As I said in my intro post, I have never won anything in my life!!!
I play bingo because it's fun, not for the money but it would be nice to win something occasionally. Admittedly I haven't been playing online bingo for that long so maybe things will turn around soon.
I have signed up with astrobingo, cyberbingo, and sunbingo so if I don't come out ahead with one of those I'm going to go crazy, especially when I see others winning hundreds of £££
All those bingo sites have good sign up bonus offers so you should have plenty of money to play around with. Try a few different types of games until you find one you like, I'm sure you'll at least have a few small wins which will keep you playing a while longer (for free).
Anyway, like you said, bingo is fun, you're not just playing for the money.
