We did all the hard work for you. It often goes around within the gambling community about what are the best online slots and the highest RTP slots. With so many titles, we can understand how it is difficult to make your choice and selection. We are sure you have most definitely heard, seen and possibly even played these titles before, so it would be good to rid you of all the confusion that comes with slots games you play. With each title that we recommend, we will overview the games summary and game genre, alongside with its RTP values for you to make an informed decision on whether or not this game deserves your attention.

What is RTP?

RTP is the return to player percentage that a player should expect to receive by playing a certain slot game online. It will define to a player how much they are expected to receive in the long term of playing the game. This percentage is taken by a pool of players that played the same game over a set period of time online. Therefore, it isn’t necessarily a representation of a onetime gameplay percentage at all.

You will definitely need to account for that and not make your decisions solely on the return to player percentage only. If you are wondering where you can find the return to player percentage within a game, it is usually located within the description of a game upon entering the casino site. We definitely would recommend you read the reviews that we provide separately for the games mentioned within our guide. You will find it helps also with making your decision on which game to actually go to play for real money, but also with real-life experience and reviews of a game-you get to see all the angles of the game beyond its return to player percentage.

Slot volatility

Slot volatility represents initially the risk of the game before entering and using it. There is a correlation also with the highest RTP slots and the lower the risk and volatility overall. The value of risk significantly decreases when the return to player is above the value of 95%, meaning definitely keep the value in mind, to make your judgment on the risk at stake every time you play the best online slots out there.

Also, slots with high volatility will be slots that do not necessarily pay out well in the process of your gaming. It is much higher to attain a payout, yet when you actually get a chance of a payout-it will be significantly high for you and your wallet. The low volatility slots, on the other hand, are completely opposite, meaning you will be entitled to more payouts on frequent occasions, yet you will be subjected to lower payouts within the process of it. So, if you have a goal of real money that you want to achieve on the top slots, you will have to work harder within the process of it all. It is up to you to decide what the best decision is for your casino gaming strategies.

Progressive slots have a lower RTP?

Often progressive slots are seen to be associated with big payouts, right? You will hear it on the news, where a player magically attained a winning jackpot of millions and therefore their lives have dramatically changed overnight. Yet progressive jackpots will always have lower return to players than other slot games. Why? Well, this is pretty much due to the large payout that a player can randomly occur-the top slots developer will then need to put money aside to ensure that they can gather a pool of money to payout this large amount that the progressive jackpot will give to players. For that reason, you will find that the return to player will then be reduced to ensure that the money can be safely stashed away!

So, if you want to play the highest RTP slots then progressive slots are not the go-to option for you to select. It will all come down to you as a player and what your goals are when playing online. If you want a serious chance at having a progressive jackpot win, then you might still keep playing in the hope of being the random lucky winner.
