All about Bingo, the social game
Bingo is more than a game to win money on. Bingo is a social event. It's a game where people meet new friends, and genuinely have fun while playing. If anything, there are some websites where betting is a secondary part of the game - the primary function of logging on of an evening being to catch up with online friends. This is what makes bingo stand out from the crowd of other betting forms: in tennis or football betting, people are there for the sole purpose of making a buck. When it comes to bingo, however, there is a true community which has formed around the online game.
Stick with one website
Just as you wouldn't flit between social groups at work, you need to make sure you stay committed to one bingo website. Once you find a site you like, create an account that you intend to stick with. Your username will be displayed during games (assuming your privacy settings allow it to be) and you will become known on chat rooms.
Play at regular times
A lot of people log on to their bingo accounts at certain times on certain days. You will find a spike in activity during the early evening, or late at night - the time when most people are getting home from work and aren't eating. Get into a routine and you will get to know the regulars very quickly.
Be respectful on chat rooms
The worst thing a newcomer can do when they enter a bingo chat room is disrupt the status quo. While you should not be scared of contributing to a conversation, make sure you are sticking to the rules and simply being polite. Avoid SPAM, and don't sent too many smilies to people - you will make friends a lot quicker if you are approachable and don't annoy those who have been around for a long time.
Perhaps the best tip for playing bingo is to have fun. You are there to socialise and bet some money. Think of it in a similar way to going to the pub - you can play some games, spend your money (and hopefully win some back!) and talk to people you will get to know. Enjoy yourself, and you will start to make connections with fellow players very fast.
