The 7th bet feels like a trap to keep you playing. And 40x wagering is pretty big, imo
I didn't find 40x wagering as a requirement, have you experienced this or are you just guessing?
Just guessing imo as he may think that all promo usually comes with 40x wagering requirement so he generalizes it

The fact is that there is no written terms about wagering requirement for this freebet promo, means that it should be zero wagering requirement. It is also rare to see similar promo which come with 40x wagering requirement because it will be something unattractive if casino offer freeebet with such high wagering requirement.
