Games with a high number of players

A high number of players increases the prize pool and makes winning very satisfying when it happens, the major drawbacks are that winning is less regular

Games with a high prize fund

A high prize fund tends to attract more players and often people are tempted to purchase more than one ticket to increase win ability

A popular bingo site e.g. Wink...

Popular established online bingo sites tend to promote more often and use a lot of gimmicks to try and get people to stay, they are often reputable so trust and fairness in the site is guaranteed as is reputation which is the most important asset they hold.  The only real drawback is that large established sites tends to lose their personality and you are less likely to don't bump into the same people on the forums.

An independent bingo site e.g. Fruit Bingo

Independent sites vary and many are part of larger networks to increase the overall prize fund.  Dependent on the network, some of the sites like fruitbingo.co.uk have more informal chat rooms and you are more likely to meet people and speak with them and see bump into them again when you return to the site.  Independent sites tend to be a little more personable.  They tend to appeal to different audiences rather than the mass market, this is why it is good to go to an independent bingo comparison site Bingosupermarket.com to share the benefits and help people to find a website that suits you.
