This is quite funny honestly, okay let’s imagine the casino stating a free bet offer with another paragraph stating you have to make $5 wager in the last 7 days first before earning any free bet. It’s doesn’t make any sense putting everything out except the casino wants to and it’s never a big deal basically every free bet comes with a requirement besides this is not the first, it’s all about risk like you can decide to risk $5 along side earning a $5 free bet or let go of the bonus then wager what you can afford to lose. I’m not surprised, I expect every casino to attach a requirement before a bonus else they’re on the losing side.
