You could also try practising online bingo at a totally FREE site, such as mine! LOL
Alot of bingo sites will have a free pay section, so that you can have a practice and get used to their game. But generally they are a bit quiet and dull, with little chat or 'atmosphere' to speak of, because most people only go in them for a few minutes then decide whether or not to play the real game.
At
www.freebingo.co.uk/?sid56 the entire site is free, and although we have various advertisers which we want players to visit, we do not have a pay to play section. Therefore you can play with lots of other people, ask the about online bingo and have a good chat, and get used to the whole online bingo experience before braving yourself to get out there and risk your cash! LOL
Bear in mind though, that the software used for each bingo website can differ, so if you try different sites you will have to get used to each software.
Have fun!
