Explaining RTP In Simple Words

Let's start with the RTP acronym that stands for Return to Player. It's easy to find information that players can see in the paytable in these easy steps.

  1. Open the slot game to play with real money or in demo mode
  2. Usually, the menu icon features the paytable or a small "i" icon displays the slot game information
  3. The RTP of the slot is generally written at the end of the page or somewhere in the middle.

What does an RTP do?

It determines the percentage of the money players will get back from the bet they wager on the slot game.


Let's say you opt to play a slot game with a 97% RTP percentage. It means that for every £100 you wager on the game, you get back £97 over time.

How is the Return to Player Rate Calculated?

The main thing you have to remember about slot RTP is its average evaluation of the theoretical slot payout. There are two factors that players should consider when calculating the Return to Player percentage of the game.

  • Total Bet Amount: It's the total of every wager per round that players make over time.
  • Returned Amount: In simple terms, it's the player's winnings.

If you find this calculation complicated, we suggest using the RTP calculators online to give you the exact percentage of the slot game.

RTP Relationship With Volatility

Usually, RTP and Volatility are mentioned together, which make their association obvious; however, the two are not indicative of each other. Players often think that high RTP slots have low volatility. It may be true with some slot games, but it's not a hard and fast rule. Some slots like Wolfpack Pays feature high RTP and volatility.

When playing a slot game expert suggests keeping an eye on both metrics of the slot. Always check the statistics of the slot game that we often provide on Slots Racer for readers' convenience.

Low RTP Slots or High: Which is the Best to Choose?

When you scroll down the slot games list, you'll come across various RTPs, some high and some low. The question is, which is the best to choose? A one-word answer is HIGH as the high RTP slot offers a more significant return percentage of players' bet amount.

The RTP level is not your only concern when evaluating the statistics of the slot game; volatility also plays a vital role in slots performance. You will come across slot titles like 1429 uncharted Seas with a high RTP of 98.50% but low variance. Immortal Romance by Microgaming is a highly volatile slot game with high RTP. The choice depends on players preference because with high volatility comes low winning frequency but bigger prizes; however, with low volatility winning frequency increases, but the prize value decreases.

Overall if you like to play slow and steady, we suggest low volatility slots like Starburst. If you consider yourself a high roller, we offer highly volatile slots like Medusa Megaways for a chance to win big.

Can you rely upon the Return to Player Metric?

You choose a slot game with high RTP, is there a guarantee that it will return more of your bet? From a theoretical point of view, the answer is YES. However, the mechanics work differently in practice, especially when players play short game sessions where RTP doesn't come into play effectively. On the other hand, the harm of slot machines is their random outcome that no one can predict.

When playing short sessions, the chances are you will not get your wagering amount back but also double or triple your bet amount. We can safely suggest that playing games with higher RTP are always a good choice.

A rumour often circulates among naive players that RTP is nothing in value, and slot games are often rigged. It's not a complete truth, no doubt there are online casinos that feature copies of slot machines without any official RTP, or they use RNG technology for fair play. But such online sites are few, and to avoid such scams, always play games through reputable online casinos like Slots Racer. We offered our players a safe and legit gambling platform regulated by robust regulatory bodies. We operated with RNG and SSL encryption technology that provide fair play and safety at the same time.
