European Slot Rankings Reveal Differences in Search Interest

European slot rankings show substantial differences in how search interest spreads across individual online slots. A September 22, 2026 snapshot places Double Bubble far ahead of its UK competitors, while Spain’s leading titles each account for a much smaller share of tracked interest.

The comparison covers six countries and ranks games using Blask’s Share of Interest, or SoI. Pirots 4 takes first place in Spain and the Netherlands, and also leads Sweden. Other markets have different leaders, with Book of Ra heading Germany’s ranking and Gates of Olympus taking the top position in Italy.

The figures describe relative search attention. They do not establish which games customers play most frequently or which titles generate the highest betting volume.

Search Data Defines the Rankings

Blask builds its game-interest measurements by identifying titles and connecting them with relevant search terms. Its process includes detecting unfamiliar game logos on operator websites, then checking game names against published material. A content editor reviews the country-specific keyword assigned to each title.

The platform gathers search-volume data for those keywords and normalizes the figures against a rolling 12-month baseline. This produces a Blask Index that expresses relative interest rather than raw search totals.

To calculate Share of Interest, Blask divides a game’s index by the combined index for tracked games in the relevant market. The resulting percentage shows that title’s share of measured attention.

For example, a game with an index of 800 against a combined total of 10,000 would hold an 8% share. Changes in those underlying index values can alter a game’s share over time.

The European comparison includes only titles classified as slots. Coverage also differs between countries: Germany has 250 tracked brands, while the UK has 236. Sweden has 150, Spain has 83, and the Netherlands has 82. Italy has the smallest tracked group at 79.

National Leaders Hold Unequal Shares

Double Bubble accounts for 55.9% SoI in the UK, giving it a considerable lead over Big Bass Splash at 4.8%. Bigger Bass Splash follows at 4.7%. Sugar Rush records 4.4%, while Big Bass Bonanza reaches 3.9%.

Germany’s ranking gives Book of Ra an 18.1% share. Pirots follows with 13.2%, and Razor Shark records 6.2%.

Italy has a closer contest at the top. Gates of Olympus holds 7.6%, with Sweet Bonanza at 6.9%. Starburst records 5.6%. Pragmatic Play supplies six of Italy’s top-10 titles, which together account for 30.1% SoI.

Spain shows the most dispersed ranking. Pirots 4 ranks first, although both it and Sweet Bonanza round to 3.4%. Gates of Olympus and Golden Bull each reach 2.7%.

Pirots 4 leads the Netherlands with 6.1%. Sweet Bonanza follows at 3.8%, narrowly ahead of Le Pharaoh at 3.7%.

In Sweden, Pirots 4 records 12.9%, followed by Starburst at 8.7%. Bonanza reaches 7.9%. Pirots 4 and Pirots 3 jointly account for 20.5% of measured slot interest there.

Shared Titles Appear Across Several Markets

Gates of Olympus and Sweet Bonanza have the broadest top-10 presence, appearing in five countries each. Big Bass Bonanza appears in four, as do Book of Dead and Sugar Rush.

Pirots 4 reaches the top 10 in three markets and leads each of them. No individual game appears in all six national top-10 lists.

Spain and the Netherlands share eight top-10 titles. Germany has six titles that do not appear in the other countries’ rankings, while the UK has five.

Across the combined lists, Pragmatic Play occupies 24 of the 60 available positions, representing 40%. At least one of its games appears in every country covered.

These results show both recurring European titles and substantial national differences. The snapshot captures their relative search positions on a particular date; continuing changes in interest can reshape subsequent rankings.
