# 99% RTP Slots - Browse & Play The Highest RTP Online Slots

When choosing the best slot game to play, punters tend to look at the Return To Player (RTP) rate of the slot game. In broad terms, the RTP serves as an indicator of the proportion of the money taken in by a slot that it pays back out to players over a long period.

This post explains what an RTP rate means in slot games, what a good RTP looks like, how to find it and gives you a list of popular slot games with higher RTP rates.

## What Does RTP Mean In Slots?

RTP is an abbreviation for Return To Player rate, a percentage that measures the theoretical proportion of the money taken in by a slot game that it returns to players in the long run.

It is calculated as an average by the developers using a very large sample of spins. Think into the millions of spins.

So, in theory, the higher the RTP, the better the potential return. Let's say you have placed a bet of £100 on a slot game with an RTP rate of 96%. That means, over time, you may expect to receive £96, in theory.

That is why most punters want to look for slot games with an RTP rate as close to 99% as possible. None are going to have 100%; otherwise, casinos would never make money.

It is taken as an average due to the random nature of slots. So, shorter sessions may not reflect the RTP rate. Even the developers only find the value as what the payouts balance out to show over a very long period. Hence, a player's experience may not reflect the RTP rate.

## What Is a Good RTP For Slots?

The general rule is that a reasonable RTP rate for slot games is 95% and above. Slot games typically have RTP rates between 80% to 99%.

But, even then, the actual results you may get from playing the slot may not reflect the given RTP rate, but remember, the RTP rate is an average calculated over a very long time.

In addition, a slot game runs on a Random Number Generator (RNG). The RNG generates random and unpredictable outcomes every second to determine the array of symbols that will show at the end of a spin.

As a result, even if a slot game has a decent RTP rate, the RNG still determines the results.

## How To Find a High RTP Slot Machine

A slot game's RTP is one of the most straightforward information about a slot game to find. You can simply click the Information button or the Help button, depending on the slot game.

If you are struggling to find the RTP directly from the slot game's information, you can always Google the slot, and you are likely to find the slot's RTP rate. If you do this, always try to find the developer's site first for the most accurate answer.

## What Is The Average RTP On Slots?

Online slot machines tend to have an RTP rate of around 95%. The 99% RTP slots are a rarity, and even if you find them, be sure to check the RTP rate in the information section for the RTP rate at that specific casino.

We want to reiterate that individual slot gaming sessions can vary from the displayed RTP, which is just a theoretical indicator calculated as an average over millions of spins.

There may be some players who experience higher returns than the RTP indicates in a short period. In contrast, others may get lower than the RTP rate because slot games are inherently random and unpredictable, thanks to the RNG.
