Kwiff have a unique approach to free bets where they do not allow you to use the free bet on anything you want and instead allocate you a 'surprise bet'. This is where they place the free bet for you at random. 

Kwiff are notorious for giving out confusing free bets so if you do need to double check the lay market for the bet you have been given please feel free to contact us by email or live chat and we will be happy to help you with that.
