

Slots Club or Player’s Club – The slots club or player’s club offers rewards or comps for your slots play. The more you play the higher the possible rewards.

Slots Host – The casino employee who takes care of slot machine questions or issues is called a slots host.

Slots Schedule – A slots schedule is another name for a pay chart or pay out chart. Most players don’t use this terminology now.

Slot Machine Tournament – A slot machine tournament is when you pay a set entry fee and play for a set period of time for the chance to win cash and prizes. The players with the highest amount at the end of play win the listed prizes.

Sound of Rain – The sound of rain is an old saying that slots players used when actual coins were used in the slot machines. The sound of rain was the sound of coins hitting the metal tray at the bottom of the machine after a big win.

Spin or Spin Button – The spin button is used to start spinning the reels. The spin button replaced the lever on the side of the slot machine.

Streaky Slots – A streaky slot machine is one that players believe runs hot or cold in streaks. A machine is usually believed to run both hot and cold at different times if it’s streaky.

Symbols – The symbols are the pictures of different items on the reels of the slot machine. You need to line matching symbols up on an activated pay line to win. Symbols can be anything from a bar to an elaborate portrait. Popular symbols include cherries and pictures that match the theme of the slot machine.

TITO Ticket In / Ticket Out – Slot machines have mostly stopped accepting coins and use cash and tickets to accept money and pay out money. You may put cash or a ticket in the machine but when you cash out the machine prints a ticket. You take the ticket to the cage when you’re ready to cash out.

Tight Slots – A tight slot machine is one that seems to be paying out at a lower than expected rate. It may be paying out fewer times than expected or fewer coins than expected.

Total Bet – The total bet is the total amount of coins or money wagered on a slot machine for the current spin.

243 Pay Lines Machine – Some new slot machines have 243 pay lines, claiming to cover every possible pay line. They simplify things in one way, but if you try to figure out all the possible pay lines you’ll probably end up with a headache.

Video Slots – A video slot machine has a picture of reels on the screen, like a video game. You won’t find any actual reels inside the cabinet of a video slots game.

Voucher or Ticket – A voucher or ticket is the same thing I described in the ticket in ticket out section above. A ticket is printed when you take money out of the slot

Wide Area Progressive or WAP – A wide area progressive is one with slot machines from different areas connected for a single progressive jackpot. Any player on one of these machines can win the jackpot and all the players are making the progressive amount go up as they play.

Wild Symbols – Wild symbols, usually found on video slot machines, are used in place of other symbols to help you form winning pay line combinations. Some wild symbols offer a multiplier bonus when used in a winning pay line. See the pay chart on your machine for more details.
