Top 10 Best Online Slots

From jungle adventures to ancient gods, slot games come with hundreds of themes, and thousands of ways to win! Most top US online casinos have a variety of at least a few hundred games for you to try. These are some of the best online slots for 2023 and beyond.

Age of the Gods

Age of the Gods is a progressive jackpot slot that you can try at Caesars Palace and some other top US online casinos. The slots in this series are themed around ancient Greek gods, and they have four different jackpot levels, so you’ll have extra chances to take home a big win. The totally immersive games from Playtech also come with multipliers, wilds, and scatter symbols.

Cleopatra Fort Knox

The original Cleopatra game is super popular at US online casinos, and the Fort Knox version adds an extra element of thrill - this one includes a special bonus game where you’ll need to break into safes to try to win a progressive jackpot! With some many Egyptian themed games out there, this is one of the better options. FanDuel is a great place for you to try out this game.

Starburst

With its colorful gem symbols, win both ways feature, and the chance to win up to $50,000, it’s no wonder Starburst is one of the most popular slot games of all time. This NetEnt title shines in its simplicity - there are fewer features than most other modern slots, but you can look forward to flawless gameplay. Almost all of the top US online casinos carry Starburst, but we’d recommend you play at BetRivers.

Road to Riches

Join the glamorous characters on a journey across Route 66, as you go in search of some riches! The symbols take the form of bundles of dollar bills and sparkling diamonds, but you’ll really be looking to land the ladies, who will open up the bonus round for you. Overall, the gameplay is pretty simple, and the slot comes with a 5x4 grid and 50 paylines. You can play at some top US online casinos such as Tipico.

88 Fortunes

There are hundreds of Asian themed games out there, but 88 Fortunes does the theme really well - even the bet amounts are themed, ranging from $0.88 to $88 per spin. The game comes with a free spins round and multipliers so that you’ll have the best possible chance of landing yourself a big win. As Betway is one of the best US online casinos, we’d recommend this as a place to try 88 Fortunes.

Blazing Bison Gold Blitz

Fortune Factor’s Blazing Bison Gold Blitz comes with 4,096 paylines, an RTP of 96%, and the chance to win up to 5,000x your stake. You can play this slot now at BetMGM. There are lots of buffalo-themed games out there, but this one is particularly fiery, with three different jackpot amounts and the chance to buy your way into the bonus round. There are two special features - the free spins round that comes with multipliers of up to 5x, and the Gold Blitz round where you could win those jackpots.

Fortune Coin

Fortune Coin is one of the most popular wealth-themed slot games out there, and it’s available at Golden Nugget and many other US online casinos. The game comes with a huge 243 ways to win, and a high RTP of 96.2%. Some of the symbols to look out for include fiery dragons and other Asian wealth symbols like snakes and golden lions, and the game comes with four progressive jackpots, a free spins round, and wild symbols.

Emperor of Rome

This explosive game is a title in Playtech’s Mega Fire Blaze series, and you can play at bet365. Land three or more of the special scatter symbols to trigger the free spins feature that comes with Warrior Wilds, which can extend to cover the entire reel! You might even be lucky enough to land the Star Coin symbols, which can lead to one of the game’s four different fixed jackpots.

Gonzo’s Quest

Gonzo’s Quest is available at most US online casinos such as DraftKings. The game is set deep in the jungles of South America, and you’ll be going off on an adventure with the title character, complete with HD graphics and features like “avalance”, where winning symbols disappear and are replaced with more, for a chance at an extra win.

Types of Online Slot Machines

Online casino slot games come in all different shapes and forms, with their own unique themes and special features at the best US casino apps. Whether you’re into classic, fruit-machine style games, big progressive jackpots, or games with features like megaways and free spins, top US online casinos cater for everyone’s tastes. These are some of the best types of slot games for you to try.

Classic Slot Games

If you can picture an old-fashioned slot game that you’d expect to see in a Vegas casino, you can probably picture what a classic online slot looks like. These games tend to have fewer reels and paylines than other online slots, and the gameplay is a lot more stripped down, so you won’t find many special features or bonus rounds. The classic symbols to look out for usually take the form of fruit, bars, or 7s, and these games are ideal for newer online casino players.

Video Slots

Video slots are the opposite of classic slots - these come with all the bells and whistles, and usually feature immersive themes, HD graphics, and lots of special features. Video slots are made by dozens of different online casino and US live casino providers, so there’s a massive variety of thousands of games to choose from.

Progressive Jackpot Slots

Many online slots have jackpots attached, but progressive jackpots are extra special because the amount you can stand to win increases every time someone spins anywhere on the slot game network! This means that the top prize pots can reach up to seven or eight figures. 

Progressive jackpot games often come with special features like bonus rounds, free spins, and lots of ways to win, so even if you don’t win the biggest prize, they’re still worth playing.

Megaways Slots

When you play most slot games, the number of symbols that land on the reels is the same with every spin. Megaways games really mix this up - the number of symbols keeps changing, so you’ll have thousands of ways to win! There are hundreds of megaways games out there, and this really exciting gameplay mechanism makes them much more fun than standard slot games. Megaways games can come with special features just like all other slots.

Interactive Online Slots

While all slots run on Random Number Generator technology, there are some that can be a little more interactive than others. While you’ll never have an influence on what symbols land on the reels, there are some games where you can choose your bonus round or use a gamble feature to try to double or even quadruple your winnings. To trigger one of these more interactive features, you’ll usually need to land a certain number of a special symbol.

Slots With Bonus Games

Many modern online slots come with free spins bonus rounds. Progressive jackpots, megaways games, and other types of slots can all come with bonus rounds, and they’re usually trigged when you land enough of the special scatter symbols on the reels. Depending on the slot, you could bag as many as 30 free spins! Free spins rounds often come with multipliers, expanding reels, or wilds, which can increase your winnings.

Online Slots Offers

When you’re signing up at an online casino, you’re going to want to choose one that has a great welcome offer, and lots of promos for regular players. The best US online casinos offer a whole host of different offers for both new and existing players. Some of the most popular offers include free slots offers and matched bonuses, but depending on the casino, you might find something unique.

You can always come back to Bookies.com to check out what’s new in the world of online casino offers, and when you sign up through a link on this page, we’ll ensure that you get the very best ones out there.

Free Spins

While some online casinos use the term “free spins” to refer to extra spins that you get when you make a deposit, it’s more commonly used in the context of spins that are totally free and awarded when you sign up and log in. You’ll be able to use your free spins on selected games, and there’s really no risk because you don’t need to deposit any of your own real money in order to claim them.

Online Slots Bonus Games

Bonus games are free spins on slots, that you can claim when you make a qualifying deposit at an online casino. Some casinos have bonus games as part of the welcome package, while others award regular players with bonus spins all the time. You’ll usually need to use your spins on selected games only, but the good news is that these are often some of the world’s top games, like Starburst or Book of Dead.

Online Slots Deposit Bonus

A deposit bonus is probably the most common form of online casino bonus. You’ll usually get a percentage match on your first deposit, for example a 100% bonus up to $100. You can go off and use your bonus on almost all of the slot games at online casino apps, although sometimes there are a few exceptions. 

This is a great way to explore the online casino website and even stand a chance at a real money win on top slot games. Keep in mind that wagering requirements might apply, so you may need to play through your bonus amount a certain number of times before you can withdraw.

Online Slots No Deposit Bonus

Some top US online casinos have no deposit bonuses for new players, so you’ll get something for free before you even make your first deposit. No deposit bonuses can take the form of some casino credits that you can use anywhere on the online casino website, or free spins on selected games.

Loyalty Programmes

All of the best US online casinos have a loyalty program to reward regular players with something special. Some loyalty programs allow you to build up points when you deposit and wager, and then redeem these for bonuses and other prizes, while other loyalty programs work on a calendar system that gives you promotions on certain days of the week, or times of the month. 

Some online casinos also have VIP programs, where the very top tier players can look forward to enhanced bonuses, exclusive gifts, and priority customer support.

How to find New Online Slots

Big game providers such as NetEnt, Pragmatic Play, and Games Global launch new slot games all the time - as often as a few every month! In general, online casinos are pretty quick to add these new games to their selection. If you’re already signed up at an online casino, the best thing to do is to visit the “new games” section, which is located in the games lobby at most online casinos. 

Another great way to find the best new online slot games is by visiting this page here at Bookies.com. We’ll be sure to update it whenever great new slots are released, so you can head off to your favourite online casino and play.

How to Play Slots Online

There are so many different slot games out there, so it makes sense that each one is a little different. For example, some games require you to match the same symbols on adjacent reels from left to right on a specific payline, while others have a “cluster pays” feature where symbols just need to touch. 

Some games come with megaways, where the number of symbols on a reel changes all the time, and others still come with big progressive jackpots that can be triggered either when you land special symbols, or on any random spin.

To get started with playing slots online, you first need to sign up at an online casino through a link here at Bookies.com. Make your first deposit and claim any available welcome offers, then head to the games lobby to start playing your favorite game.

Before you start spinning, it’s always a good idea to check out the pay table and game info so that you know what you’re looking for. Check if the game comes with any progressive jackpots or special features like bonus rounds, which most modern slots have.

Next, use the options on the screen to set your stake at a level you’re comfortable with, and adjust the paylines if that option is available. The only thing that’s left to do is click on the spin button and watch the symbols land on the reels.

All slot games at reputable online casinos use Random Number Generator technology, which means there’s nothing you can do as a player to change the outcome. If you’re lucky enough to land a win, the funds will be added to your online casino balance automatically.

Online Slots Bonus Terms and Conditions

When you’re signing up for your new online casino account, no doubt you’ll be keen to get started and claim your special welcome offer. It’s important that before you make a deposit, you ensure that you’re familiar with the key terms and conditions that come with the promotion. 

Almost all online casinos have terms like wagering requirements, time limits, and game restrictions, but there might be more unique terms applied to certain promos, so it’s always best to read the full T&Cs which you can find on the promo page or in the footer of the online casino website. These are some of the most important T&Cs to be aware of.

Wagering Requirements

Wagering requirements define how many times you need to play through the bonus amount, deposit plus bonus amount, or free spins winnings, before you’ll be eligible to withdraw. Wagering requirements can be quite high at some casino apps, for example 35x or even 50x, but you might get lucky enough to only need to wager 1x or 5x. 

You should also check if any games are excluded from wagering requirements, as high RTP slots, jackpots, and table games often don’t contribute, or contribute a smaller percentage than other games.

Time Limits

Time limits determine how long you’ll have to use your bonus, or to meet the wagering requirements. Most online casinos give you about a week to do this, but in the case of free spins, you might only be given 24 hours to use them.

Some online casinos also apply a time limit to meeting the wagering requirements, so you’ll want to ensure that you’ll fully prepared for this, as you could forfeit your winnings if you don’t wager enough in time.

Win Limits

Win limits refer to how much you’re allowed to win from a specific online casino promotion. Almost all no deposit offers have a win limit, but you might find that some matched deposit offers do too. While win limits can be generous at some online casinos, others restrict you to winning only $1 per free spin. 

If you do happen to have a win that goes over the limit amount, you’ll unfortunately have to forfeit the extra.

Game Restrictions

Game restrictions are applied to almost all free spins offers, and some matched deposit bonuses. Free spins offers are usually only valid on specific slot games, and you won’t be able to substitute them for any others. 

When you claim a deposit match, you have a wide variety of games to choose from, but an online casino might exclude certain games - while casino bonuses are generally valid on most slots, many online casinos don’t allow you to use bonuses on live dealer games or other table games.

Withdrawal Limits

In addition to win limits applied to specific promos, most online casinos also have an overall withdrawal limit, which is based on the casino as a whole. For example, you might only be able to withdraw $1,000 in a single transaction or you might be limited to $5,000 per week. 

You’ll sometimes be able to get in touch with the support team to request a higher withdrawal amount, and if you’re a VIP player, you can usually also withdraw more.

Are Online Slot Machine Games Legal in the USA?

It’s tricky to answer this question in simple terms because online slot machines are legal in some states but not in others. US states have the ability to regulate online gambling themselves, and while some states choose to allow online casinos, they’re in the minority: at the present time online slots are only available in Connecticut, Delaware, Michigan, New Jersey, Pennsylvania and West Virginia.

If you’re located in one of these states and you want to play online slot games, you’ll need to make sure that you’re signing up at a licensed and regulated online casino. Each state has its own governing body to license casinos, so you’ll need to look for their stamp of approval before you play. All of the casinos that we recommend here at Bookies.com are licensed and regulated.

When an online casino has a license, it means that it has been approved for game fairness, high levels of data security, safe payment methods, and other factors. Licensed online casinos in the six states we mentioned are all able to offer online slot machines, as well as other forms of online casino gambling, like table games and live dealer games.

Because the regulations around online gambling are changing all the time, there’s a chance that online casinos might become available in other states in the future, and when that happens we’ll be sure to update this page.
