Why RTP Can Mislead Slot Players

If I told you a slot had a 96% RTP, what would you expect to happen if you sat and spun your way through £100? Most people would reasonably assume they'd get about £96 back, but they probably wouldn’t.

Why RTP Can Mislead Slot Players

Why RTP Can Mislead Slot Players

RTP is one of the most common misconceptions in online gambling businesses. While it’s accurate - by law it has to be - it’s not necessarily precise, and it certainly doesn’t apply to the vast majority of slots sessions.

RTP Isn't a Promise, Exactly

RTP stands for Return to Player. It represents the percentage of stakes a game is designed to return - over an extremely large number of spins. If it’s helpful, you can think of it as the opposite of house edge, so a slot with a 96% RTP has a house edge of 4%.

The problem is, RTP is affected by four main things:

  • Number of spins
  • Volatility 
  • Hit frequency
  • Whether the slot is a progressive jackpot or not

This, combined with the RTP figure, means that one player could lose their balance within minutes and another could hit the bonus feature on their second spin and finish hundreds or even thousands of pounds ahead.

Both experiences can occur within the same game, designed legally and fairly around exactly the same RTP figure. One of the best ways I’ve ever heard to describe RTP is that it’s more like a long-term weather report than a daily weather forecast.

Brighton receives around 855mm of rainfall each year. That's useful information if you're deciding whether to move there. It tells you almost nothing about whether you'll need an umbrella this afternoon.

RTP is really helpful for understanding a game's design over millions of spins. It's far less useful when trying to predict what will happen during tonight's session.

Higher RTP Doesn't Automatically Mean Better Value

Many players have been taught to chase the highest RTP. If one slot returns 97% over the long term and another returns 95%, surely the first is automatically the better option… not exactly.

If RTP were the only thing that mattered, everyone would simply sort casino lobbies from highest to lowest and play whatever appeared at the top of the list. The fact is, they don’t.

That's because two games with identical RTP figures can produce completely different experiences. Here’s why.

Hit Frequency

There’s nothing more demoralising than blowing through your entire bankroll in a few minutes, when a slot with a solid 96% or higher RTP ends up just refusing to play ball. Why does this happen?

Hit frequency varies loads between games, and it means that one person might see no wins at all, and another might hit a large win quickly - that’s on a slot with a low hit frequency.

On a slot with a high hit frequency, you’ll probably get a few wins, even during a short session. The RTP in both of the games remains identical. The feel of the playing session is totally different. 

Volatility

Volatility and hit frequency are often used interchangeably, and while they’re very close, there is a difference. Hit frequency tells you how often you're likely to win. Volatility tells you how those returns are distributed.

A high-volatility slot tends to concentrate more of its RTP into larger, less frequent payouts. That's why these games can feel brutal during shorter sessions - you’ve got to be able to ride out the dry spell in order for a larger hit to happen.

Low-volatility games do the opposite. Their returns are spread more evenly through smaller, more regular payouts. You might not see the huge headline wins but crucially, you won’t blow through your bankroll so quickly.

Progressive Jackpots

Almost all progressive jackpots allocate part of their RTP towards a jackpot prize. Essentially, a small portion of your stake goes to the prize pot on every spin. The key is that this prize will only be won extremely rarely.

The headline RTP can therefore appear generous, but somehow the base game feels considerably less rewarding. 

RTP Isn't a Safety Rating

One of the most worrying pitfalls, in my opinion, is just how many players assume that a high RTP makes a game ‘safe’. Last fiscal year, slots alone generated £4.2 billion in gross gambling yield (casino games in total only generated £5 billion) [1].

All slots have an edge built in - even those with a high RTP. That means you can still lose - and quickly - on a game with a 98% RTP.

In the UK, we’re lucky to have strong regulation surrounding all aspects of casino gaming. At the moment, the cap on online slots stakes is £5 per spin for those aged 25 and over, and £2 for players aged 18 to 24 [2].

Combining this cap with deposit limits, reality checks, time management tools, and understanding your own personal budget is important. It’s important regardless of the RTP displayed in the game lobby. That RTP is a long-term mathematical description of a game, not a prediction of how your slot session will play out.
