What is RTP?

Return to Player (RTP) is a term used to describe the percentage of all money wagered that a slot machine or casino game will return to players over time. This is a theoretical number calculated over a long period of play and represents the average return a player can expect from a particular game.

RTP calculation

RTP is usually calculated as the total amount returned to players divided by the total amount wagered by players. This calculation is usually expressed as a percentage, with the RTP typically in the 90% to 99% range.

House edge and RTP

House edge is the opposite of RTP. It represents the percentage of the total amount of bets that the casino or gaming operator keeps as profit. The higher the RTP, the lower the house edge, and vice versa.

Why RTP Matters

RTP is important for several reasons:

  • Informed Decision Making

Knowing the RTP of a particular slot machine helps players make informed decisions about which games to play. This information can help you find games that offer better chances of winning or at least minimize losses over time.

  • Fairness and transparency

Transparent RTP allows players to evaluate the fairness of the game. This is a way for developers and game operators to demonstrate that their games are not rigged and that they are following industry standards and regulations.

  • RTP Options

Not all slot games are created equal when it comes to RTP. There are generally three main categories of RTP bets:

  • High RTP Slots

These slots have an RTP of 96% or higher, giving players the best chance of winning over time. High RTP slots may have smaller individual wins, but they usually pay out more frequently.

  • Low RTP Slots

Low RTP slots have an RTP below 94%. These games tend to offer larger individual wins but pay out less often. They can be more risky for players as the chances of losing money are higher.

  • Slots with an average RTP

Slots with an average RTP are between 94% and 96%. These games strike a balance between the possibility of big wins and a decent payout frequency.

How to find RTP

Most online slot machines display their RTP in-game information either in the paytable or in the settings menu. In some cases, you may need to visit the game developer’s website or browse online casino review sites to find the RTP for a particular game.

RTP and volatility

It is important to understand that RTP is not the only factor to consider when choosing a slot machine. Volatility, also known as variance, plays a critical role in determining the level of risk associated with a particular game.

Discoveries with high unpredictability

Openings with a high degree of unpredictability tend to offer large payouts, however, such successes are less common. This means that players may face a longer dry season before making huge gains. These games are best for players with larger bankrolls and higher gambling tolerance.

Rooms with low instability

On the other hand, openings with low unpredictability offer more modest payouts but longer wins. These games are great for players with a small bankroll or people who prefer a more secure gaming experience. Gambling with quick loss of money is reduced, but the likelihood of big successes is also reduced.


Understanding the role of RTP in the web space is essential for gamers who need to make informed choices and improve their gaming experience. Given both RTP and unpredictability, players can find the perfect harmony between chance and reward and have a more enjoyable and exciting time at an online casino.

  1. What is a good RTP for an online slot?

A good RTP for an online slot machine is usually between 96% and 99%. However, remember to also consider the volatility of the game in order to make the best decision.

  1. Can I trust the RTP displayed by an online slot?

Reputable game developers and online casinos are required to comply with strict industry standards and regulations. While there is always the possibility of running into a rogue operator, using reputable and licensed casinos will ensure that the displayed RTP is accurate and trustworthy.

  1. Do progressive jackpot slots have a lower RTP?

Progressive jackpot slots tend to have a slightly lower RTP compared to non-jackpot games. This is because a portion of each bet is distributed to the progressive jackpot pool, which reduces the overall income of players.

The choice of places with high and low unpredictability depends on your own inclinations, bankroll and odds resistance. Opens with high volatility may offer bigger wins but less often, while areas with low volatility offer more modest and more regular payouts.
