Online Slots RTP Guidelines

Even the most dedicated slot player may have to Google “what is RTP?” A basic understanding of this concept is essential to your success in any online slot game at, and we’re here to help you make sense of it.

What is RTP

The Return to Player (RTP) is a mathematical formula used to represent the theoretical profitability of a gambling machine. The game creators calculate the RTP slot number after thousands of spins to ensure accuracy. As an illustration, a slot machine with a 96% return to player percentage will, over time, payout £96 for every £100 wagered. We use the word “eventually” because the reported amount over £100 will not always be accurate.

Understanding the RTP

Although it may appear complicated initially, understanding payout percentages is rather simple. Simply put, the payout percentage for a given game is the proportion of stakes returned to winning players at the end of the session. These figures are simply provided as a guide for players to know what their typical winnings might be. 

If you’re looking for a game’s payout percentage, you might see it as the game’s “return-to-player” (RTP) percentage instead. The Return to Player (RTP) of a casino game often falls between 80% and the upper 90% range, though this does vary widely by both the game and the casino.

If the RTP is 96%, then the casino will pay back an average of £96 to players for every £100 they gamble. But this doesn’t mean everyone should expect the same return on their investment. This payout % is averaged across a large sample size rather than calculated for a single player’s performance over an hour.

A player may have to play thousands of games or spins or play hundreds of thousands of hands before finally experiencing the claimed return to player percentage. It’s better to think of it as the average amount a slot machine or casino game will pay out to all of its players over a long time. The payout structure for each participant will be unique. Some people may have a winning streak, while others will lose all of their money.

Remember that the RTP does not represent the frequency with which a player can win a certain game. Given that frequent wins are smaller and less frequent wins are larger, the RTP average will be satisfied over the long run regardless of wagers and the size of any winning combination. On Roulette, for instance, if you stick to placing even money bets instead of risking your money on a single number at 35:1 odds, you will have a far higher chance of winning.

Learn about the RTP laws in the UK

While RTP regulations will vary from country to country (or, in the case of the United States, from state to state), those in the United Kingdom are easy to understand and follow. There is no minimum RTP restriction like in some US jurisdictions; thus, developers and casinos can make it as high or low as they choose. 

The UK Gambling Commission mandates that all casinos within its jurisdiction make the RTP for any game easily accessible. This applies to both online and offline casinos. In a land-based casino, the RTP will be posted on the game, and online, it will be in the game’s instructions or help menus. RTPs for slots and games like the strength training weapon, vary from casino to casino. Check the RTP even if you’ve played the game before.
