As we get further down our Top 100 of Bingo Sites, the brands may become less familiar to you. Some of the sites will be new or they'll not be the biggest of brands. This shouldn't put you off investigating them! Sometimes a smaller independent site with fewer players can appeal to people who enjoy a closer community.
Smaller sites also tend to like to entice new players with big offers - especially at launch. With big brands you generally find more players and bigger promotions. However you can often get some free games once you've registered and deposited.
A handful of bingo sites and many slot sites now offer new players free spins at registration and bonus spins on first deposit. These often will generate you a guaranteed bonus. However as with games bonus offers be careful. Wins from free spins will usually come with a larger wagering term - plus you may be limited on how much you can win.
