In today’s topic, we take a look at RTP in gambling. More specifically, what does RTP stand for, how it affects slots and what the percentage means? Let’s take a look.


RTP stands for Return to Player. And, the concept of it is also quite easy to grasp.

When playing a slot game with a 95% RTP, here’s basically what it means. Say, you play with €100 and place €1 every spin. After 100 spins, the RTP suggests that you will end up with €95. This is the Return to Player value for the specific slot. Thus, this also explains what you’re set to lose when playing the game.

Mind you, it’s important to keep in mind that this figure is after thousands, if not millions, of spins. If you were to actually spin 100 times with €1, anything can happen. The RTP is just an average taken over the course of a long period of time.

Statistical Approach Based on Slots

In a nutshell, RTP in gambling can be calculated by ‘Total Amount Won’ / (divided) by ‘Total Amount Wagered’. This is the case in slot machines. That’s why you’ll see that the best jackpot slot machines are the ones with the highest percentage.

Note that this simple equation is not just a randomly generated number. Instead, it is the actual value of the slot game played by real people with real money.

RTP Value in Table Games

When calculating RTP in gambling table games, the theory is a little different. First of all, the RTP is referred to as the House Advantage. This is similar to when entering any type of casino – land-based or online.

Thus, the RTP for roulette, craps or Casino War, is different from slots. The ratio can be calculated for RTP as 100% – (minus) House Edge. Thus, by knowing the House Edge, you’ll be able to calculate the RTP for specific table games too.

For instance

If we say that roulette has a House Advantage of 5%, that would make the RTP 95%. The 5% House Advantage can come from roulette not requiring any skills or certain strategy. Another factor could be the zero on the table, which is neither even, odd, red or black.

RTP in the Lottery

If you thought that the lottery doesn’t require any RTP, you’re mistaken. Similar to slots, the RTP would be the Total Amount Won / Total Amount Wagered.

So, let’s say there are 1,000,000 lottery tickets. If a ticket costs $1, then that’s $1,000,000 for the state-run lottery. However, there would have to be winners. So, if there’s $900,000 won, either by 900,000 players at $1 each or 9 players winning $100,000, the lottery still makes $100,000.

That makes the RTP of the lottery 90%. There are two different alternatives. 900,000 players win $1 or 9 players win $100,000. This would depend on if there is a high hit frequency with low prizes or visa-versa.

Facts about RTP in Gambling

Many players believe that the RTP of slots can be manipulated to deceive gamers. However, that is completely false.

The RTP percentage is set by software providers, thus, casinos cannot exploit these values.

Another false belief is that the RTP will decide if you’ll win or not. I mean think about it for a minute. You could win big on a slot with an RTP of 88% but then not get squat for a slot with an RTP of 99%. It truly depends on your luck. However, RTP slots with higher percentages do play better than others.
