Poland’s Office of Competition and Consumer Protection (UOKiK) has launched a review of several major bookmakers, examining whether their websites, mobile applications and customer terms comply with consumer protection standards.
The authority said on August 24 that it is conducting explanatory proceedings involving STS, Fortuna Online Zakłady Bukmacherskie, Superbet Zakłady Bukmacherskie, Bukmacherska, which operates Fuksiarz.pl, E-toto Zakłady Bukmacherskie, LV Bet Zakłady Bukmacherskie and Totalbet Zakłady Bukmacherskie.
A central part of the review concerns so-called dark patterns — interface designs, messages or digital processes that can influence users in ways they may not fully recognise. UOKiK is assessing whether betting platforms use mechanisms that could encourage customers to gamble more frequently or make it unnecessarily difficult for them to stop.
The regulator is also examining player protection measures, including how easily users can end or suspend their gambling activity. UOKiK President Tomasz Chróstny said operators in the sector have responsibilities extending beyond basic legal compliance because gambling can affect consumers’ finances, family life and health.
UOKiK has separately been developing artificial intelligence tools designed to identify dark patterns on websites and applications. Earlier in 2026, the authority said its system could analyse page layouts, behavioural design features and source code to help detect potentially manipulative practices.
Alongside the broader market review, UOKiK is pursuing separate proceedings over potentially unlawful contractual clauses used by STS, Fortuna, Superbet, Fuksiarz.pl and E-toto.
The authority is questioning provisions that may give operators excessive discretion over issues such as cancelling bets, blocking customer accounts or determining how winnings are settled. UOKiK said customers should know in advance exactly when an operator can take such measures and what consequences will follow.
Companies found to have used prohibited contractual provisions can face penalties of up to 10% of annual turnover.
The action comes as Poland’s regulated betting sector continues to expand. Recent industry estimates put licensed betting turnover at roughly €4.44 billion in 2025, with online betting accounting for more than 90% of activity.
UOKiK’s review therefore places greater attention on how Poland’s largest betting businesses present their services and manage customer relationships as digital wagering becomes an increasingly dominant part of the market.
