With the summer gone, many online casino fans have started to flock to online slots yet again. After all, there’s not as much to do outside anyway. Both Realtime Gaming (RTG) and Betsoft have released new slots for September 2021. Also, there are many leftovers from the summer months that you might’ve missed. In this article, then, we’ll take a look at four of the best September 2021 online casino slots for USA players!


Tower of Fortuna

Tower of Fortuna is Betsoft’s best new online slots for real money September 2021 slot. It’s a polished real money slot with a compact playing field. It has 3 reels, 3 rows, and a total of 5 paylines. That’s not a lot, you’d say, but wins come often in this one. The variance is medium, which makes the slot a good fit for low rollers and big spenders alike.

The jackpot is 3,200x your bet and you can play for many different stakes as well. The min bet is $0.60, while the max bet is $9.60 per round. That makes for a max win of $30,720. That’s if you play for the max bet and hit the jackpot. The theoretical RTP of the slot is slightly above average, 96.06%.

For bonus rounds, there are Climbing The Tower Multipliers, Crimson Flag Wilds, and Fortuna’s Free Spins. Suffice to say that the slot packs a punch with those. The main idea is that you can climb the tower with no-win spins. By doing that, you’ll increase your win multiplier.

More importantly, the win multipliers apply to your next win. In other words, even no-win spins do something for your wins going forward. It’s a novel concept to be sure and we hope it will appear more often going forward. It’s always nice to see online slots rewarding players for their loyalty. Tower of Fortuna does just that!

7 fortune frenzy slot

7 Fortune Frenzy

7 Fortune Frenzy is a classic Betsoft slot that caters to players that fancy old-school games. It has a simple playing field with 4 reels and a single payline. Only the first 3 reels show symbols and blanks. The fourth reel is there for the bonus rounds. The theoretical RTP of the slot is bang on average, 96%.

You can win up to 2,368x your stake. The betting range runs from $0.06 to $30 per game round. That’s across the top legal online USA casinos, so you can make your pick. The gameplay revolves around getting wins on a single line. You need any combo of 3 symbols, which sounds simple. It’s the blank positions that complicate matters.

If you line up the payline combo with a modifier on the 4th reel the payout will be grand. There are multipliers, win multipliers, and respins. You can chain respins together to get a better payout potential. That’s the key to big wins!


Legend of Helios

Legend of Helios is the number one RTG video best slot for September 2021. It has a theme taken from ancient Greece and it has some flashy bits on offer. The setup is fresh, for one. There are 5 reels, arranged in a 4-3-4-3-4 fashion. That produces 25 paylines, with bets ranging from $0.25 to $6.25. The variance is medium-high and the jackpot is 2,250x your bet. No official word on the RTP, but we estimate it’s in the vicinity of 96%.

The bonus rounds include Mystery Stacks with Respins and a Bonus Wheel. Mystery Stacks are Mystery symbols that can trigger respins when found fully on the first two reels. These respins continue until you get a win. Land 3 Bonus symbols and you’ll get a spin on a bonus wheel. This can lead to one of 3 free spins options. Or a coin win, depending on your luck.


Sparky 7

We conclude the best slots online for September 2021 list with Sparky 7 from RTG. This brand new RTG slot offers a classic theme full of sevens. It has 3 reels, 3 rows, and 5 paylines. In other words, it continues the trend of simple playing boards on this list.

You can play for stakes between $0.50 and $5 at our top USA casinos slots online. That makes the top win $250,000, as the jackpot is 50,000x. The theoretical RTP is somewhere around the 96% industry average.

You can look forward to quite a few bonus rounds as well. The top base win is 500x for a full line of Red Sevens. You can then get Transferring Symbols when you get two Sevens and a blank slot. This can net you a Seven or a Wild to complete your combo. Or it can net you nothing useful.

There’s also the Free Spins Feature that you’ll trigger via 3 Bonus Scatters. The formula is simple. You’ll get 7 free spins and a chance to win Multiplier Wilds or Win Multipliers. That’s where the fun is and where the big payout potential lies. Sparky 7 is a highly volatile best slot machine online. Therefore, you’ll have to grind a bit for the best results. We recommend you manage your bankroll properly.


Final Word

September 2021 was a great month for online slot gaming for US online casino slots players. Some slots left over from the summer months, as you’d expect. 7 Fortune Frenzy and Sparky 7, we’re looking at you! Then, there are new Betsoft and RTG releases in the form of Tower of Fortuna and Legend of Helios.

Nothing extreme, here, it’s more about sitting back and relaxing. The jackpots are low, but so are the volatility levels. Suffice to say that Tower of Fortuna is an excellent choice for clearing casino bonus wagering requirements. It will get you through those in no time at all!

Note that all the mentioned slots are available across our best USA online casinos. You can even play them all as mobile slots or free slots. That means on the go or without any risk. We recommend you play for play money at first. That way, you’ll know exactly what you’re getting into. Without any stress either, which is great.
