• The UK’s Advertising Standards Authority (ASA) has ruled against supplier Play’n GO for ad placements that breached rules on protecting minors from gambling promotion.
• The ruling, published 16th July, found three banner adverts featuring a superhero bunny, anime princesses, and a robot DJ had a strong appeal to under-18s.
• The ASA concluded that the programmatic ad-serving method used was not robust enough to prevent the content from appearing alongside media consumed by children.
• While no financial penalty was issued, the ads must not appear again in their current form, highlighting a growing regulatory intolerance for cartoon-style imagery in gambling marketing.
• The decision underscores the increasing pressure on both B2B suppliers and operators to ensure their advertising is not only creatively compliant but also technically failsafe in its targeting.

ASA Rules Content and Targeting Fell Short

In a significant ruling for the B2B sector, the UK’s Advertising Standards Authority (ASA) has formally sanctioned prominent game supplier Play’n GO. The decision found that three of the company’s online banner adverts breached the UK’s advertising code by using imagery likely to have a strong appeal to children and young persons.

The adverts in question, seen in April, promoted several of the supplier’s well-known slot titles and featured a cartoon superhero Easter bunny, three anime-style princesses, and a robot DJ. The investigation was launched after complainants reported seeing the ads displayed adjacent to their children’s email inboxes.

The ASA upheld the complaints, citing breaches of CAP Code rules 16.1 and 16.3.12, which are designed to prevent gambling advertising from appealing to or being targeted at under-18s. The regulator stated that despite the inclusion of 18+ markers and responsible gambling logos, the use of such characters is considered high-risk. It concluded that Play’n GO had “not excluded under-18s from the audience with the highest level of accuracy required” for such content.

Programmatic Advertising Under Scrutiny

In its defence, Play’n GO argued that the characters were designed for an adult audience and that the gameplay of the associated titles requires an “adult mindset.” The company explained that the ads were served programmatically via the platform Adroll, using a combination of cookie-based retargeting for previous website visitors and “lookalike” modelling.

However, the ASA dismissed this approach as insufficiently robust. The regulator highlighted that relying on self-declared age and behavioural data cannot guarantee the exclusion of minors, particularly on shared devices. It stated that for creative with such a high risk of youth appeal, it would expect targeting to be based on more definitive age-verification methods, such as marketing lists validated by payment data or credit checks, to ensure the audience is exclusively adult.

A Warning Shot for Suppliers and Operators

This ruling serves as a critical reminder for the entire supply chain, from game designers to operators and affiliate partners. The ASA’s focus was not just on the creative content itself, but on the failure of the delivery mechanism to safeguard against underage exposure. The decision reinforces a clear message: the responsibility for compliant advertising does not end with the operator.

The sanction against a major B2B supplier like Play’n GO signals that the UK’s regulatory bodies are taking an increasingly holistic view of the ecosystem. It comes amid a broader tightening of advertising standards across Europe and as the industry awaits the full implementation of the UK’s Gambling White Paper reforms. For content-rich suppliers with strong IP, this ruling necessitates a rigorous review of both creative assets and the marketing partnerships used to promote them, ensuring that regulatory compliance is maintained as a core business principle.
