What is RTP?

RTP, or Return to Player, is a key metric in slots, indicating the payout percentage a player can expect over a multitude of spins.

This metric, usually presented as a percentage, reflects the average amount of wagered money a slot game returns to players as winnings.

For instance, a slot with a 95% RTP means that for every $100 wagered, it pays out $95 over time. High RTP slots are sought-after because they theoretically offer better chances for winning.

Conversely, a lower RTP suggests a higher edge for the house, making wins less frequent. It's crucial to remember that RTP is calculated over the long term, so short-term play can see significant variance.

Games with the highest RTP rates are particularly appealing to players aiming for the best potential returns. However, it's also important to balance RTP with other factors like game volatility, which affects the risk and reward profile of the slot.

There is also the house edge, an essential concept in casino gaming. The house edge is the opposite of RTP and represents the casino's profit margin on a game. A higher RTP means a lower house edge, indicating better potential returns for players over the long haul.

How is slot RTP calculated?

Calculating the RTP of casino slots involves a complex process that considers the total amount returned to players as winnings against the total amount wagered by players.

Essentially, it's a mathematical formula used by online casinos to determine the percentage of wagered money a slot machine will pay back over time.

For slot players, understanding this calculation is key to assessing the potential value from gameplay and better manage their bankroll.

To arrive at the RTP, developers run simulations within the game. Casinos and game developers publish RTP percentages to provide transparency and help players make informed decisions.

Remember, a higher RTP doesn't guarantee wins in the short term but indicates a game designed for better returns to players over extensive gameplay. Also remember that slots are created with the Random Number Generator (RNG), so an easy and secure win is never guaranteed.

How can you calculate a slot's RTP?

To calculate a slot's RTP, you cannot do so directly as a player. Instead, you find it listed in the game's information section provided by online casinos or on the game developer's website.

Where you can find the RTP of a slot?

You can find the RTP of a slot in the game's information tab on online casinos, on the slot developer's website or in a slot’s paytable.

Slot RTP vs other casino games RTP

Slot RTP and the RTP of other casino games, such as table games like roulette and blackjack, differ primarily in how they are calculated and what they imply for player percentage.

Slots often feature a fixed RTP, which gives a theoretical percentage back to players over an extended number of plays, usually ranging from 92% to 98%. This player percentage is influenced by the game's volatility and casino bonus features, which can affect the actual winnings over short periods.

On the other hand, table games like roulette and blackjack have RTPs that can vary more significantly based on gameplay strategy.

For example, blackjack's RTP can be as high as 99.5% for players using optimal strategy.

Roulette's RTP varies depending on the version. European roulette offers a 97.3% RTP, while American roulette offers a lower RTP due to the double zero feature.

The key difference lies in the player's ability to influence the outcome. Online gambling with table games allows for strategic play that can directly impact RTP, a feature not present in the random outcome of slot spins.

Best RTP slots

For players aiming for the best chances at a big win with real money, selecting the highest slot game’s RTP is a good option.

Here's a list of 5 top slots known for their generous payout rates:

  1. Mega Joker by NetEnt (99% payout rate): This classic slot stands out with one of the highest RTPs available, offering a near-even chance against the house.

What RTP rate should have a slot to be good?

A slot is considered good if it has an average RTP rate of 96% or higher.

RTP vs Volatility

RTP and volatility are two critical concepts in slots that, while related, serve different functions.

RTP represents the percentage of total wagers that a slot returns to players over time, serving as a long-term indicator of a game's payout potential.

Volatility, on the other hand, measures the risk associated with playing a slot and how often and how much it pays out. High volatility slots yield big wins less often, suited for risk-takers. Low volatility slots offer smaller, more regular wins, ideal for players desiring consistent gameplay.

The correlation between RTP and volatility lies in their combined impact on the gaming experience.

RTP indicates potential returns, while volatility affects payout patterns, aiding in selecting games suited to your risk preference and play style.

For instance, a game with high RTP and low volatility is generally perceived as offering the best of both worlds, consistent returns and lower risk. However, it's crucial to remember that neither metric guarantees wins on any given spin or session, as outcomes in individual sessions are subject to chance and the game's payline structure.

Why is RTP important to consider?

Considering RTP is important because it informs players about the potential return from a slot over time, helping to manage expectations and select games with better chances of winning.

Is RTP a real thing in slots?

Yes, RTP is a real thing in slots, representing the percentage of total bets that are returned to players over time.
