Poland's Consumer Watchdog Is Using AI to Hunt Dark Patterns in Betting Apps

UOKiK is examining seven bookmakers for interface design that manipulates behaviour, with a tool built specifically to spot it. Five of them face separate proceedings where the exposure is 10% of annual turnover.

• Poland's Office of Competition and Consumer Protection, UOKiK, is assessing seven licensed bookmakers for so-called dark patterns: interface, messaging and process design that can manipulate consumer decisions
• The companies named are STS, Fortuna Online Zaklady Bukmacherskie, Superbet Zaklady Bukmacherskie, Bukmacherska (fuksiarz.pl), eToto Zaklady Bukmacherskie, LV Bet Zaklady Bukmacherskie and Totalbet Zaklady Bukmacherskie
• The review covers websites, mobile apps and the information put in front of users, and UOKiK says its analysis is assisted by an artificial intelligence tool built specifically to recognise these practices
• It is examining whether operators push users toward more frequent play and whether they make it harder for a customer to cut themselves off from gambling
• Separately, UOKiK has opened proceedings against five of them, STS, Fortuna Online, Superbet, Bukmacherska and eToto, over allegedly prohibited contractual clauses, where the penalty can reach 10% of annual turnover

The Authority Doing This Is Not the Gambling Regulator

Poland licenses and taxes gambling through the Ministry of Finance, in a market where experts have been arguing the online monopoly should end. UOKiK is something else: the competition and consumer protection authority, with a remit over unfair commercial practices and abusive contract terms across the whole economy.

That is the significant fact about this action. The questions being asked are safer-gambling questions, whether an operator nudges a customer toward playing more often, and whether it makes self-exclusion harder than it should be. But they are being asked under consumer law, by a body whose penalties are calculated in competition-law terms.

The review covers seven licensed bookmakers: STS, Fortuna Online Zaklady Bukmacherskie, Superbet Zaklady Bukmacherskie, Bukmacherska, which trades as fuksiarz.pl, eToto Zaklady Bukmacherskie, LV Bet Zaklady Bukmacherskie and Totalbet Zaklady Bukmacherskie. It looks at websites, mobile applications and the messages presented to users, including the terms a customer agrees to when opening an account. Trade reporting indicates these are routine checks rather than a response to specific complaints.

Running alongside, and considerably more serious, UOKiK has opened proceedings against five of the seven, STS, Fortuna Online, Superbet, Bukmacherska and eToto, concerning allegedly prohibited contractual provisions. Where such clauses are established, Polish law allows a penalty of up to 10% of annual turnover. LV Bet and Totalbet are named in the review but not in those proceedings.

The detail that separates this from a routine compliance sweep is the method. UOKiK says its analysis is supported by an artificial intelligence tool designed specifically to identify dark patterns across interfaces at scale.

A Regulator That Can Read Every Screen Changes the Compliance Problem

Dark patterns have been difficult to police for a practical reason rather than a legal one. They are not a clause in a document; they are a countdown timer, a pre-ticked box, a confirmation step that is one tap for depositing and four for a limit. Proving a pattern historically meant a human working through an app screen by screen, which does not scale past a handful of operators. A tool built to recognise those constructions changes the economics of enforcement, and it changes them for the regulator, not the operator. Compliance teams that have relied on nobody having time to look at the fourteenth screen of an onboarding flow should assume somebody now does.

Self-Exclusion Friction Is Being Prosecuted as a Consumer Harm

The most consequential line in what UOKiK has described is whether operators make it harder for users to cut themselves off. In most European markets that is a licensing matter, handled by the gambling regulator, with licensing consequences: Malta's regulator, for instance, used mystery shopping to expose cross-brand self-exclusion gaps. Framing it as an unfair commercial practice moves it into a body of law with a different burden, a different enforcement culture and much larger fines. It also makes it portable. An argument that a difficult self-exclusion journey is a manipulative design choice does not depend on any provision of gambling law, which means it travels to any market with a consumer authority willing to make it.

Ten Per Cent of Turnover Is a Different Order of Penalty

Gambling regulators typically fine in the low millions, sized against the failing. Competition and consumer authorities size penalties against the company. Up to 10% of annual turnover, the exposure facing the five firms in the contractual-clause proceedings, is the scale European regulators reserve for cartel conduct. Whether UOKiK goes anywhere near the ceiling is a separate question and it usually does not. But an operator assessing risk in Poland now has to model two regulators with different instruments, and the one without gambling in its name has the heavier one. That is a live consideration across a bloc where Brussels is already eyeing an 11 billion euro annual levy on online gambling.

Poland's gambling regulator did not open this. That is the point worth carrying into every other market with a consumer authority and a betting app.
