New Online Slots at Social Casino
The players located in states with real money online casino gaming don’t get to have all the fun.

These new online slots can be played using gold coins (which have no value and are played only for social purposes) or sweeps coins, which can be won or you can grab free SC coins as a welcome bonus and redeemed for prizes. There are fewer new online slots at social casinos than at real money online casinos, but a handful of offerings have launched in the past month that players will want to test out. Social casinos, which are sometimes referred to as sweepstakes casinos, are becoming increasingly popular because of their availability in most states.

Upcoming Best Online Slots
There are so many new online slots coming out on a regular basis from top software providers like Evolution Gaming and Red Tiger Gaming as well more indie software developers that it’s impossible to list all of them. That being said, a handful of upcoming launches from some of the industry’s top developers have us really excited that we think you will enjoy playing, with factors like innovative features, high RTP and unique themes driving anticipation for these upcoming releases.
As is the case always, it’s important for individual players to test out demo versions of these games to explore different types of new online slots and find the ones that best match your preferences. Some bettors may be looking for high RTP, while others simply want the wildest, animation-heavy experience possible. Find what’s right for you and then start spinning those reels.
A few examples include some food-themed new online slots, including a 5x3 reel with 243 ways to win with Cereal Killers and American Burger Bounty. It’s always big news when Pragmatic Play launches a new offering, and players will gain access to Bigger Barn House Bonanza, an extension of the wildly popular Barn House Bonanza. We expect the animations to be super fun with Halls of Odin, a new online slot with vikings and mythical beasts included. All41 doesn’t have many releases, but it packs a punch when delivering a new online slot. That has us excited about the upcoming Thunder Riches Buffalo.
| Game | Provider | launch date |
|---|---|---|
| American Burger Bounty | Red Tiger | September 15th |
| Halls of Odin | Backseat Gaming | September 16th |
| Cereal Killers | Light and Wonder | September 18th |
| Bigger Barn House Bonanza | Pragmatic Play | September 22 |
| Thunder Riches Buffalo | All For One Studios | September 24th |
I’m a fan of outside-the-box online slots when it comes to themes and animations. So, pardon the pun, but Cereal Killers looks like it’s going to be a blast. A solid RTP of 96.1% and 243 different ways to win is also great, but the creepy cereal theme is going to be fun.

How to Find the Newest US Slots at Online Casinos
It can be difficult to keep up with news and announcements of the newest US slots online. Because they are released seemingly every week, it’s almost impossible to always know what’s out there. But that’s why we’re here.
For starters, Bookies.com will always have a current, up-to-date list of the newest online slots. While the list won’t be exhaustive (how could it be?!), it’ll have our favorite picks and the most popular options from the leading software providers. Make sure to bookmark this page so you can come back and see what’s new and being offered by the leading software developers and the best casinos.
Speaking of software providers, players can always check in on those websites like Pragmatic Play, NetEnt and Playtech to see what they’re offering up and when the games can expect to drop. They’ll obviously have the most current information and may have exclusive details that the public and others aren’t privy to. They may also have the earliest demo versions of the game, so you can try them out as soon as possible.
Of course, the best way to know what is dropping and when is to log into a new online casino of your choice and check for yourself. Once you register, you can immediately play online slots without the need to download any software. Many top online casinos have a specific page for new games (not just limited to new online slots), which means rather than just knowing about upcoming releases, you’ll get to actually play those games for real or in demo mode.
It’s also good to follow trusted casinos on their social media accounts and to subscribe to newsletters since they’ll be pushing ongoing promotions to attract players for these new games, too. Don’t forget to take advantage of welcome bonuses offered to new players and loyalty rewards for existing players when they sign up for the latest slots.
Pros And Cons Of Trying New Online Slots
New online slots offer a change of pace for players who either have their favorite or popular slots that they always go to or are bigger fans of live casino table games such as online roulette or card games like online blackjack and online baccarat. That’s one of the biggest benefits of trying new real money online slots. Playing the same games all the time can get boring after a while, and the themes, animations and sounds that new online slots pack offers something entirely different than most players are used to.
As technology grows and competition in the space ramps up, these new online slots are always getting better in terms of gameplay, mobile adaptability and overall user experience, which can significantly improve your enjoyment and chances of winning. That’s not a knock on the older games, but some of them can feel outdated for various reasons. New online slots are not going to look and feel that way, giving players plenty of reason to try them out.
Online casinos often offer specific bonuses or free spins on new slots as a way to entice players to try them out. If bettors are able to use house money to make their spins or potentially increase their winnings at no additional cost to them, it’s a no-brainer to try out.
The cons are minimal, but if we had to choose one, it would be that sometimes newer operations can have kinks that need to be worked out. Some of the older online slots have been live for more than a decade and function without any hiccups. That may not be the case with some new online slots, though it’s not a problem we’ve ever run into. Playing the demo version of the new online slot you’re interested in is also a good way to get a feel for it without actually using your funds on a game you might not like, while helping you manage your budget and avoid unnecessary losses.
What To Look Out For In The Best Slots?
There’s plenty to keep in mind for players who are deciding on whether or not to try out a new online slot. First and most important, you’ll need to know if you’re located in a state that offers legal online casino gaming, such as West Virginia Online Casinos or New Jersey Online Casinos, where licensed and regulated platforms ensure fair play and security. You’ll also want to make sure the online casino you’re signing up with has that game and holds a valid license from reputable authorities.
All online casinos are constantly offering new online slots, including real money slots and free online slots for new players to try, so that shouldn’t be an issue as long as you’re in a state where you’re legally allowed to play. Players who aren’t in a state with legal online casino gaming can always try out demo versions of new online slot games.
Just as important is the RTP, which stands for Return To Player and reflects how much a game pays back to players over time. This is the percentage of all wagered money that a new online slot pays back players over time. For example, a new online slot with an RTP of 97% will pay back, on average, $0.97 for every $1 wagered. That doesn’t guarantee anything - these simulations are run tens of thousands of times - but it does give you a good feel for volatility. The higher the number, the better chance of a payout, so it’s wise to avoid slots with low RTP percentages.
You should also look out for features like progressive jackpots. In progressive jackpot slots, players increase the prize that could be won each time the game is played, but the jackpot is not won. This gives players the chance to win massive jackpots without placing a huge initial bet.
You’ll want to do your own homework on all new online slots, and you can always try them out as demo versions. But it’s also good to read reviews from experts like the one on Bookies.com to learn about the game mechanics, reliability and security features, including the use of random number generators to ensure fair and unpredictable outcomes. This can set expectations for once you actually go in and play the game yourself and help you make choices that suit your preferences and budget.
You’ll also learn more about the new online slot upfront instead of going in blindly and making your spins. This will help you understand the rules of the game, the different ways to win, and any other bonuses or jackpots that could be in play for you, including wagering requirements for bonus offers and the convenience of using different payment methods for deposits and withdrawals.
Gamble Responsibly
New online slot games are exciting for a host of reasons. It’s a sparkling, new product that’s never been played before, it gives players a unique experience and there are often generous bonuses attached as incentive to try the games, but it’s important to remember outcomes are always unpredictable.
But it’s important to remember that players betting on new online slots needs to be done responsibly and within your means. There isn’t a faster-paced game type in the world of online casino gaming than slots, which can take just mere seconds to complete. That means it can also get out of hand, so players will want to make sure they’re not betting more than they can afford to lose and avoid chasing losses by making responsible choices and sticking to your budget.
One great alternative for starters is to try the demo version of the game. Instead of using your own funds to try out the game and get a feel for whether or not you like it. You can’t win real money, of course, but it’s a safer way to ease into the game.
At online casinos, players can always set deposit and betting limits for themselves, freeze their accounts or put time limits on the amount spent at the online casino itself.
