What is RTP in Slots?

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.

What does RTP Mean in Slots?

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.

How is RTP Calculated?

RTP is calculated by taking into account several values. While it may seem like a complex process, calculating the RTP involves a mathematical formula that is relatively straightforward. Understanding how the RTP rate is calculated is crucial for any casino player looking to make the most of their experience by having a better understanding of how it works.

It is calculated by dividing the total amount returned to players by the total amount wagered by players and then multiplying it by 100. This calculation takes into account both regular wins and bonus features such as free spins or multipliers. On the other hand, the total amount wagered by players encompasses all bets placed on the RTP value game during a specific period.

For example, if players wagered a total of £10,000 on a particular slot game in a certain time frame and received £9,500 in winnings during that time, the casino’s RTP would be calculated by dividing the total winnings by the total wagers and then multiplying it by 100.

RTP = ($9,500 / $10,000) x 100 = 95%

How We Rate Top RTP Slots?

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.

  • First-Hand Testing – We first check the game’s reported RTP value and then we check the game first-hand to see if the reported RTP equates to the game’s performance and gameplay.
  • Comparing RTP to Standard – We verify the game’s RTP percentage and compare it to the industry standard, which, as I mentioned, is typically around 96%.
  • Player Feedback – We gather and analyse feedback from a broad spectrum of players to gauge satisfaction and reliability.
  • Comparing RTP to Volatility – We assess how the RTP aligns with the game’s volatility. High RTP with low volatility often means more frequent, smaller wins, while high volatility may offer larger, less frequent payouts.
  • Check RNG – We also make sure to check the slot’s RNGs and how they affect the RTP.

Advantages of High RTP Slots

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.

  • Increased Winning Potential – Higher RTP slots are designed to return a larger percentage of wagers over time, enhancing your chances of securing wins. This can be a great enhancement to the overall experience.
  • Reduced House Edge – High RTP naturally lowers the house edge, thus increasing your chances.
  • Improved Confidence – A high RTP provides confidence in fairness and reliability
  • Consistency in Payouts: High RTP slots tend to offer more consistent payouts. This can make it easier to manage your bankroll.

Things to Look for in High RTP Slots

Volatility

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 =.

Bonus Features

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.

Game Mechanics

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.

Maximum Win Potential

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 for High RTP Slots

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.

  • Free Spins Bonuses – Free spins are undeniably the most common type of slot bonus related to high RTP slot games. It is often offered as part of a welcome package or as an ongoing promotion, allowing you to spin the reels of high RTP slots without using your own money, increasing your chances of winning without additional risk. These are some of our favourites when playing the best RTP slot games, and one of the main reasons is that their availability – found at around 80% of casinos with high RTP slots.
  • No Deposit Bonuses – No deposit bonuses give you free credits or spins simply for signing up. This type of bonus is perfect for trying out high RTP slots without any initial investment, providing a risk-free way to explore the games.
  • Deposit Match Bonuses – These bonuses match a percentage of your deposit, effectively doubling or even tripling your bankroll. For example, a 100% match bonus on a £100 deposit gives you an extra £100 to play with. This increased bankroll allows for more spins on high RTP slots, maximising your winning potential.
  • Reload Bonuses – Reload bonuses are reserved for existing players when they top up their accounts and are some of the rarer offers found at 25% of online slot sites. These bonuses provide extra funds or free spins for continued play on high RTP slots.

RTP and Jackpot Slots

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.

High RTP Slots vs Other Casino Games

  • Bonus Features – Some slot machines offer multipliers, free spins, and specific mechanicso that can improve the overall odds.
