Difficult, certainly! Where would one begin. Are we talking dogbucks or real cash here? What sort of distance does the game limit itself to?

Am I understanding this right that the aim of the game is to place mines that other players cannot see and get them to walk into them in order to earn a score from the mine. You could put one in a place where nobody can avoid, like the toilet.

Is there an activation delay when placing mines? What if you put a mine down when you were standing next to each other, they’d get hit immediately.

Could be quite interesting the more I think of it. Interesting that you’re actually implementing this, so will have been forced to think through a number of the implementation details inherit to the idea.
