Bingo is one of the easiest games to play and the online version is no different. Today online bingo is a multi billion dollar business. There is a great variety of games to play to suit just about every player. Some inexpensive game rooms allow players to enter the game and play for just 10 cents. Some online bingo rooms only allow players to purchase the same number of cards so players are not competing against those who buy many cards for the same game. To win the largest prizes, users must fund an account, but free bingo games are also available offering players a way to win smaller amounts of money with no risk. Some online casino sites offer bingo with sandbox play which allows beginners to get the hang of the system without a cash investment. Unlike balls used in regular bingo halls, online bingo sites use a random number generator. The actual bingo play works almost exactly like playing any other kind of online casino game with everything being virtual. One important feature of online bingo halls is the chat functionality which fosters a sense of community between players. Whereas in land-based bingo talking is strictly forbidden during a game, it is encouraged in online bingo. It is customary for players to congratulate winning players with comments like WTG (Way To Go). The CM (Chat Monitor) works for the bingo site as the host of a chat room. It welcomes players, creating a friendly and communal atmosphere in the room. Playing bingo online, players can also make use of optional features which make playing easier, such as auto-daub. Auto-daub automatically marks off the numbers on cards as they are called, so players don't have to. On a busy site, and on a lucky day, you can expect to win roughly four to eight times the amount it costs to buy a bingo ticket.
