Many casino deposit bonuses also carry specific game exclusions, often targeting high-RTP slots above 96%–97%, which are commonly restricted to prevent bonus abuse.

That is why the term “wagering requirement” is used in that front-page description, and, in fact, throughout the terms and conditions. Already, things are starting to get more complicated, and you haven’t even clicked through to the main terms and conditions.
