I've never done this, although after reading this I'm interested in trying it, so far I've only done multi bets on football matches and always separated them if I wanted to bet on other games.
But it's worth a try, especially as I also understand in some matches. What is clear is that at the moment I have never done it, but I think I will do it in the future, to be precise, I am still thinking about which matches are worth doing multi bets on different games.
