Thank you for the clarification, I usually use sports betting methods, so it would be easier for me to meet this wagering requirement.
The rules are most favorable for sports bettors, that's true. The multiplier is three times higher than for slot games, even though slots are more difficult to make a profit with. I tried to check if there are minimum odds you need to respect for sports betting to meet the wagering requirements but the FAQ doesn't mention it. I haven't checked the T&C, perhaps it provides more clarity.
