FAQs About Highest RTP Slots:

How do slots with the highest RTP help you win?

As earlier mentioned, the return to player percentage shows how much of the wagered funds get paid back to the players in winnings. If $1000000 is wagered on a slot that has RTP 98%, there will be $980000 to be shared among the winning players.

In contrast, if the same amount is wagered on a slot that has a RTP of 97%, winning punters will only have $970000 to share. From this, you can see that the best online slots payouts allow you to claim more in rewards. 

What is the difference between theoretical and actual RTP?

A slot’s theoretical RTP is displayed as a percentage. You will find it in the section providing more details about a particular title, and it serves to inform you how much you can theoretically win.

On the other hand, Actual RTP is a title’s actual payout as per your session, and its value is different from the theoretical return to play a percentage.

How can we prove the RTP is correct?

As a player, the only way you can determine if the return to player percentage of a game is correct is by playing long sessions in which you will have to track both your spending and the payouts you receive.

How do you find a slot’s RTP?

To enjoy the best slot games, you will have to find the return-to-play percentage of an individual slot, and you can do this by clicking on the slot then reading its details.

Volatility vs. RTP?

While the return to player % specifies how much you should expect to win in the long

run, the term slot volatility refers to the inherent risk that comes with playing a particular title. It also determines the frequency of your winning.

Slots with high volatility are very risky, meaning you can lose lots of cash in the process but when you strike a win, you also win big.The winnings are also spread out and far in between.

If you are on a budget, always go for low to medium volatility. You’ll have small but frequent wins that will make your gaming sessions entertaining. But if you are a high roller with a large appetite, risk, and budget, try the high volatility slots. You could strike the jackpot and be the next millionaire in town.

Bottom line?

High or low volatility, always go for slots with high RTPs.

Why do Progressive slots have lower RTPs?

Unlike Ted RTP, which is at 95.8%, most progressive slots have lower RTPs. This is because they are part of an extensive network of slots, and several players have to play to contribute to the slot’s jackpot winnings. 

Besides, these jackpots involve paying out large amounts of money to the winners, and one of the ways casinos can afford to make that happen without totally losing out is by lowering the RTP.

Final Word on the Highest RTP Slots: Are They Worth It?

All games have rules; even games of chance like slots. In slots, picking the right ones is a step closer to winning; both cash rewards and massive entertainment.

So, now that you know that finding slots with the best payouts isn’t that hard and that playing the highest RTP slots will increase your winning chances, it’s time to take action.

And the best part?

There is a slot for everyone. They come with different themes, bonus features, symbols, presentations, and even winning ways. Just pick one, make sure it has the highest RTP, pick a casino with the best payout, claim a free spin, and go!
