RegionsSeptember online slot releases
Published: September 1, 2025
September is here, bringing with it an entirely new host of online slots for Canadians to enjoy. As the weather gets colder, we have the perfect excuse to sit at home and play games.
Just in time, too. A large number of well-known software providers are launching at least one title in September. With so many options to choose from, picking the best online slot was not easy.
Once again, Microgaming succeeds in winning us over with the help of their partner studios. Two of their releases made it into our September top five. Canadians can also look forward to titles made by Pragmatic Play, Yggdrasil and Quickspin. How will the best September slots stack up against their competitors?
Sabres and Swords Charge
Toy soldiers remain remarkably popular even to this day. This is something Yggdrasil and Dream Tech are no doubt well aware of. That is why their latest title, Sabres and Swords Charge, uses them as the backdrop for their action.
The slot takes place during a fierce battle between soldiers. On the reels, their toy nature is quite apparent. In the background, the artists lean more into how these battles would look in someone’s imagination.
Gigablox makes a return once more, but they are accompanied with a free spins round. You can score free spins by playing the game or by buying them directly.
With the assistance of these special features, Sabers and Swords Charge features a maximum win worth 2,880x your total stake. The title also has an above-average RTP, which sits at 96.11%.

After the astounding success of Big Bass Bonanza, a sequel was inevitable. For most developers, that would mean slapping two at the end of its name and adding a new feature.
Instead, Pragmatic Play opted to make this game bigger. Larger reels, more paylines, even better jackpots. The title truly lives up to the name Bigger Bass Bonanza.
This time around, the game takes place off the coast of Miami. We can see the bright colours of the beach above the reels. It serves as nice eye candy, but our focus will still be beneath the waves where the big wins are.
The highest RTP possible for this release is 96.71%, which is the same as Big Bass Bonanza. However, Bigger Bass Bonanza features both a larger top prize and higher volatility. The largest jackpot you can win in this slot is 4,000x your total stake.
Mega Moolah The Witch’s Moon
Lovers of progressive jackpots have no doubt heard of the Mega Moolah series. Just in case you have not, this Microgaming progressive jackpot frequently pays multi-million prizes.
This time around, Microgaming is cooperating with Aurum Studios to make another entry in the Mega Moolah series. The result? Mega Moolah The Witch’s Moon.
We like the visuals present in this game. Microgaming and Aurum Studios opted for a magical theme. The team does a fantastic job of bringing the witch’s lair to life. They also made it more whimsical than creepy, which we quite like.
As with all Mega Moolah titles, the biggest possible win in this slot is unlimited. Not counting the progressive jackpot, Mega Moolah The Witch’s Moon comes with low variance and a 1,920x top prize. It also has an RTP of 88.12%, so be careful while chasing that big win.
4 Diamond Blues Megaways
Over the years, slots that carry that old-fashioned feel have become quite popular. We can certainly understand it, even if it is not our cup of tea.
Such classic slots tend to offer very few if any special features. Fortunately for us, 4 Diamond Blues Megaways by Buck Stakes Entertainment and Microgaming does things differently.
If you want a title that looks like the one-eyed bandits from the past, you are at the right place. However, no physical machine could have the number of reels and paylines change as this video slot can. It offers the best of both worlds: fantastic visuals and interesting special features.
Thanks to rolling reels, Megaways, free spins, and multipliers, you can win up to 29,000x your total stake. An impressive jackpot and one that perfectly suits this game’s high volatility. The title’s RTP varies depending on the market, with the highest value being 96.4%.
Big Bad Wolf Megaways
September also brings us a follow-up to one of Quickspin’s most iconic slots: Big Bad Wolf. The team decided to return to it once again, this time adding in the Megaways system.
Fans of the original will immediately spot how familiar Big Bad Wolf Megaways looks. This new release also features a higher variance and a much bigger top prize.
We quite like the small visual changes done to the new version. Given that the original Big Bad Wolf launched back in 2012, the update was inevitable. It keeps the spirit of the original game while still showing how talented Quickspin’s artists have become.
Fans of high volatility games will love Big Bag Wolf Megaways. Alongside its high variance, it also has a mouth-watering jackpot worth 30,540.35x your total stake. This title also comes with three RTPs depending on the market: 90%, 94% and 96%.
Final words
We did not expect September to be so heavy on sequels to popular slots. While not all of them made it on the list, we were surprised how many did. Not that we are complaining, mind you.
A new Mega Moolah entry is excellent news for casino members who want to play progressive jackpots and scoop some handsome prizes.
Big Bad Wolf Megaways brings an almost decade-old classic and freshens it up. Bigger Bass Bonanza improves on the already popular original, making it even better.
Of course, original titles are not that far behind either. 4 Diamond Blues Megaways allows us to enjoy classic themed slots with plenty of fun bonuses attached.
Similarly, Yggdrasil’s Sabres and Swords Charge gives us a fun theme and an option to play with the Gigablox feature. Overall, September looks like it will be another exciting month for slots.
We cannot wait to get our hands on these games! So, we’re looking forward to the September slot bonanza. Hope you are too.
