Your strategy is also my strategy as I think it's less risky but avoid those high win chance games as my experience isn't always pleasant on them. I think they are only an illusion for the players to hope and lose more money.
High chance games are not illusion because some bettors are confidence to put in their risk money into it. A gambling addict sees it as a chance to increase his money and not just the losing aspect. For example if we are to consider some games played by drake then you will see how the chance games work. If you benefit from it then it won't be considered as an illusion because it is a possibility if you have the moral to try your luck but however you don't play such high games if you can't take the loses too.
