Birthday Betting: 10% of Young Dutch Adults Open Accounts on 18th Birthday

Turning eighteen is a major milestone in the Netherlands, and for many, it marks the legal beginning of a gambling habit that often started in the shadows. A series of comprehensive studies by the Dutch Gaming Authority (KSA) has illuminated how gambling has become a socially normalized pastime long before the legal age is reached. Initial contact frequently occurs between the ages of 8 and 12, often through seemingly harmless family activities like Christmas scratchcards or casual bets at home. By the time they reach adulthood, many are ready to jump in immediately.

The data from the KSA’s control database, which analyzed registrations between May 1 and May 7, 2025, revealed 15,761 newly funded accounts. Young adults aged 18 to 24 accounted for 33% of these new registrations. Most strikingly, 41% of these accounts were opened by individuals who had just turned 18. This "birthday effect" suggests that for many, creating a gambling account is a priority as soon as they reach the legal age limit.

Numbers and facts

The statistics for 2024 and 2025 show that 11% of accounts opened by 18-year-olds were registered precisely on their birthday. Within a month of turning 18, that figure rises to 38%. Contrary to the common belief that sports betting is the primary gateway, 72% of young adult accounts started with casino games. Only 11% began exclusively with sports betting. These young players gamble an average of four days per month in their first quarter, with a median daily stake of €111, which is notably lower than the €209 averaged by older adults.

Minors also frequently circumvent age restrictions by sharing accounts belonging to older friends or relatives. The study conducted by Youngworks found that mobile payment apps like Tikkie are used to pool and transfer money for gambling purposes. Popular platforms among this demographic include TOTO, Bet365, BetCity, and Unibet. The exposure to advertising on TikTok and during sports broadcasts remains a significant factor in the normalisation of gambling behavior among those under 18.

Background

In response to these findings, Meryam Sümer of the CDA party has called for the minimum age for online gambling to be raised from 18 to 24. This proposal stems from reports that one in five young people in Enschede is in debt. However, the KSA chairman has cautioned against such a drastic move, arguing that it would simply push young people toward the illegal market where no player protections exist. In a blog post from February 2025, he noted that minors are already accessing illegal sites with a few clicks.

"I find it particularly concerning that more and more people, and especially young people, have started gambling online and are getting into trouble as a result. It is high time to reverse this trend." - Van Bruggen, Cabinet Member

The Dutch government proposed a near-total ban on online gambling advertising in June 2026. While most students in the MBO system gamble infrequently, approximately 2% show signs of gambling-related harm. This risk is particularly high for those involved in multi-product gambling and online platforms. The social environment, where poker games and football pools are common, continues to foster a strong sense of normalcy around these high-risk activities.

Why it matters for German players

For German players, the Dutch situation serves as a stark reminder of why the State Treaty on Gambling (GlüStV 2021) is so rigid. In Germany, the protection of young adults is a top priority, enforced through the LUGAS and OASIS systems. While Dutch politicians debate raising the age to 24, Germany relies on strict deposit limits of €1,000 per month and a €1 stake limit per spin on slots to mitigate the risk of debt. These measures ensure that the "birthday effect" does not lead to immediate financial ruin for new players.

What it means for GGL-licensed casinos

Casinos licensed by the GGL must maintain the highest standards of age verification and social responsibility. The Dutch report highlights that young players often try to use third-party accounts or payment methods. German operators must ensure their KYC processes are foolproof to prevent similar circumvention. By strictly adhering to GGL regulations, German casinos can demonstrate that a well-regulated legal market is the best defense against gambling harm, potentially preventing even harsher regulatory crackdowns like those currently proposed in the Netherlands.
