When it comes to playing slots, many gamblers are interested in maximizing their chances of winning and finding profitable non GamStop casino games. There are two important factors to consider in this search: the return to player ratio and volatility, especially when looking for secure UK non-GamStop casino experiences that combine reliability with exciting gameplay.
In this article, we will reveal the secrets of choosing the most profitable slot machines: discover what RTP and volatility are, as well as give tips on choosing the best slots to play at the casino outside GamStop.
What is RTP?
The return to the player, RTP, is the percentage of winning bets from the total amount of bets in the slot machine. The indicator is used both in offline and online casinos.
The RTP is set by the official provider during the development of a specific slot and cannot be adjusted after launch. The verification of compliance with the declared RTP is carried out by third-party auditing companies, the most famous of which are eCOGRA, iTech Labs, Gaming Laboratories International (GLI) and Technical Systems Testing (TST). If the stated and actual figures do not match, the slot simply will not receive confirmation and will not be released. You can easily find out the RTP slot in the information section (sometimes even in the demo version).
How to Calculate RTP?
Calculating RTP on your own is pointless, since this indicator is affected by data that is not available to players.:
- The total number of all bets.
- Bonus drop rate.
- The maximum winning amount of all bets.
- The volatility of the slot is the frequency of winnings.
- The high volatility of the slot means winnings for smaller amounts, but more often.
By the way, RTP does not include bonuses or other methods of attracting customers to the casino.
Slots with high RTP
If you want to use RTP data in your gambling experience, then you need to know which slots are suitable. As of December 2025, the following slots on the not on GamStop platforms have the highest RTP:
- Ryse of the Mighty Gods by OneTouch — 99.1%
- Book of 99 from Relax Gaming — 99%
- Mega Joker from NetEnt — 99%
- Jackpot 6000 from NetEnt — 98.9%
- Gold Digger: Mines from iSoftBet — 98.88%
- Ugga Bugga from Multi-Spin Slot Playtech — 98.74%
- Chess Mate from MultiSlot — 98.72%
Keep in mind that RTP shows the attractiveness of the slot for the player from the first place, depending on what he wants to get: a payout here and now, a big jackpot in the distance or accumulate jackpots and not get anything at the moment.
What is Slot Volatility?
Volatility is an indicator of the risk of playing slots: how often and in what amounts the machine will give out winnings. Let’s compare the slots with high and low volatility.
Volatility comes in three types:
- Low. These slot machines are ideal for beginners and amateurs alike. You will often win, but little by little. Some payouts won’t even cover the cost of the spin. Low-volatility slots are used to attract new users to the outside GamStop casino. They allow you to stretch one deposit for a long time. In this case, the client will often even leave with a small profit.
- Average. The most popular slots today because they have balanced odds of winning and the size of the winnings. It’s not worth waiting for big jackpots, but average payouts happen regularly.
- High. It’s really possible to hit the jackpot on this machine. Prizes rarely fall out, so they are not suitable for regular gaming: the risk of losing all the money you came to the casino off GamStop with is too high.
Highly volatile slot:
- Usually “go silent” for dozens of spins.
- Can issue x500+ suddenly.
- It requires patience, bankroll, and nerves.
- Suitable for: drifts, outside GamStop casino bonus hunting, tournaments.
Low-volatility slot:
- Usually gives small winnings (x2-x10).
- Almost does not “eat up” the balance dramatically.
- Does not give out large winnings.
- Suitable for: long sessions, bonus training, beginners of the non GamStop casinos.
Important: Volatility does not affect RTP. Two games can have the same RTP (for example, 96%), but they behave completely differently in the session.
What is a Slot Variance?
Variance is often confused with volatility, but these are different indicators. The variance shows the degree of deviation from the RTP, that is, the difference between expectations and reality. That is, the deviation shows the true degree of recoil of the machine at a certain moment.
The level of deviation, that is, fluctuations, is not indicated anywhere, and it is impossible to reliably determine it.
The Importance of Considering RTP and Volatility When Choosing Slots at the Casino not on GamStop
When choosing machines at the not on GamStop site, it is crucial to consider both the return to the player and the volatility. RTP provides insight into the long-term payout potential of the game, allowing gamers to maximize their chances of winning. The level of risk determines the balance of lose and reward, satisfying the different preferences of the players. A careful assessment of both factors allows you to make informed choices, improving the overall gaming experience and increasing the chances of getting decent winnings.
