Most Popular Online Slots Games for 2021


If you have any experience spinning reels on the internet, you know that most online slots generate a ton of interest following their release, and then they fade into obscurity. That is because there are over 17,000 online reel spinners. Thus, the market is highly saturated, and the slot format does not allow for a ton of novelty.

Most of the titles that maintained their popularity either tie into a promotional deal or feature the right combo of rudimentary gameplay and enticing prizes. For example, the answer to the question – what is the most popular online slot game is simple. That is NetEnt’s StarBurst, a low variance, five-reel, three-row game. In the text that follows, we will list the most popular slots games for 2021, tips on how to win at them, and rattle off the best online slots sites.

Most Popular Online Slots Games for 2021

We are a little over the halfway mark in 2021, and over 1,200 new reel spinners have hit online casinos. So, if you want to know what are the best online slots to play that have a 2021 release date, here are three titles that have managed to attain sizeable interest from newbie and veteran players:

  • Primate King – This is a Red Tiger release that attempts to capitalize on the buzz for the movie Godzilla vs. Kong. It is a high variance game that uses a five-reel, four-row layout and accepts penny bets. Primate King’s RTP is 94.6%, and its max exposure is x3,800 (max bet – $10).

  • Safari Sam 2 – Safari Sam 2 is a medium variance Betsoft game, a sequel to their legendary 2012 release.

Tips to Win at Online Slots

If you are wondering – how can I win at online slots? Well, the truth of the matter is that random number generators indiscriminately determine all slot spins. So, there is nothing that you can do to affect the symbol combinations that come up on individual reel rotations.

Do not get discouraged by the statement above. While it is accurate that gameplay-wise, you can do little to improve your odds of winning, there are other ways you can make sure that you get the most bang for your buck at online casinos. These are:

  • Play Low Variance Slots – You can find hundreds of lists for the best online slots for real money. However, what you should be looking for are low variance titles. These are games that frequently pay out small rewards. They are the best option if you want to stay ahead of your operator and out of the red.
  • Use a Betting Strategy – Yes, slots are super simple to play. You only need to press a button. So, the way to try to beat these games lies in how you approach the process of betting on them. The Martingale is a popular system that involves doubling your bet following a loss. To implement it, you will need to find a slot that has a wide betting range.
  • Take Advantage of Bonuses – Bonuses get you free gambling funds. No deposit deals let you play for free without a deposit, and they are the most sought-after offers in the interactive gaming space. While you should always keep an eye open for them, such a deal may not be easy to find. So, taking advantage of a generous welcome package should be your main priority.

Where to Play Online Slots for Real Money

According to the American Gaming Association, there are over 2,800 gambling sites in existence. Therefore, the process of picking one that is suitable for you may be a bit of an arduous task. We suggest that you select one of the following three vetted platforms:

  • BetUSBetUS is one of the internet’s original sportsbooks, founded in 1994. It has two gaming licenses from Costa Rica and Curacao. The slot catalog at BetUS consists of over 300 titles.

To Wrap Up

Can you win money playing online slots? Of course, you can. The process of spinning reels on the internet is the same as at a land-based venue. The main difference is that online slots feature far more advanced graphics and gameplay mechanics.

Nothing will help you attain better symbol combinations on their reels. So, the trick to walking away with more than you had when you sat to play is picking games that are a good fit for you and implementing betting systems. Also, never overstep your means. Remember, gambling responsibly is paramount for your emotional and financial well-being.
