PlayPlayNews 0

Playing online slots is a very popular pastime. The most popular of these slots are the ones that feature some sort of theme, rather than simply generic titles. Of course, there’s nothing wrong with generic slot games, as noted in TheInternetSlots.com AU, since many players find them more exciting to play. There was a time where online casinos would only have had one or two themed slots on offer for their customers to play, but now it seems like every other casino has at least one on offer.

The biggest and most profitable bonus that comes along with some of these slots is not just an increased payout percentage but also something that entertains the player while they’re playing it – which makes games seem less repetitive if you’re a veteran player looking for a bit more excitement/variety in their gameplay. Here are some of the most popular online slots in 2021.

  1. Avalon II
  2. Guns N’ Roses
  3. Mega Fortune
  4. Wizard of Oz
  5. Starburst

These are just five of the most popular online slots in 2021. There are many others available, and each has its own unique charms that will keep players entertained for hours on end. So, how do you know the best online slot to play in 2021? Below are four important factors you should keep an eye on when looking for the perfect online slot game to play.

The Theme/Graphics

One of the most important factors to consider when choosing an online slot is the theme or graphics of the game. This is because you want a game that will be fun and entertaining to play, and a game with bad graphics or a poor theme can quickly ruin the experience. So, make sure to choose a game with high-quality graphics and a theme you’re interested in.


The second most important factor to look at when choosing an online slot is the game’s RTP (return to player) percentage. This is a measure of how much money the casino will return to the player over time, and it’s usually listed on the games’ websites. It would be best to always look for a game with an RTP percentage of 96%+. However, pay attention to the maximum payout percentage, which is often lower than 95%.

The Gameplay

The gameplay of an online slot game is also very important. For example, you want to make sure that any game you choose is easy-to-play if you’re new to online slots in general. This means finding a game with simple controls and a straightforward design so that even if you don’t have much experience playing these types of games before, you’ll still be able to pick it up quickly.
The Bonus Features/Free Spins

When looking for online slot games, you should also consider the bonus features that come with each game. For example, free spins are some of the most popular types of bonuses these days, and they can lead to big wins if you get lucky. So, look for a game with lots of bonus features and good payouts so that every time you hit the spin button, it leads to a win or a larger payout than usual.

There are several slots to play in 2021 but what matters most is that you have fun playing the game. The games mentioned above are some of the most popular slots in 2021 for a reason – they offer great gameplay, graphics, and bonus features. So, be sure to try out a few of them and find the perfect one for you. Have fun!
