Online gaming has evolved dramatically in recent years, offering players a wide variety of slot machines and games with the potential for significant returns. However, not all online iGames and eGames are created equal when it comes to reliability and payout rates. One of the most critical factors affecting your chances of winning is the license under which the casino operates. Some licenses are more reputable than others, providing higher transparency, certified games, and better average return-to-player (RTP) percentages. This is particularly relevant when exploring alternatives like non-GamStop Casinos by 1337, which often operate under different licensing frameworks and appeal to players seeking more flexibility. In this article, we’ll explore the most reliable casino licenses associated with high-payout games, what makes them trustworthy, and how players can use this information to their advantage.

Why Licensing Matters
Online iGaming licenses are regulatory approvals granted by national or regional gaming authorities. They establish the legal framework under which iGaming must operate. A trustworthy license ensures not only that the iGaming is operating within the law but also that it adheres to strict standards regarding fairness, financial transparency, and player protection.
Licenses also determine the types of games that can be offered and the rules surrounding their RTP — the percentage of wagered money a slot machine or game is expected to pay back to players over time. The higher the RTP, the better the odds for the player.
The Most Trusted Licenses for High Payouts
Let’s take a closer look at the most respected online gaming licenses and what makes them ideal for players seeking high-payout opportunities.
1. MGA – Malta Gaming Authority
Region: European Union
Why it matters: The MGA is known for its rigorous requirements and transparency standards. Casinos under the MGA license must offer certified games with clear RTP disclosures.
High-RTP Examples:
- Playtech slots – RTP of up to 97.06%
- NetEnt slots – RTP ranges between 96% and 98%
Certification: Games are independently verified by organisations like eCOGRA and iTech Labs, ensuring fair play and reliability.
2. UKGC – United Kingdom Gambling Commission
Region: United Kingdom
Why it matters: The UKGC enforces some of the strictest regulations in the online gambling world. It requires complete transparency about payout rates and mandates regular audits.
High-RTP Examples:
- Pragmatic Play slots – RTPs typically above 97%
- Megaways games – Known for their generous volatility and RTPs
Certification: Regularly audited by GLI and BMM Testlabs, guaranteeing unbiased results.
3. ADM/AAMS – Agenzia delle Dogane e dei Monopoli (Italy)
Region: Italy
Why it matters: This license is extremely player-focused, requiring that RTPs are clearly indicated in each game’s rules.
High-RTP Examples:
- Book of 99 – Exceptional RTP of 99%
- 1429 Uncharted Sea – RTP of 98.60%
- Vinci la Gallina – RTP of 97.61%
Certification: All games are verified by independent Italian-approved testing agencies.
4. Curaçao eGaming
Region: Caribbean
Why it matters: While more flexible in terms of regulation, this license is popular among eGaming that host progressive jackpots.
High-RTP Examples:
- Mega Fortune – RTP of 96% and record-breaking jackpots
- Hall of Gods – Another popular jackpot game with solid RTP
Certification: Subject to audits by international third-party firms.
5. GRA – Gibraltar Regulatory Authority
Region: Gibraltar
Why it matters: Offers strong privacy protection and verified game integrity.
High-RTP Examples: Slots often range between 95% and 97% RTP.
Certification: Casinos are subject to periodic reviews and game audits.
Key Factors Influencing Payout Potential
Several factors go beyond licensing when considering which games offer the highest return:
● Certified RTP
Licenses like those from MGA and ADM not only require RTP to be public but also demand that the figures be certified. For example, an MGA-licensed casino such as LeoVegas might offer games like Mega Fortune with a certified RTP of 96%, providing players with transparent data on expected returns.
● Progressive Jackpots
Progressive jackpots can transform modest bets into life-changing wins. Games such as Mega Fortune — which paid out a €16.7 million prize under an MGA license — and Hall of Gods are prime examples of high-risk, high-reward games often found on platforms with Curaçao or Malta licenses.
● Transparent RNG Audits
RNG (Random Number Generator) systems ensure that every game result is fair and unpredictable. The UKGC, for instance, requires quarterly RNG audits to be conducted by recognised bodies like BMM or GLI. This level of oversight guarantees that players aren’t at a disadvantage due to flawed or biased algorithms.
The Most Profitable Slots: A Quick Ranking
Here’s a quick overview of some of the most lucrative slots based on their RTP and the licenses under which they operate:
Slot Title | RTP | Licensing Authority | Recommended Casino |
Book of 99 | 99% | ADM (Italy) | SNAI |

Note: Licensing doesn’t directly influence RTP, but it ensures games are verified by independent auditors, offering players a fair shot at real winnings.
Final Thoughts
When choosing where to gamble online, don’t just focus on flashy bonuses or the number of available games. The license under which a casino operates can be the difference between a fair gaming experience and one riddled with risks. Opting for online casinos with licenses from MGA, UKGC, or ADM means you’re playing under strict oversight, enjoying games with high RTPs, and betting on transparency.
To maximise your potential payouts, always:
- Prioritise games with RTPs over 97%
- Look for casinos that host certified progressive jackpots
- Choose platforms regulated by reputable licensing bodies
By doing so, you’re not just playing — you’re playing smart.
