KVA expressed concern over the potential manipulation of Google’s autocomplete function by unauthorised operators and websites primarily set up to redirect Dutch consumers to illegal gambling offers.

Many players use a fixed cash-out target, such as 1.5x or 2x, and exit automatically every round. This removes emotion from the decision and keeps losses predictable.

The report utilised various methods to estimate the size and scale of Europe’s black market, including web traffic, digital marketing, macros data and regulations in place across the 28 markets surveyed.

This data was cross referenced with SimilarWeb traffic analysis to confirm the scale of activity. In some markets, the number of illegal sites being actively marketed was much higher than those that have local licences to operate.
