Many sites have a caller. One of the most important features of online bingo sites is the chat room. You may be sitting at home alone but you can talk to people from around the world. The chat rooms are usually divided into theme or age-specific rooms. You can join in the conversation if you want to or just listen.
Many online bingo friendships happen.
Chat rooms develop regular crowds and favorite topics. Well a lot of people don't live near a bingo hall so online games offer them the opportunity to play. Bad weather makes even the most intrepid bingo player think twice before heading out. Online games are open 24 hours a day. Many people work irregular hours so the fact that online games are always open is a blessing for the shift worker who needs a bingo fix.
