betfury bonus terms say no low risk betting, does that mean roulette outside bets too

Reading through these bonus terms and it’s pretty vague how they define “low risk betting.” I know for blackjack it usually means no just flat betting the minimum, or like martingale nonsense, but I’m wondering about roulette. The outside bets, like red/black or even/odd, technically have a much higher chance of winning per spin, so does that count as low risk in their eyes? Or is it more about covering both sides of a bet at the same time?

I’m not seeing any clear examples in their terms, just that “low risk” play can get you in trouble. Anyone here ever actually have a bonus revoked for using outside bets on roulette? Do they track that, or is it only when you do stuff like cover nearly the whole board? Curious what other people’s real experiences have been, not just what the rules say.
