Squidoo banned online gaming pages a long time back. I used to have a few on there and they were all taken down. As for Hubpages, unless you’ve got a good user score, you won’t get link juice and I think Google are all across its use for links so any you do get is negligible. Also, they don’t like online gaming content either. You can do it, but you have to be very careful how. IE, Online Bingo – do a piece on the history of bingo numbers in bingo halls.
