My mom sent me an invite to happydaysbingo.com a while back. I'm not much of an online gamer, but thought I would check it out. Because she refered me I got a $10 credit and so did she. Well I went a head and played the 90 ball bingo, which is a little different than regular bingo- to my surprise I won $30! I played a few more games and ended up winning another $10. They also have hourly free games as well that doesn't cost anything to pay. Everytime I've played I've won something. Right now I have about $80 in my account. As I said before, I'm not much of an online bingo person, but this is pretty nice when I'm bored or not working and want something to do that isn't stressful.
