RTP is a fundamental concept in the world of online slot machines, and it stands for Return to Player. It refers to the percentage of wagered money that a particular slot machine will pay back to players over time. This value is crucial as it helps players understand their potential winnings and make informed decisions about which games to play.
RTP means the long-term average payout. For example, if a game has an RTP of 95%, it means that for every £100 deposit, players can expect to receive £95 back in winnings on average. It’s important to note that this percentage is calculated over a large number of spins on the casino site and does not guarantee immediate returns or bonus rewards. Because of this, it is often referred to as Theoretical RTP.
RTP directly influences a game’s payout. A higher RTP means the game is programmed to return a larger portion of the total bets over time, resulting in theoretically more frequent or substantial payouts. Conversely, a lower RTP indicates less frequent or smaller payouts. Thus, RTP is a key factor in assessing a game’s payout potential.
When it comes to the world of online slots, the average RTP value in the industry is considered to be around 96%. However, there are also many slot games that offer RTP percentages above this threshold, thus providing a potentially more rewarding experience.
RTP is calulated with a simple formula that can be crucial to slot players. However, before an RTP can be attributed to slot games, they need to be played extensively. A study by UKGC (UK Gambling Commission) showed that to allow for accurate payout rates that millions of spins need to happen and even then they could still vary by 1-2%. This is due to the volatility of slots, compared to a table game with a low house edge like blackjack.
The actual calculation for RTP is simply dividing the money won by a player by the amound they wagered. Then, to get the percentage, you multiply by 100. For example, if you wagered a total of £10,000 on a particular slot game over a set period of time and received £9,500 in winnings during that time, the RTP would be calculated as follows:
RTP = ($9,500 / $10,000) x 100 = 95%
When it comes to rating the best RTP slots in the UK, we don’t just look at the RTP value and call it a day. We actually do more thorough research and detailed checks to see if the game is a good choice. Let’s take a look at what aspects we consider.
Unlike other aspects of slot games, choosing to play high RTP slots in the UK doesn’t have any considerable disadvantages, and you can only look forward to perks and benefits. After all, the higher the RTP, the more likely it is for the game to pay out. Let’s go over them in more detail.
Volatility is a crucial aspect of high RTP slot games and one that is very tightly entwined with a game’s RTP value in general. Volatility indicates the risk and payout frequency, while RTP shows the theoretical payout over time. Low volatility can indicate more frequent yet smaller wins, while high volatility usually provides less frequent but bigger wins. You need to look for games that provide a nice balance of both RTP and volatility =.
Look for high RTP slots with engaging bonus features, including free spins, multipliers, wilds, and bonus rounds. These can significantly enhance your winning potential and the overall entertainment value of the game.
Check the slot’s mechanics, such as paylines, reel setup, and special symbols. Many new high RTP slots in the UK are made with Innovative mechanics like Megaways, cascading reels, Gigablox, Cluster Pay systems, Infinity Reels, and so much more. These can add excitement and variety to the game, as well as increase the chances of winning.
Assess the slot’s maximum win potential. High RTP slots with substantial maximum payouts can offer the best of both worlds – a good return on investment and the chance for bigger wins.
Casino bonuses can often be the perfect choice when choosing to play the highest RTP games in the UK, as they can provide even more opportunities for big wins. Let’s go over some of the most popular types of casino bonuses that you can claim for high RTP slots and explore them in more detail.
Jackpot slots, particularly progressive ones, have unique RTP characteristics that set them apart from regular slots. Typically, these slots feature a lower base RTP because a portion of each bet contributes to the jackpot pool, slightly reducing the percentage allocated to regular payouts. Jackpot slots often exhibit higher volatility, meaning regular wins might be less frequent, but the possibility of hitting a substantial jackpot adds excitement and potential for huge payouts. Some jackpot slots offer fixed jackpots, making the RTP more predictable.
Understanding that the overall RTP includes the rare but significant jackpot win helps set realistic expectations. While jackpot slots may have a lower base RTP, the inclusion of the jackpot potential can make them highly appealing, especially for players chasing life-changing wins.
