It all started in 1891, somewhere in Brooklyn, New York with two men sharing a vision that would change the gaming industry forever.

It was at that time that Sittman and Pitt created a unique machine with playing cards distributed across five reels and one big lever that shuffled them. To play, you would have to insert a nickel aka a five-cent coin and pull that lever. If you could see a pair of kings, you would have a free beer. If you had the best poker hand - a royal flush - you would get a pack of cigarettes or more drinks depending on the rules of the house - that time, a bar more than anything.

During the same period, another man, Charles Fey of San Francisco, California thought of a much simpler version of the Sittman and Pitt poker machine and invented the first slot with just three reels that contained a total of five symbols. One of these symbols gave the machine its name: Liberty Bell.

More than a century later, Fey’s invention took over the world creating an entire digital universe of its own. 777slotsbay online casino has a very special place in this universe as it is home to almost a thousand of online slot games including:

  • Classic Slots

  • Video Slots

  • 3D Slots

  • Progressive Slots

  • Bonus Slots

If we also add a plethora of FREE Spins in the equation, then you’ll most likely realize 777slotsbay is the ultimate online gambling spot on all the Internet.

Heck, you don’t even need real money to play online slots, you can always play for fun before making any type of investment. Just make sure you read the contents of this page to best understand the online slots universe. You’ll find here all the information you can possibly need without any further lookups or time wasted on search engines.

It is all here, at your convenience.

Welcome To The World Of Online Slots!

Since the late 19th century and Fey’s days, the slot machine industry has greatly diversified starting with the brick-and-mortar casino boom of the 20th century and continuing with the online revolution of the early 21st century.

Today, you’ll find thousands of slots, all trying to lure you into trying them out. Most of them you’ll find on 777slotsbay online casino tidily grouped together into specific types so you can make the best choice no matter if you want to play online for real money or simply play for fun.

Classic Slots

Remember the humble beginnings of slots with Fey thinking of a simplified system with fixed payouts and three Bell symbols to top them all? These are the classic slots in a nutshell: online games trying to recreate the simplicity of the old Liberty Bell and Fruit machines.

Liberty Bell – First Three Reels Slot Machine made in 1899

Like the original, the classic slots have three reels and a handful of symbols. They are usually low-cost and a great entry point for the newcomers who want to make sense of this crazy spinning slot world. You may find classic slots with jackpot features but do not expect a whole lot of creativity in terms of paylines.

It’s all about keeping it simple, you know.

Video Slots

Video slots are the latest creations of the casino gambling evolution and revolution, for that matter. They are the most complex beast in this universe with five, seven, and yes even NINE reels which usually mean an unthinkable number of combinations.

With the reels comes a greater number of symbols, a variety of paylines - sometimes up to 117649 (Megaways Slots) plus one big payout table that orders all this ‘mess’ with prizes giving you BIG wins that could turn your life upside down.

Bonanza – Modern Megaways Online Slot

The number of video slots has greatly increased as the Internet went global over the last two decades or so. The computational power freed the slots from all the past limitations and now, millions upon millions of permutations and calculations made automatically in the blink of an eye for you to enjoy the best & spin the reels time and time again.

3D Slots

These are the latest additions in the online casino gambling world. With 3D slots, the symbols are not just simple images on a screen; they are amazing animations that will give you the impression the slot machine has come to life.

Stunning Animation in “The Slotfather” Slot by Betsoft

To catch your attention, game providers have developed many unique online slots with a backstory and some graphics to help the game reach its full potential. From wonderful animated backgrounds to awesome sounds, well-crafted 3D symbols, as well as expanding wilds… this is what you’ll find if you decide to browse this category. You’ll also witness the addition of new games specially prepared for upcoming festive celebrations like Christmas and the New Year, Easter & yes, even the arrival of the much-needed summer vacation we all need and deserve. All you have to do is keep a close eye on this category, all year long.

Jackpot & Progressive Slots

These online slots are named in this manner because they have one special feature that is the Progressive Jackpot.

The Progressive Jackpot is a unique payout that increases over time as the game is played more & more. The slots player usually doesn’t need a special combo to win the progressive jackpot; he/she just needs to play.

Mega Moolah Progressive Prizepool over 8 million USD

Basically, every time someone spins the reels at a slot machine, a portion of his/her bet is redirected to a prize pool that is the jackpot. As in the lottery system, the prize pool increases as time goes by & nobody cashes in the BIG win. When the jackpot is won, the prize pool resets.

To make the jackpot really worthwhile, many slot games are linked together and share a common prize pool. In some cases, you’ll also see different jackpot tiers, ranging from small to BIG real cash prizes.

Be sure to check this category and play the real money slot games for a chance to win the progressive jackpot.

Bonus Slots

Most of today’s slots have a bonus round that helps the player increase his/her chances to win. Usually, a bonus round is triggered when a special symbol like the scatter or the wild appears several on the reels.

Wild Desire Bonus triggered

The bonus round can include FREE Spins based on how many times the special symbol was present on the player’s screen beforehand, but is not limited to just FREE Spins. You can also earn special multipliers, win random cash prizes, or trigger some other neat features that could involve Wilds or other special-designed symbols.

It’s up to you to find out which feature do you like best by taking a look at this special online slot category.

Online Slots Under The Hood: Random Number Generators (RNG)

Browsing through the top 20 online slots above may leave you with some questions that need to be answered immediately. For example, what is this RTP? What about volatility?

Before explaining those terms though, we need to take a closer look at what’s behind a generic slot game that you can play for real money online.

Coin Flipping example of Random Number Generator

Nowadays, a cryptographic algorithm called Pseudorandom Number Generator (PRNG) - widely known as Random Number Generator (RNG) - does all the work behind the scenes when you spin the reels of your favorite casino real money slot. The RNG basically determines the outcome of a spin making permutations in the blink of an eye.

The RNG is the main factor behind the diversification of online slots to the point you can actually find almost a thousand such casino games on platforms like 777slotsbay. Digitalization and RNG helped the slot industry escape its mechanical limitations & gave the freedom it deserves. As a result, the 5-reel slots are the standard with the 6-, 7-, and 9-reel games becoming more and more common. Every time someone takes a particular slot for a spin, millions and millions of combinations are calculated in under one second, and what used to be unthinkable odds are now easily translated into payouts without any major fuss.

Online Slots Payout Explained: Return To Player (RTP)

Setting all the talk about RNG aside, slot players are much more interested in finding out specific information about the games they intend to play, for example how much can they expect to win given a long-enough timeline.

The online casinos & game providers, for that matter, have responded over the course of the last several years and made the RTP of each online slot public.

Theoretical RTP

RTP - the acronym for Return To Player - is a percentage that shows what a player can expect in the long run when he/she places a bet & spins the reels of a given slot.

As an example, the number ONE game in our top 20 most popular online slots, Bonanza by Big Time Gaming has an RTP of 96%. That means, on average, you can expect to win 96 cents for every dollar you bet, given a long enough timeline. Big Bad Wolf has the highest RTP from that list, giving you 97.35 cents for every dollar wagered, on average.

Actual RTP

Worth noting is that all these percentages presented to you by the casino software providers are theoretical. No one can guarantee you will actually receive for example 96 cents for every wagered dollar at Bonanza slot game, each and every time. The number can only be true if you play the game constantly, for a long period of time. (Millions of spins). As you play more and more, the possibility to reach that percentage will increase greatly.

Given a small sample size of spins, there is a distinct possibility the actual RTP will fluctuate away from the average. Thus, if you have a winning session, the RTP will be greater than 100%, based on your actual winnings. A losing streak will most likely translate into an actual RTP that is much lower than the theoretical RTP.

A Word About Volatility

Apart from the RTP, you also have to take into consideration the volatility factor which may be even more important than some theoretical percentage.

Volatility in online slots is all about the frequency of wins. To better understand the process, let’s imagine a game that gives you a cash prize of 5000x your bet and nothing major in between. In other words, you would win the cash prize every 5,000 spins or so. This is a classic example of a game with volatility over the roof even if the actual RTP is actually 100% and indeed, the cash prize is paid every 5,000 spins.

Dead or Alive Extremely High Variance Slot Machine

Now let’s imagine a game that only pays 2x your bet. With the RTP of 100%, you will win a small prize every two spins, which literally makes the proposition dull because of the virtually non-existent volatility. You won’t see such slots on 777slotsbay, don’t worry!

Therefore, a slot with low volatility like Gemix will give you the possibility to win smaller prizes more often. On the other hand, Book of Dead has all sorts of juicy combos that hands you BIG wins but much less frequently.

Don’t Forget Special Deposit Bonuses & FREE Spins Promotions

With the RNG, RTP, and volatility out of the way, you now have a complete perspective on the world of online slots. Oh, wait… there are still several more things you need to learn to fully maximize your chances to win whenever you play for real money on our one-of-a-kind online casino deposit bonuses.

Glossary of Common Online Slot Terminology

Slot machines have developed a lot since the first simple machines were introduced in the late 1800s. And the vocabulary associated with them has kept pace with these developments. Today the terminology can seem almost intimidating for new players. To help you feel comfortable in the world of online slots, we’ve put together a glossary of the terms you’ll come across in your gaming adventures.

Online Slots Type

Because each game provider wants to make their product different, there is an almost endless variety of slots out there. However, most of them fall into one or another of the categories listed below:

  • Three-Reel Slots: what most people consider ‘classic’. Three-reel slots are based on the original slot machines. Although relatively simple-looking, they can have up to five paylines and could offer big payouts.

  • Five-Reel Slots: Five-reel slots have, that’s right, five reels! This means they offer more paylines, giving you more chances of winning.

  • Multi-Spin Slots: Multi-spin slots, also called mega-spins, combine anything up to nine sets of reels, meaning you could be spinning 45 reels at a time. This gives you multiple chances of winning. The downside is you have to place a bet on each reel, making them quite expensive to play.

  • Progressive Slots: In progressive slots, a number of machines are linked together and share a jackpot, which increases with every play in the network until, as the song goes ‘The Winner Takes It All.

  • Bonus Slots: These slots feature bonus round usually if you land 3 or more scatter symbols. The feature can range from free spins & cash prizes to a wide range of special bonus options.

  • Video Slots: As well as five reels and numerous paylines, video slots are heavy on animation. Often, they are based on characters and themes from popular films or TV shows.


Like all forms of gambling, slots have their own vocabulary when it comes to placing bets.

  • Bet: Pretty self-explanatory, this is the amount of money you must wager to play. Most machines operate within a minimum-maximum bet range.

  • Cashback: Some slots and casinos offer a percentage of your cashback as an incentive to deposit a certain amount of money.

  • Coins: Not physical coins, these are the units you bet in. They change in size depending on the amount of your wager.

  • Free Spin: A type of bonus, free spins are triggered when you get certain symbols, combinations, etc, depending on the game.

Playing & Winning

Whether you play online slots for real money or just for fun, winning is important. Here are the terms associated with different ways of winning to help you maximize your chances.

  • Autoplay: This is a feature that allows you to set your own parameters for playing, such as number of spins and size of bets.

  • Bonus: A bonus is a feature on the game that gives the player extra chances of winning. These vary from game to game.

  • Jackpot: The jackpot is the highest amount you can win on a game. This will vary depending on the type of slots you are playing plus the size of your bet.

  • Payline: One of the most important terms in the world of online slots, this is the line that runs through the reels to connect the symbols. The right combination of symbols on a payline gives you a win. Online slots usually have between 1 and 243 paylines. Unless you are playing a Megaways machine, that is. Then the number jumps to a staggering 117,649!

  • Paytable: Since different slots have different winning combinations and payouts, these are all listed on the paytable on every machine so that you know exactly what you need to win.


We won’t go through all the symbols used in online slots as it would take us days. But as well as the standard symbols for the game, most also feature these extras.

  • Multipliers: These multiply your winnings by two or more.

  • Scatters: If you get a number of scatter symbols needed, you’ll usually receive bonus games or free spins.

  • Wilds: Like wild cards in poker, these symbols act as a substitute for any other (except scatters) to give you a winning payline.

Other Common Terms

The terms above form your basic slot vocabulary, below are the ones you need to take it to the next level.

  • Cold Slots: Usually refer to slots that haven’t paid out in a long time.

  • Hammer a Machine: Hammering a machine means playing the same machine for an extended period of time.

  • Hit and Run: The opposite of Hammering, this means quickly moving on from slot to slot.

  • Near Miss: This is the situation where you almost, but not quite, get a winning combination. Bummer.

  • One-Armed Bandits: A not-so-affectionate nickname for slots

  • Onesies: Players who don’t bet more than one coin per spin.

  • Signature Slots: Branded slots that can be found in online casinos.

  • Streaky Slots: Games that have both hot & cold streaks.

  • Sound of Rain: This is what it’s all about, the sound of rain is the noise the coins make as they come tumbling out of the machine when you hit the jackpot.

  • Stop Loss: Of course, you’re not going to hear the sound of rain every time you play so it’s always best to have a stop loss marker, a point where you stop playing for a while. This could be based on either time or money spent on play.
