September is the time of the year when developers begin releasing their best slot games of the year. The lead up to Halloween and Christmas is always an excellent time for slots players as the night draw darker and colder and we spend more time indoors playing our favourite online casino games.

ONLINE SLOT TRENDS IN SEPTEMBER 2025
After a Summer holiday, NoLimit City are back with two brand new slots: Dead Men Walking and Tanked 3: First Blood 2. You can expect loads of high-quality features in both of these slots as well as their usual extreme variance levels.
Interestingly enough, it seems like NoLimit City may now have a sister developer in the form of Sneaky Slots. The first release from Sneaky Slots will be Nip Tuck at the end of the month which comes in the same artistic style as NoLimit City slots plus extreme volatility.
Speaking of slots which will be released at the end of the month, we are highly excited for Gonzo’s Quest 2: Return to El-Dorado. The original Gonzo’s Quest slot and Gonzo’s Quest Megaways are two of the greatest slot machines of all time, so we expect great things from NetEnt here in what will be their biggest release for several years.
As always, we will be reviewing all of the slot games mentioned here via our slot game reviews section which will allow you to read more in-depth reviews of each of the games.
STEPHEN’S MONTHLY PICK: GONZO’S QUEST 2: RETURN TO EL-DORADO
NetEnt’s biggest slot release for several years, Gonzo’s Quest 2: Return to El-Dorado may well become the most played slot game ever upon release such is the hype for this one. Previous Gonzo’s Quest slots have been absolutely superb and we only hope that this one will be the same.
