The Swedish gambling regulator, Spelinspektionen, has fined Videoslots SEK12m (£937,016) for failing to help customers better manage their gambling behaviour when it had reason to do so.

The regulator said that the company did not take sufficiently effective measures to intervene on excessive gaming and “did not act promptly enough.”

The fine, along with a formal warning, comes after a Spelinspektionen investigation into Videoslots’ customer activity in spring last year. The regulator found that the company breached its duty of care obligations.

Twelve customers’ gaming behaviour was analysed, with the regulator concluding that their gambling patterns, deposit behaviours and “significant losses” were among the “multiple indicators” that the customers engaged in excessive gaming.

A number of the 12 customers returned to Videoslots’ platform to play “multiple times” during the day or play “continuously for many hours.”

The regulator said all of the customers had “very high deposit limits.” Three had limits of SEK1m (£78,164), one had a limit of SEK4.5m (£351,912) and another player’s limit was SEK300m (£23.5m).

All customers deposited “large amounts” during the review period, Spelinspektionen said, including one who deposited SEK1.8m (£140,785) and another who deposited SEK1.3m (£101,721).

“Several customers exhibited a deposit pattern where withdrawn amounts were deposited again shortly after being withdrawn,” the regulator said.

“For several customers, there were also a large number of deposits in a short period. Some customers regularly made multiple deposits per gambling day… and one customer had days with up to 28 deposits.”

“In light of the above, Spelinspektionen assesses that all the customers have engaged in excessive gambling during the review period,” the regulator concluded.

“The company has pointed out that individual indicators, on their own, may not necessarily be signs of excessive gambling. According to Spelinspektionen, all the above-mentioned indicators are signs of excessive gambling, and the overall assessment of all indicators forms the basis for the conclusion.”
