Still increasing in popularity amongst all online casino games is online bingo. Bingo used to be the night out for ladies but these days bingo online starts from as early as 07:00 in the morning and goes on until late in the night; as long as there are folk around who are wanting to play and it is certainly no longer a female domain as many men have also found the excitement of waiting for that last number irresistible. Online Bingo is usually played in either a 90 ball format or a 75 ball format although both Ladbrokes and Paddy Power for example also have 80 ball games; the principle remains the same for all games but there are differences. A 90 ball game in online bingo rooms normally has bingo cards with three rows of 5 numbers (15 numbers in total) and there will be three prizes up for grabs in each game which are for one line complete, two lines complete and the full house. 75 ball online bingo games can either be pattern games or regular games. In a pattern game the bingo card will have 25 numbers displayed in a 5 by 5 pattern with the central square being a free one; each game will have a winning pattern displayed and those are the number that you need to achieve on your bingo card to win. In a regular 75 ball online bingo card there can be up to 5 prizes per game.
