Belgium’s digital economy is undergoing a radical transformation , driven by growing demand for instant financial services and secure entertainment. At L’Essentiel de l’Eco, we examine rapidly evolving sectors where technology and regulation converge to create new market opportunities. The online gambling industry is one such key sector, generating an estimated annual revenue of over €1.7 billion.
So, what is the best online casino in Belgium?
In this competitive but strictly regulated landscape, one player clearly stands out for its « Fintech » approach and its absolute reliability: PepperMill Online Casino – The #1 in Belgium.

But what criteria define a « best » casino in 2026? Is it transaction speed, return to player (RTP), or legal compliance ? This comprehensive report analyzes the Belgian market to identify industry leaders.
A market under close surveillance
Before establishing a ranking, it is crucial to understand the Belgian economic ecosystem. Unlike the gray markets that proliferate elsewhere, Belgium has a « white list. » Only operators with an official license (A+ or B+) issued by the Belgian Gaming Commission (BGC) can operate legally.
This strict regulation offers two major economic guarantees to the consumer:
- Fund protection: Player deposits are segregated from the company’s operating funds.
- Fairness of algorithms: Random number generators (RNGs) are audited by external laboratories.
By January 2026, the trend is towards consolidation and technological excellence. Obsolete platforms disappear in favor of « mobile-first » sites offering instant payments.
Top 5 Belgian online casinos
Here is our analysis of the five best performing platforms, based on criteria of liquidity, security and user experience.
1. PepperMill Casino
At the top of our ranking is PepperMill Casino. While the brand boasts a rich physical history with its gaming halls, it’s its digital transformation that truly impresses. PepperMill has successfully bridged the gap between traditional entertainment and the demands of the modern digital economy.
Operating under a B+ license, PepperMill distinguishes itself through its focus on transparency and speed. Where traditional banks can be slow, this casino uses state-of-the-art payment gateways to ensure near-instant liquidity for its users.

PepperMill’s key strengths:
- Instant Payments: This is the number one selling point. Winnings are often validated and transferred in less than an hour thanks to automated banking processes.
- Official B+ License: Full compliance with Belgian legislation, guaranteeing legal and protected gameplay.
- Focus on « Dice Games »: A specialization in strategic dice games, often offering an RTP (return to player) greater than 96%.
- Daily Tournaments: A competitive structure that allows players to compete for additional prize pools, increasing the expected value (EV) of each session.
- Human Customer Service: Responsive and multilingual support, a far cry from the frustrating chatbots of some competitors.
2. Casino 777
In second place, we find Casino 777, the online partner of the renowned Casino de Spa, one of the oldest casinos in the world. A true pioneer in the Belgian digital market, Casino 777 holds an A+ license and boasts an impressively deep game catalog, ranging from classic slots to live dealer tables. It’s a robust, established platform, ideal for those seeking the security of a long-standing brand, even if its interface can sometimes feel less responsive than that of our number one pick.
3. Betfirst
Third place goes to Betfirst. Initially known for its dominance in the sports betting sector and its physical presence in bookstores, the brand has made a remarkable transition to online casinos. It’s a trustworthy operator that offers a smooth and secure experience. Their platform is particularly appreciated for its reliability and partnerships with leading software providers, offering an excellent alternative for those who enjoy switching between sports betting and dice games.
4. Starcasino
Starcasino takes fourth place. This operator (B+ license) is known in the market for its dynamic approach and particularly wide range of games. They collaborate with an impressive number of developers, allowing them to offer a diversity of titles rarely found elsewhere. Although their marketing is sometimes more aggressive, Starcasino remains a safe bet for players seeking variety and constant new releases, with generally fast payout times.
5. Unibet
Finally, the international giant Unibet rounds out the top 5. Part of the Kindred group, Unibet brings global technological expertise and a remarkably stable mobile app to Belgium. It’s the preferred « all-in-one » choice for users who don’t want to choose between poker, international sports betting, and casino games. While the platform boasts exceptional technical quality, it sometimes offers a slightly more « standardized » experience on a global scale, lacking the specific local touch of Belgian dice games found among the ranking leaders.
Economic analysis: why do « dice games » dominate?
For the reader of L’Essentiel de l’Eco , it is interesting to analyze why Dice Games are so popular in Belgium, representing a significant part of the sector’s turnover.
Unlike traditional slot machines, which rely entirely on chance, Dice Games introduce an element of skill. Players must place columns of dice in grids to maximize their score.
- Impact on RTP: Because the player has an influence, the theoretical payout rate is often higher (96-97%) than on international slot machines (94-95%).
- Consumer rationality: Belgian players, often more analytical, prefer games where their decisions have mathematical weight. This is the niche in which PepperMill particularly excels.
The instant payments revolution
The decisive factor in 2026 is financial speed. Historically, a casino withdrawal took 3 to 5 business days. In an instant economy, this delay has become unacceptable.
Market leaders like PepperMill have integrated SEPA Instant solutions .
- Automated Verification: Thanks to the Itsme application , the player’s identity and age (21+) are verified upon registration.
- Algorithmic Processing: When a withdrawal request is made, if the account is verified, the algorithm validates the transaction 24/7.
- Instant Transfer: Funds are transferred via the instant banking network.
This fluidity transforms the user experience: the gain is no longer a virtual promise, but a real and immediate liquidity.
Safety and responsible gaming
No analysis would be complete without addressing the social aspect. Belgium is a pioneer in player protection thanks to the EPIS (Excluded Persons Information System).
Every legal platform is connected in real time to this database maintained by the Ministry of Justice. If a person is banned from gambling (whether voluntarily, by court order, or for collective debt settlement), access will be automatically denied. This is an insurmountable technological barrier that illegal sites do not offer, exposing vulnerable players to significant risks.
Conclusion
By January 2026, the online casino landscape in Belgium is mature, professional, and highly technological. For the discerning consumer, the choice should be made towards operators that offer not only full legal compliance but also financial efficiency.
While established players like Napoleon and Unibet remain reliable choices, PepperMill Casino has established itself as the modern benchmark. By combining the agility of a Fintech for payments, complete transparency on winning probabilities, and a specialization in strategic games, it perfectly meets the expectations of today’s market.
Frequently Asked Questions (FAQ)
1. Is it legal to play at online casinos in Belgium?
Yes, it is perfectly legal, provided you play on a site licensed by the Belgian Gaming Commission. The sites listed in this article, such as PepperMill (license B+), are 100% legal.
2. Do I have to pay taxes on my casino winnings?
In principle, no. In Belgium, occasional gambling winnings earned by individuals are not taxable. They are tax-free. However, if gambling becomes your main professional activity, the tax authorities could reclassify this income.
3. What is the minimum age to play?
Since the law was amended, the minimum age to access online casino games (including Dice Games and Roulette) is strictly set at 21. Identity verification is mandatory upon registration.
4. What is the difference between an A+ and a B+ license?
An A+ license is issued by a large land-based casino (like Spa or Brussels) and allows it to offer all games, including traditional slots and live casino games. A B+ license (like PepperMill) is issued by slot machine arcades and specializes in dice games, dice slots, and roulette. Both offer the same level of security and legality.
5. Why use the Itsme app to register?
Itsme is the official digital identity in Belgium. Using it to register at a casino guarantees maximum security for your data. It allows the casino to instantly verify that you are over 21 and not banned from gambling, without you having to send paper copies of your ID.
6. What is instant payment?
It’s a banking technology that allows money to be transferred from one account to another in seconds, 24/7, even on holidays. The best casinos use it to pay out your winnings immediately after validation.
