It used to be that you couldn't bet on a single line for sports betting in BC, you had to make at least 3 bets (I'm not sure the history of that, it was weird) but it's legal now.
Frankly I don't understand sports gambling, and I don't want to know because I think it would get too tempting to throw $20 here and there and become hooked
I don't have an addictive personality but with the betting apps it seems a little too easy.
