The casinos benefit from these promos in two ways. First, their apparent largesse keeps their existing players happy, helping to prevent potential leakage of patrons to other sites. Second, if the promos are sufficiently attractive, they can attract new players to give their games a try. In turn, players both new and old get more fun out of their play and also have more possibilities to reap better rewards.
Of course, since each site tries to outdo the others in these promotions, there are ever more bonuses and freebies waiting for the canny player. There are so many available that it would be impossible to use them all, let alone list them all, but nothing should prevent the savvy gambler picking out the cream of the crop for his use—even if they are present on different casino sites. Below is a selection of some of the  best free bingo cards and bonuses for the month.
