It seems that there is a lot more activity at the bingo halls for Halloween. Special themed rooms and patterns that start Oct.1 and end Oct. 31. Everyday there's something new somewhere for the spooky players. Some sites encourage you to change your username for the month. A lot of focus on the Halloween theme.
Then, once Christmas time comes along, well, last year it seemed there was less offered than the year before. There are still specials and themes, but the freebies seemed to have been less than with the Halloween gifts. I don't know if this will be the same for me this year, but I'll try to pay more attention to which holiday provides the most benefits for players.
