Oh, the RTP debate, it never goes old! Perhaps everyone already knows about RTP, but did you know that high RTP is not always good and can change over time? Let's dig it!
First and foremost:
RTP and Volatility
* RTP: it is like a fee for slots operator, in the long run, let's say for $1 bet, the operator will earn $0.05 and $0.95 will be put in the pot. Rule of thumb: search for slots that have more than 95% RTP.
* Volatility: it is like a risk for slots game. In low volatility slots, action will occur more often, but it pays lower than high volatility slots.
Theoretical RTP for extremely high volatility slotsLet's see how slots that can give 100,000x can get you busted most of the time, even with the 100% Theoretical RTP. Let's say the dev programmed the game to provide 0x (zero) payouts in 99,999/100,000 spins and 100,000x payout in 1/100,000 spins. In theory, they can label their slot game to have 100% Theoretical RTP. In reality, players will get busted with a probability of 99.999%. It might be okay if they really pay if some "holy" dude gets the 100,000x, but we have read about this slot malfunction and whatever else that deny their obligation to pay.
Therefore, if you see high volatility slots that have high RTP, you should ask:
- How big is the max win? 1,000x, 10,000x, or 100,000x?
- What's the volatility and the hit frequency?
- Even if I (somehow) win big, what's the probability for me getting paid 100%? Will my KYC be denied?
Live RTP will fluctuate based on the volatility (variance) and how many spins performed. Just ignore this since the data from one casino cannot represent data from all casinos (population). Perhaps at Casino A, the live RTP for Slot A is 150%. It doesn't mean that the next player will get rekt because maybe, on average, the live RTP (population) is 80%, so there is plenty room to bounce back (or more wins).
Theoretical RTP and Paylines
How about RTP in games that allow users to customize the paylines where they can bet on 1 of 10 pay lines up to 10 of 10 (max) paylines? Well, usually more paylines equal to more RTP, hence the theoretical RTP label is for max paylines. So, better bet on max lines even if it's more expensive if you don't use it as a strategy (to do progressive betting). If you don't trust me, kindly dwell into various slots' information sections, and sometimes you will read "The RTP only applicable for max lines" sort of thing.
RTP Variants: Same Game, Different RTPsAlways check for RTP! That should be the mantra for every slots player who doesn't want to get "soft-scammed" since the exact same game can use different RTP settings.
The provider who are known to have different RTP settings, as follows:
- Play'n Go:
someone even reported to have only 84% RTP;
- Pragmatic Play: there are three RTP choices from 94% to 96%;
- Red Tiger: multiple RTPs down to 92%;
source- Nolimit City: usually the DX version pays -2% from the standard version (from my observation only, citation needed).

gambling is for adults who understand the risks involved with this game. Plus, OP wouldn't take responsibility whatsoever if you then become slots addict and lose lots of money after reading this thread.More information visit:

. I also won a bunch of times in a random slot game when the live RTP was sitting at 105%.
