Many terms and concepts are important for every gambler to understand in online gambling. One of the key metrics to pay attention to when choosing slots is the return to player, or RTP.

RTP is a theoretical indicator expressed as a percentage. It shows how much of the total amount of bets the slot returns as winnings in the long run.

For example, if the RTP of a slot is 96%, it means that, in theory, out of every $100 bet by players, $96 will be returned as payouts.

Understanding the nature of RTP is critical for several reasons:

  • Assessing potential profitability: RTP shows how "generous" a slot can be in the long run.
  • Comparing games: Knowing the RTP of different slots allows gamblers to choose those that offer more favorable conditions.
  • Expectation Management: RTP helps create realistic gameplay expectations and possible winnings.
  • Strategic Planning: Information about RTP can be used in strategy and bankroll management.

In this article on Casinoz, we examine the concept of return to player, its impact on gameplay in online slots, and how gamblers can use this information to make more informed decisions when playing.

What Is RTP in Slots?

Let's clear out this concept in detail.

Return to Player (RTP) is a crucial concept in online casino slots. It represents the percentage of all wagered money a slot machine will pay back to players over time.

Essentially, RTP measures a slot game's generosity and is a key indicator of its long-term performance.

It is important to realize that this is a long-term and theoretical figure based on millions of spins. It does not guarantee a particular player a certain percentage of funds will be returned during a gaming session.

For example, if a slot's RTP is 96%, this means that over a very long period of play, the slot should return 96% of all bets placed to players. The remaining 4% represents the casino's theoretical advantage, or the house edge.

The formula for calculating RTP: RTP = (Total Payouts / Total Wagers) x 100%.

To determine the RTP game developers use complex mathematical models and algorithms, as well as conduct millions of simulations of gaming sessions. The resulting value is then verified by independent auditing companies to confirm the claimed figure.

It is important to note that RTP does not reflect the frequency or size of individual wins. It merely shows the overall trend of returns to players over the long term.

Understanding RTP helps players evaluate the potential profitability of different slots and make more informed choices when playing. However, it should be remembered that the actual results of individual gaming sessions may differ significantly from the theoretical RTP due to short-term volatility and the element of randomness inherent in gambling.

Typical RTP Ranges

Understanding the typical RTP ranges for online slots helps players gauge what constitutes a good return rate. Let's explore the average RTPs and compare them with land-based casinos.

Average RTP for online slots:

  • Online slots generally offer RTPs ranging from 92% to 97%.
  • Many popular online slots fall in the 95% to 96% range.
  • Some high-RTP slots can reach 98% or even 99%, though these are less common.
  • Slots with RTPs below 94% are generally considered low for online games.

RTP tiers for online slots:

  1. Low: Below 94%,
  2. Average: 94% to 97%,
  3. High: Above 97%.

Comparison with Land-Based Casinos

Online slots typically offer higher RTPs than their land-based counterparts.

Physical casino slots often have RTPs between 70% and 90%.

The lower overhead costs of online casinos allow them to offer more favorable odds.

Factors Influencing RTP Differences

Why do slots feature different returns to the player?

  • Operating costs: Online casinos have lower expenses, allowing for higher RTPs.
  • Competition: The online market is more competitive, pushing RTPs higher.
  • Regulations: Some jurisdictions have minimum RTP requirements for online slots.
  • Transparency: Online RTPs are often published, encouraging higher rates.

While online slots generally offer better RTPs, this doesn't guarantee better outcomes for individual players in the short term. The higher RTP becomes more significant over extended play periods. 

Factors Affecting RTP

While the Return to Player (RTP) percentage is a fixed value for each slot game, several factors can influence how this plays out in practice. Understanding these factors can help players make more informed decisions about which slots to play.

  • Game volatility: Volatility (or variance) refers to a slot's risk level and payout frequency. High volatility slots tend to have less frequent but larger payouts, while low volatility slots offer more frequent but smaller wins. Volatility can affect how a player experiences the RTP in shorter play sessions. High-volatility games may require longer play times to approach their stated RTP.
  • Bonus features: Many slots include bonus features like free spins, multipliers, or mini-games. These features often contribute significantly to a game's overall RTP. Some slots may have a lower base game RTP but compensate with high-value bonus rounds. Understanding how bonus features contribute to RTP can help in game selection.
  • Betting strategies: Some slots have different RTPs for different bet sizes. Maximum bets may sometimes activate additional features or paylines, potentially increasing the effective RTP. Progressive jackpot slots often require maximum bets to be eligible for the jackpot, which can significantly impact the overall RTP.
  • Game mechanics: Certain game mechanics like cascading reels or expanding wilds can influence how the RTP is experienced.
  • Paytable structure: The distribution of payouts across different symbol combinations can affect how the RTP manifests in gameplay.
  • Game provider: Different software providers may have varying approaches to RTP implementation.

While these factors can influence how RTP is experienced, they don't change the game's underlying mathematical RTP. Players should consider these elements alongside RTP when choosing slots to play.

Here are some high-volatile slots.

How Can I Figure out a Slot's RTP?

There are two ways to calculate the RTP, but none works for slot machines at online casinos. The first method involves mathematical calculations. The most straightforward example is making bets on European Roulette.

  • There are 37 numbers on the wheel.
  • Eighteen are black.
  • The odds of hitting a black number are 18:37.

It is simple.

However, using this approach in online slots is impossible because we do not have enough information for calculations. To do this, we need to know the number of symbols of each type that may land on the reels.

But even if we get all these data, the calculation will be too complex for an average user without special education, as they must be aware of many nuances, such as the number of pay lines and winning combinations, bonuses, etc.

Computer software simulators estimate the return to players of particular games in such complex cases. They are often used in video poker and blackjack. They simulate tens and hundreds of thousands of hands, and the program processes the results.

Despite this method's apparent advantages, applying it to online slots is difficult because of their vast and ever-increasing diversity.

We know only a dozen varieties of blackjack or video poker; new slots come out daily.

Consequently, if a third-party researcher has a goal to calculate the RTP of each slot, he won't be physically able to do it.

You can research the RTP of online slots using autoplay in a free mode. Such an opportunity is available at most online casinos. To do this, set the bets and start the autoplay at the maximum number of spins. You can calculate the return if you know the initial and final amount of the bankroll, the number of spins, and the bet.

But we should not delude ourselves about the accuracy of the result. Even a few thousand spins are not enough for such calculations. So, this practice will be better suited to practice on a selected slot but not choosing the best one in terms of payments.

Misconceptions about Slot RTP

Despite its importance, RTP is often misunderstood by players. Let's address some common myths and clarify the relationship between RTP and house edge.

Common myths:

  • Myth: High RTP guarantees wins.

Reality: RTP is a long-term average and doesn't guarantee short-term results. You can still lose money on high RTP games.

  • Myth: RTP changes during gameplay.

Reality: The RTP of a slot is fixed and doesn't change based on recent results or player behavior.

  • Myth: Casinos can adjust RTP at will.

Reality: Reputable casinos use games with fixed RTPs set by developers. Changing RTP typically requires regulatory approval. Yet, some providers offer slots with several RTP levels, and casino operators can choose from them.

  • Myth: RTP indicates how often a slot pays out.

Reality: RTP doesn't reflect payout frequency, which is more related to volatility.

  • Myth: Lower RTP games are "due" for a big win.

Reality: Each spin is independent. Past results don't influence future outcomes. Though understanding RTP is valuable, it's just one aspect of responsible gambling. Always play within your means and for entertainment purposes.

Remember, the key to enjoying online slots is to play responsibly, within your means, and primarily for entertainment. RTP is a useful guide, but it should never overshadow the importance of safe and enjoyable gameplay.
