Hello, I am a PhD in information theory. I have read your requirements for developing a formula for calculating the best choices for selected games, taking into account their price, odds, etc. I am ready to develop an excel spreadsheet (or google sheets doc) with formulas, and a text document with mathematical notations and explanations of those formulas. Mathematical foundation of probability theory had been developed decades ago, so formulas for calculating the odds, permutations, and combinations are in the public domain. We just need to apply them, and I guess you wouldn't have any patent issues with it.
