Negatives of 99% RTP Slots
No casino game is perfect, and 99% RTP slots are no exception. To help you make an informed choice, we’ve outlined some potential downsides:
❌ Limited Choice: The variety of 99 RTP slots is relatively small, as providers often hesitate to release many games in this high-payout category. While enjoyable, the limited selection can lead to repetitiveness.
❌ Casino Bonus Wagering: Meeting wagering requirements is essential for converting online casino bonuses. However, high RTP games often contribute less towards these requirements, making it challenging to take advantage of such offers.
What is RTP in Slot Games?
RTP represents the percentage of total bets a slot machine will return to players over time. It’s something developers decide upon before release and then simulate billions of spins to ensure a game’s theoretical RTP and actual RTP match up over the long term. Take, for example, a slot game with an RTP 99%. This means, theoretically, you should expect £99 back for every £100 wagered. However, this is an average calculated over countless spins. Short-term play might see variations from this percentage.
Something that we should point out though is that online slots can come with a multi-RTP setup. This means there are different versions of the game, generally for different markets, that will have different RTP percentages. So, because of this, we strongly advise you to check which version is available at your chosen casino before playing. All you’ll need to do is load up the game and take a look at the information panel, the RTP should be listed.

The Most Common RTP Ranges for Slot Games
Typically, slot game RTPs (Return to Player) range from a low of 90% to a high of 99%, with the average hovering around 96%. If you’re interested in exploring a variety of slots that still offer favourable RTP ranges, be sure to check out the following options:
Difference Between Volatility and RTP
Understanding the difference between volatility and RTP is crucial as they have a huge impact on the resulting gameplay of any online slot. While RTP estimates your theoretical returns over time, volatility indicates the frequency and size of payouts: low volatility means small, frequent wins and high volatility leads to larger but rarer payouts.
If you play a low RTP but highly volatile slot, you’re facing a higher risk. Conversely, a high RTP slot with low volatility can yield impressive results. Below, we’ve detailed the differences between volatility and RTP in a table for clarity.
Volatility | RTP |
---|---|
Refers to the expected frequency and value of payouts | Refers to the theoretical returns a game will award |
Evident in the short-term | Only evident in the long-term |

Your 99% RTP Slot FAQs Answered
Still have questions about these high-payout slots? Our FAQ section covers everything from their worthiness to specific game recommendations.
A 99 RTP slot is a slot game that has a Return-to-player rate of 99%, meaning it returns £99 for every £100 wagered over time.
99% RTP is a figure that applies to certain online slots that are theoretically the best games to play online. That’s because the value relates to a game’s expected payout rate over the long term, so the higher it is, the better.
If you want to give yourself the best chance of winning, slots 99 RTP are certainly worth playing. Statistically, they have the best-expected payout rates of any type of online slot. Remember though, RNG and luck play a pivotal role in any spin. Therefore, even though the odds might be slightly more favourable, there’s no guarantee that you’ll win.
When it comes to recommending the best slots, it’s difficult to pick one specific option. That’s because a game’s appeal comes down to individual preference. What one player might love, may not appeal to another. Still, we think Relax Gaming’s Book of 99 is a great 99% RTP slot. It’s modern, it has some great bonuses and it has great payout potential.
The size of your bet has no impact on a game’s RTP. To illustrate, betting more doesn’t boost the RTP. Therefore, if you wager £50 on a slot with a 96% RTP, the RTP stays constant at 96%. In essence, your bet size only alters the possible payout, as it’s proportional to your wager. However, the RTP percentage remains unchanged.
No. It’s a common misconception that online casinos can alter the RTP of slot games on their platforms. In reality, the slot games are hosted on the developers’ servers, making it impossible for casinos to modify their RTP statistics.
