Moreover, new online slots for September 2023 may not have yet been added to the slots category at your favorite online casino or any slot sites in the US, but they will most likely be found there soon.

The best online slots might not be available in your state either, but we hope that all of these games will be available to you at some point in September 2023.

Jungle Bonanza

Jungle Bonanza is exclusively available at FanDuel Casino, but if you have never before registered with the gaming site in MI, PA, or WV then you can wager up to $1,000 on Jungle Bonanza or any slots with the knowhow that any net losses will be returned in bonus funds within 72 hours.

With an unusual 6x4 layout, the Jungle Bonanza slot is a welcomed new addition to FanDuel Casino for September 2023, with the title providing respins, free spins, wilds, bonus rounds, and more.

Brought to you by Blueprint Gaming, who are known for the likes of Eye of Horus and Fishin' Frenzy, but also TV-themed slots like The Goonies, Ted, and some others. But, Jungle Bonanza is a slot title that can be considered one of their best, and as long as you are signed up with FanDuel Casino then you can try it for yourself today.

Dinero Loco

Dinero Loco is not only a new slot to online casinos in the US, but it was only recently released by Incredible Technologies. Yet, it's still one of the best online slots real money you will find at online casinos or on casino apps.

The slot game will be found at BetMGM Casino, and Borgata Casino from the recommended online casinos in this article, meaning you are limited to just a couple of places you can play it at.

But at either, if you are able to register, you will be able to play it with a no deposit bonus, followed by a deposit match bonus too, allowing you to play one of the best online slots for real money without even having to add any at first.

Bonus scatters will trigger the Dinero Loco Wheel Bonus, which will then decide which bonus will be played, the Money Catch Bonus or the Progressive Piñata Bonus, either of which will see you rewarded with a healthy payout on Dinero Loco.

Bust The Mansion

A high volatility slot with a 94.09% RTP, meaning it will be perfect for those of you who like to play online slots to win big rather than see frequent payouts of small amount on low volatility slot machines.

The way that you will win big on Bust The Mansion (image below) will be through the Mini, Minor, Major, and Mega jackpot symbols that are worth 20x, 50x, 200x, and 1,000x your stake, while the ultimate goal is to land the Grand Jackpot worth 5,000x your stake.

Bust The Mansion Slot

This is a Link & Win game, which is a bonus that will be triggered by 6+ vault money symbols anywhere on the slot, with the burglary alarm going off to signify that you have triggered it. To win the Grand Jackpot in the bonus round, you will need to fill all the reel positions with the Money Vault symbols, and you could have 10, 15, or 25 free spins to do so.

Try and land a big win today playing Bust The Mansion at numerous real money online casinos in September 2023!

Transylvania: Night of Blood

Offering you an alternative from Blood Suckers or Immortal Romance in September 2023, two very popular horror-themed slots at online casinos, is Transylvania: Night of Blood.

Brought to you by the high-quality developer Red Tiger Gaming, the fast pace of Transylvania: Night of Blood is part of the reason we love it, but we can't ignore its three thrilling free spins rounds.

We felt that Red Tiger Gaming would tell it best, and this is what they say about Transylvania: Night of Blood and its bonus rounds on their website:

Scatter symbols of majestic but sinister creatures crawl onto the reels before an atmospheric backdrop. Vampire Bites may randomly infect symbols, turning them into Wilds to substitute for Win Way matches. Werewolf scratches may sever symbols to turn them into Ways Multipliers, enhancing your potential wins. Behold Free Spins! They may manifest in 3 thrilling versions. Vampire Scatters take you to Vampire Spins, where Vampire Bites may swarm the reels. Werewolf Scatters drag you to Werewolf Spins, where Werewolf Scratches may tear into the reels. Alas, should a Vampire and a Werewolf be summoned to the reels simultaneously, you end up in Battle Spins, with vicious Vampire Bites and savage Werewolf Scratches raining down on the reels. Follow the creatures of the night—if you dare—but beware! Your blood may turn cold when you come facing the giant beasts.

Max Megaways

A more familiar slot developer for Max Megaways is Big Time Gaming, the creator of the engine and Megaways slots, with this title being no different in offering the amazing 117,649 ways to win.

On top of that, Max Megaways (image below) has a strong 96.37% RTP, and can see you land a top win of a phenomenal 139,200x your bet if you are extremely fortunate.

Max Megaways Slot

If you are a fan of the Bonanza slot machine, this offers you something new and different in September 2023, but still resembles some similarities to arguably Big Time Gaming's most popular slot.

Sat on a sunny, beach-like background, Max Megaways has scatters, 3 of which will see you enter a free spins bonus, while you can also benefit from the Double Multiplier, Duplicating Wilds, and 2 Scatter Retrigger too.

Ice Heist

This slot is perfect for those of you who, even despite growing up, still like themselves a cartoon. By playing Ice Heist you aren't quite watching a kids cartoon show but instead playing for real money, keeping alive the child in you but while still doing adult things!

In the base game, the female thief is the highest paying symbol, and if you are able to see five of the female thief in combination you will end up being rewarded with up to 1000x your stake.

But as usual, the features to look out for on Ice Heist are the free spins feature and Diamond Accumulator, both of which will lead to thrilling gameplay and payouts.

Check the Ice Heist slot out at BetMGM Casino, Borgata Casino, and FanDuel Casino this September 2023 and play one of the best online slots for real money!

Diamond Rush

The Diamond Rush slot by AGS is a new title that has been added to BetMGM Casino and Borgata Casino for September 2023, meaning it can be played with a no deposit bonus for real money if you are just signing up with either of those gaming sites.

And we can see why, even though both already had enough high-quality games, why they have added Diamond Rush to their games collection.

It is another high-volatility slot to add to this list of best online slots, meaning you will have to be patient to trigger one of the 324 paylines.

What will help trigger those though are three plunger scatter symbols, because if they are to appear on reels 1, 3 and 5, they will see you land eight bonus games. The Diamond Rush slot also has the Power XStream bonus where wins are multiplied by the number of symbols per reel when you land a winning combination.

Over The Moon

Another megaways slot that has only recently been added to certain real money online casinos in the US is Over The Moon from Big Time Gaming.

With a generous 96.55% RTP, Over The Moon (image below) is a slot that you will want to try, even if only in demo mode, when you first sign up with the online casinos that offer it.

Over The Moon Slot

Its gems and card symbols give it a classic feel like any slot machine you would find at land-based casinos, but its background certainly helps give off that intergalactic theme, even if only subtly.

Colt Lightning

Colt Lightning was released earlier this year but has only recently been introduced to online casinos in the US in September 2023. It's music to the ears of us, who believe it is comfortably one of the best online slots produced by Play'n GO, and one of the top slots you will find at US real money gaming sites.

The RTP of Colt Lightning varies on different platforms, with it being as high as 96.24% in places. Make sure you check before you start playing if you are interested in making small gains, something that you shouldn't see a lot of when playing Colt Lightning due to its high volatility.

However, for those of you who like to stake big and patiently wait for that big payout, the Colt Lightning could be a new favorite of yours. There is plenty to talk about when it comes to Colt Lightning, especially in regards to the fact that the grid will shift and potentially expand while you play.

But nothing is more important than the bonus features that you will undoubtedly want to trigger on the Colt Lightning slot, and these are the Colt Strike, Rapid Re-spins, and Super Colt Spins.

Beavis and Butt-Head

Fan of the TV show but have never given the slot a try? Check out the Beavis and Butt-Head slot which is a new arrival at select online casinos in the US for September 2023.

Beavis and Butt-Head (image below) was originally released in 2019, but it has not long been available at US online casinos. So, if you like the TV show as we have mentioned, then you will want to give the Beavis and Butt-Head slot with plenty of bonus features a try.

Beavis and Butthead Slot

You have three different free spins features you can trigger in Beavis and Butt-Head, hopefully one of which you come across when playing the game, and they are:

  • To ‘B’ Or Not to ‘B’ Free Spins
  • Maxi Mart Free Spins
  • The Great Cornholio Free Spins

On top of that, there are numerous other bonus features to look out for on this 95.49% RTP slot from Blueprint Gaming, which has a max payout of 10,000 times your stake.

Play Beavis and Butt-Head at real money online casinos in the US today, because it is without doubt one of the best online slots for September 2023.

What To Look For In A US Slots Site

There are more than just these factors to look out for when registering with a US slots site, but these are inarguably some of the most important. You want to feel safe and rewarded when signing up with a US slots site, and we believe that the ones we recommend encompass everything you could possibly ask for.


Licensing is always top of the list in regards to what to look out for in a US slots site, because as long as they are licensed then your information will be safe and secure. On top of that, you will never have to worry about problems with a US slots site that is licensed withholding any money from you or providing you with certain issues as some offshore operators do.


It's incredibly important that a gaming site that we are recommending to play online slots has a solid reputation, which can be seen in online reviews, through awards they have won, and maybe even just through word of mouth. In addition to that, a big player base is always helpful because it indicates many people like playing at that online casino, as well as them treating their customers well.


Arguably the most important factor of all, bonuses are crucial when judging a US slots site. And this is not just welcome offers, it's just as important that they have promotions for existing players too, like a VIP program or regular day-to-day ways to receive free spins or bonus funds.


If a US slots site had just a small selection of online slots available it wouldn't be very beneficial for people who like playing those games. Though players might have their favorites, being able to test out different ones should always be an option and encourages people to play more than just their usual, especially when you have bonuses available to use.

Customer Support

If you do encounter any issues like a problem with making a withdrawal or you are unable to find the information you need through FAQs or T&Cs, you will want to make the process of speaking with the US slots site as seamless as possible. Whether this is through a live chat, email, or over the phone, you will be looking for strong customer support to resolve any problems you are having swiftly.
