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.

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.

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.
