Chat rooms besides the lobby can be somewhat empty at off hours
Friendly CM's. Side games. Evening chats.
I give Bingo Mania an 8. It is a very nice bingo hall and I can recommend it to anyone who's never played there yet. There are a couple of other halls I also like, such as Desperate Housewives, but somehow this one is my favorite where I keep getting back. For one because I am still playing with my free five bucks I got on sign-up. You can find me in the chat mostly on Friday nights. Hope to see you there sometime!
