Monopoly

For the life of me I cannot win a game of monopoly. No matter what I do. When I buy the Blue properties I lose, when I buy homes and hotels, I lose. Even when I have the Orange properties I still lose, really no matter what I do I end up losing, I won one time three months ago. That's history now, I've been playing Monopoly this past week with my sister, and she's one every single game, and then I played with my mom and sister and I still ended up losing. I even used the tricks I learned, for the most part, and I still lost. It's really getting very annoying.
