The answer to this question is a little bit more complex than it seems at first glance. While some people believe that trolls are bad luck, others claim that they are actually a form of good luck. It all depends on what you believe.
If you think that trolls are bad luck, then you might not want to play bingo with them around because they could bring you bad luck. However, if you think that trolls are actually a good luck charm, then you could consider playing bingo with them around because they may bring you some extra wins.
Ultimately, it is up to the individual whether or not they believe that trolls are good luck for bingo. However, if you do choose to play with a troll around, just be aware of their reputation and be prepared for any possible bad luck that may come your way.
