What Is Return to Player (RTP) & Why Does It Matter?

RTP is an acronym that stands for Return to Player. It’s the percentage of money that you win versus what you gamble over time. Every slot game has an RTP percentage based on thousands of simulated outcomes. Slots with RTP percentages over 98% are pretty rare.

The standard/average RTP is often between 94% and 96%. In other words, you really have to narrow down your search to discover slot games with the highest RTPs. With high RTPs, the payouts also occur a lot more frequently, which is very encouraging.

The downside, however, is that life-changing cash prizes are a lot rarer with these games. Slots with progressive jackpots and megaways are better if you’re seeking a massive payout. Remember that a slot’s RTP indicates what you’ll potentially win over an extended period of time.

If the RTP is 99%, there’s no guarantee that you’ll win $99 back after you gamble $100. Ultimately, you should use RTP as a metric of what’s winnable in the long run.

Lower Frequency of Big Wins

Unfortunately, slot games with high RTPs won’t reward you with massive wins very often. Instead, payouts will occur more frequently but in lower values.

Fewer Slots to Choose From

Less Future Game Innovation

Unfortunately, almost every new and modern slot title doesn’t have an RTP exceeding 97%. Instead, you’ll have to stick with the older games that have outdated graphics. Also, various gaming innovations — interactive features, realistic sound effects, etc. — are often absent.

We also want to guide you on how to play the highest RTP slots. There’s no definitive strategy that you can implement to guarantee the best possible outcomes. However, we also urge you to control the things that you can control.

Understand the RTP and Volatility

RTP and volatility are major factors that have an impact on what you win. With higher RTPs, there’s a greater guarantee that you’ll win more money over time. For example, if the RTP is 98%, that means you’ll receive $98 for every $100 you gamble (on average).

Volatility refers to the level of risk and unpredictability involved in slot games. It’s different from RTP because it accounts for other factors, such as the frequency and size of every payout. With high volatility, there’s greater risk — but also greater rewards.

We also have a guide on slot machine odds, which explains everything. You’ll find information on probabilities, average payout percentages, the number of paylines, and more.

Practice Bankroll Management

Bankroll management is very crucial when it comes to responsible online gambling. Like every other player, there’s only so much money you can spend before you reach your limit. That’s why you need to establish a daily, weekly, and monthly gambling budget.

Take Advantage of Bonuses and Promotions

Many bonuses and promotions are also available to you. Whether you’re a new or active player, there’s always an opportunity for you to boost your bankroll. You can take advantage of free spins, cashback offers, reload bonuses, and other promotions.

Don’t Chase Losses

Losing can happen to you at any time while playing slot games. The truth is that there’s no skill involved — you win based on luck alone. That being said, you should know when to walk away and avoid making the situation any worse.
