Good question, vrukas. Will you also be giving us your top sites and why you like them?
To me most bingo sites are okay. A few ticked me off and I don't play there. Most I don't make deposits with, usually all I can't make deposits.
But when I can deposit, I like the Vista Gaming group sites I belong to: CyberbingoBingo FestBingo Sky
I like them because I can get a great bonus w/o wager requirements, have lots of opportunity to win chat game bbs, lots of free games, good service, ability to deposit/withdraw, easy payouts w/check by courier, good specials, some huge pots, and I like their slots
