This analysis reviews European gaming data from October 2024 to October 2025, based on an average of 6.2 million active players per month. The report covers four key markets: Spain, Greece, Italy and the UK. It tracks five key indicators: monthly deposit amount, sports betting amount, casino betting amount, player activity days and customer retention rate.

Key findings and insights

• The engagement king: Greek players settle as the most engaged, high-value, loyal, and active of all, primarily focused on sports betting.
• The casino lovers: While Greek players lead in almost every indicator, Spanish players are the biggest casino spenders, leading with an average monthly casino bet amount of $2,688, just ahead of Greece ($2,569). Spanish players may deposit less but place larger wagers, particularly on casino games.
• Casino growth: While sports betting faces much more volatility over the year, especially during summer and off-season, casino betting shows much more stability, with a slight growth trend.
• Ascending trend: All four countries saw an increase in several indicators from September to October 2025, reaching the same level or even surpassing the figures from October 2024, which indicates a growth trend in the sector, despite occasional volatilities.
