The question is very misleading. There are very little details and you end with asking for an opinion. It sounds to me like a question about how much risk the person is willing to take rather than a math question. The "What are you willing to pay to play this game?" really needs to be replaced with something else. I would never associate this with a math question unless risk tolerance was included in the details. Any questions I might ask would not clue me into it being a math question either.
