In this Clover Casino blog post, we will discuss what the RTP is, how it’s calculated and some of the highest RTP slots.
What Is RTP?
The RTP (Return to Player) is a theoretical percentage that can indicate how much a slot is likely to return, or payout, over a long period of time on average. It may also help to think of the RTP rate as part of the money that is paid to play the game that is then returned back as prizes.
Say, for example, you are playing a slot game with a RTP rate of 96%. That means, in theory, for every £100 wagered, the slot may return £96 back in wins. The same idea could also be applied to a slot game that offered an 85% RTP. For every £100 paid into the machine, it may pay back £85 on average, over time.
However, the RTP is calculated over hundreds, if not millions, of simulated spins, so if you play a game for only a short time, the expected RTP rate may not be reflected in your playing session. You may win more than this, less, or nothing at all.
Additionally, slot games are entirely random games of chance due to the Random Number Generator (RNG), which ensures unpredictable and random results. This essentially means that winning can never be guaranteed.
99% - The Highest RTP Slots
The average RTP rate for slot games is usually between 95% and 96%. However, there are other slot games that may offer a higher RTP than that. Currently, the highest RTP rate in slot games is 99%.
Therefore, if you find a slot game with a RTP that is 99%, you are playing at the highest possible RTP rate on the market. A 99% slot game can be particularly appealing for players because it indicates a higher potential payout percentage.
However, always remember that this does not guarantee that you will win; it only indicates the overall potential payout over time for a specific slot game.
Best 99% RTP Slots List
Currently, there isn't an extensive number of slot games that offer a 99% RTP rate. But there are a few that have made waves among slot enthusiasts, and we will list a few below:
Mega Joker (NetEnt)
Mega Joker is a slot game developed by NetEnt. Its 3x3 grid layout has a classic theme that may resemble that of some Las Vegas slot machines, decorated with fruit symbols. While it does not have much in terms of bonus features, it offers 2 different playing modes, a maximum payout potential of up to 2,000x your stake, and a progressive jackpot.
Book of 99 (Relax Gaming)
The Book of 99 slot offers a 99% RTP rate, a Respins feature and a maximum payout potential of up to 5,000x your stake. This entertaining slot game also has a Free Spins feature and expanding Wild symbols that can potentially help you complete or create wins.
Jackpot 6000 (NetEnt)
Another slot game with a RTP rate of up to 99% is the Jackpot 6000 by NetEnt slot. It features an interface resembling a classic and retro fruit machine. This 3x3 and 5 fixed paylines slot game also offers a Supermeter bonus that can potentially award up to 6,000x your stake, resulting from the Joker symbol.
Ooh, Ahh, Dracula (Barcrest)
Ooh, Ahh, Dracula is a 5x3 slot game with 10 paylines and a RTP rate of 99%. As indicated by the name, it has a vampire theme but without the gore. Its symbols may also award up to 5,000x your stake.
Monopoly Big Event (WMS & Barcrest)
The Monopoly Big Event slot game by Barcrest is modelled after the famous Monopoly game. The graphics are similar to the classic it is themed after, and its RTP rate can reach up to 99%. Playable across 5 reels, 3 rows and 20 paylines, it features possible multipliers and a Free Spins feature.
1429 Uncharted Seas (Thunderkick)
The 1429 Uncharted Seas slot game offers a RTP rate of 98.50%, which just falls short of 99% but comes close, so we are giving it a mention.
This adventure-themed slot game features excellent and innovative graphics. It also offers expanding Wild symbols, which can potentially increase your chances of creating winning combinations, and up to 50 Free Spins.
How Is RTP Calculated?
As mentioned, the RTP rate can be calculated over time using a relatively straightforward formula.
The formula may look like the one below:
(Total Amount Returned / Total Amount Wagered) x 100
For example, say players have won a total of £9,500 on a slot machine in a specific period. And, in that same period, the slot has received £11,000 in bet amounts. Its RTP would be calculated as follows:
RTP= 9,500 / 11,000 x 100 = 86.36. Therefore, the RTP rate for this slot game would be 86.36%.
But, this example is only a simplified idea of what the RTP calculation process may look like. In reality, there are many factors that can affect how the RTP is decided, including the volatility of the game and, of course, the RNG software, to an extent.
Does Bet Size Affect RTP?
No. Bet size does not affect a game’s RTP.
For example, the RTP does not increase with your bet size. So, if you play a slot game with a 96% RTP with a £50 bet, the RTP will not increase; it will remain at 96%
Basically, the only thing a bet size affects is your potential payout because it is relative to your bet size. But, the RTP rate remains the same.
An RTP rate is an excellent indicator of how well a slot may do in terms of possible payouts. However, its accuracy can only be reflected after a long playing time. In addition, because of the RNG, players may win often or not at all because the results will always be random.
There is also the volatility to take into consideration, as it can also affect how often and how much the potential payouts are.
Please remember to always gamble responsibly.
