A) Yep, that's the way to go. Private state variables all the way! Keeps the game fair and square.

C) Haha, that's true! You can't really hide anything on the blockchain. Might as well just embrace the transparency!

B) That's an interesting approach, but I'm not sure it's the best option. Keeping everything within the smart contract seems more straightforward.

B) with external contracts holding those values. This way we can make sure that the information flow is following a clear logic and nobody else can access this information.
