Over 60% Drop in Active Accounts on B+ Platforms in Belgium by 2025

Online platforms operating under the additional B+ licence in Belgium lost 340,443 active accounts between 2024 and 2025, a drop of 60.49%, according to the 2025 annual report cited by Gambling Club. Despite the significant contraction in active accounts, the gross gaming revenue (GGR) of the B+ segment only decreased by 13.66% to €165.75 million in 2025, and the average GGR per account doubled to €745.

I write as Emilio Navarro, technology correspondent for the sector. This article breaks down the figures, the regulatory context, and the implications for operators and regulators in the Belgian market.

What is an online gaming hall and how is it regulated in Belgium?

An online gaming hall in Belgium operates with a B+-licence. This additional licence can only be obtained by a company that is tied to a physical slot machine hall with a B-licence. The B+ segment is legally distinct from online casinos that depend on an A+-licence: A+ casinos typically offer table games and live gaming; B+ platforms focus on automatic games permitted by that licence category.

Operators and the public can verify the licence type in the official registry of the Kansspelcommissie. Gambling Club also maintains an explanatory inventory of legal casinos in Belgium and the distinction between A+ and B+.

Decline of active accounts: concrete figures and how they are counted.

In 2025, B+ platforms registered 222,394 active accounts, down from 562,837 in 2024. The difference of 340,443 accounts represents a reduction of 60.49%. The definition used for 'active' is simple: an account that was used at least once during the year. An inactive account in 2025 is not necessarily deleted; it simply no longer counts as active.

The data counts accounts, not individuals: a person may have multiple accounts with different licensed operators. Therefore, the drop in active accounts does not directly equate to 340,443 Belgian players who have stopped playing.

Revenue, bets, and average value per account (focus keyword: average GGR per account).

The total GGR of the B+ segment fell from €191.97 million in 2024 to €165.75 million in 2025, a loss of €26.22 million or 13.66%. However, the total amount wagered on these platforms only decreased from €5.38 billion to €5.18 billion, a decline of 3.64%.

The contrast explains why the average GGR per account rose sharply: in 2024, the average GGR per active account was €341, and in 2025 it reached €745, an increase of 118.52%. The practical consequence is that accounts that remain active are now, on average, more than double as valuable to the sector.

This jump may be due to the exit of casual players while a smaller but more intense user base continued to wager. Averages do not reveal individual distribution: a minority with high stakes can elevate the mean.

Comparison with other segments and possible reallocations of activity.

While the B+ segment declined, the entire Belgian online market grew 5.41% to a GGR of €964.46 million in 2025. Casinos with A+-licences were the ones driving the growth: their online GGR rose 12.99%, from €490.42 million to €554.11 million, and active A+ accounts increased from 342,844 to 458,403 (growth of 33.71%).

The two subsectors moved in opposite directions: B+ lost more than half of its active accounts, A+ gained more than 115,000. It is plausible that some regulated activity has shifted to A+ platforms; however, the data do not prove a direct transfer of accounts, as some operators manage multiple licences and can redistribute products, accounts, or reports between platforms.

Historical trend, regulatory changes, and legal context.

The decline of the B+ segment began before 2025. In 2023, the online GGR of the segment was €252.01 million, in 2024 it fell to €191.97 million and in 2025 it continued to €165.75 million. In two years, the accumulated loss exceeds €86 million, placing the segment approximately 34% below 2023 levels.

Relevant regulatory factors: since July 2023, Belgium implemented a broad ban on gambling advertising, and has restricted bonuses and other financial incentives. The minimum age for certain games increased in September 2024, although B+ platforms already required a minimum age of 21 years, so this increase does not fully explain the specific decline in B+.

Status of the physical market and B/B+ operational fabric.

The business of physical slot machine halls showed less volatility: their total GGR fell by 4.17%, from €192.79 million in 2024 to €184.74 million in 2025. Visits in 2025 were 4.61 million, just 0.27% less than the previous year; unique visitors fell 3.56% to 470,766.

At the end of 2025, there were 175 B-licences active for physical locations and 48 additional B+-licences for online activities. During 2025, five new B+-licences were granted, one was renewed, six operators voluntarily surrendered their B+-licence, and twelve changes of internet address were approved. These movements suggest that the physical fabric remained relatively stable while the online B+ component was the most affected.

Risks, compliance, and the illegal market.

The report only covers operators within the Belgian licensing regime; it does not include activity on foreign sites without a Belgian licence. There are no public figures in the report that allow quantification of whether the activity lost in B+ migrated to A+ platforms or to illegal offshore operators.

Offshore sites are not necessarily linked to EPIS and may evade controls over limits, gambling behaviour, and payments. Given the combination of fewer accounts and higher GGR per account, player protection for the remaining public in the B+ segment becomes more relevant: deposit limits and monitoring of spending increases must receive enhanced attention.

Gambling Club explains the differences between legal and illegal sites and points out help resources. If gambling begins to take up more money, time, or attention, anonymous information and advice can be requested at De Druglijn.

"The combination of fewer accounts and a much higher average GGR makes player protection a priority for the B+ sector," said Gambling Club in its analysis of the 2025 report.

What does this imply for operators and regulators?

For B+ operators, the practical priority is to understand the composition of the remaining audience and review limit controls and risk escalation detection. For the regulator, the question is whether the measures taken since 2023 affect the acquisition of new players or only the composition of the active pool.

Operators with multiple licences may be shifting activity within the regulatory perimeter; therefore, any interpretation should contemplate the possibility of account reassignment between A+ and B+.
