Top 10 Most Popular Slots of October 2021

Home » Top 10 Most Popular Slots of October 2021

The assortment of modern online casinos consists of slots and table games. Someone chooses a more lively experience playing live table games, but the slot machines still hold the lead. This type of gambling entertainment is the most popular among gamblers. It is the perfect combination of thrill and an exciting pastime. That’s why this article comes in handy if you play slots and follow the latest gambling updates.

Today there are thousands of different slot games — from old-school «books» and «fruits», three-reels-three-rows Sevens to modern scratch card 4-reels games. And every year, these or those slots hit the top charts changing the industry standards and ruining the stereotypes. Which ones will be popular in October 2021?

Of course, it is really difficult to indicate any specific games in this case, since each player has his own preferences and tastes. Our list of the best online slots may differ from others, but we attempt to remain impartial and objective. Today we will try to determine by what principle certain games appear on the main page of an online casino. Let’s discover what features can rocket slot game‘s popularity.

Design & Functionality

First of all, this is the theme and visual design. Each new season brings new trends with it — this seemingly simple rule explains why the Egyptian theme was at the top one year, but this fruity classic returns the next year.

The thematic trend is dictated mainly by gaming studios, which carefully study the preferences of the players and offer them those slots that will be in demand. Often, such studios are inspired by current global trends.

For example, in the last few years, retro and nostalgia for the 80s have returned to fashion. This was reflected in clothing, movies, and neon-vibrant 80s style, and all-time classics slot games.

RTP & Winning Chances

The second principle is the RTP (return-to-player) percent. Gamblers prefer slot machines where it is at least 90%, while those where it is about 95% go to the top.

It is not difficult to understand the meaning of this term: it stands for the amount of money that will be returned to the player in the long run. So, if the return percentage is 90%, this means that out of the $100 spent, the player will get back $90. Naturally, the players expect to win more money than they spent, and get a net profit. The chances to save your money and get extra funds increase in games where the RTP rate is higher.

Slots with an RTP below 90% are definitely worth avoiding. The return rate from 94 to 96% is considered normal and potentially lucrative. Although, today you can find games even with such a tempting indicator as 98-99 %.

Let’s take a look at games that will most likely be the most popular slots online in October 2021.

10. John Hunter and the Book of Tut

The Mummy and Indiana Jones-style book slot saga will probably never go out of style. The Pragmatic Play company has come up with an old-school book slot game with traditional features and specs.
