Ok, that's another important missing detail: that you can win with fewer than 24 of the squares covered.

comment How do lambda calculus most basic definitions work?
An aside on "Shouldn't $\lambda f.\lambda x\;x$ be a function with two arguments, one of which is a function?": it is simultaneously a value, a function with one argument which returns a function with one argument, and a function with two arguments. In lambda calculus functions are first-class objects and everything is a function.

@Mr.G, not starting with fresh cards would certainly introduce a bias. Ah, so "the cards are cleared" means "people keep the same cards, but reset their contents"? That's the kind of important detail I was talking about - I would assume that everyone would have to have fresh cards.

There is nowhere near enough detail to begin answering this question. The most important detail is: why would the previous winner be advantaged or disadvantaged? Isn't each game independent?

It's a truncated octahedron, not a truncated cube.

Extend it to hexagons and it doesn't go infinite.

Degree 6 or degree 8? Your diagram doesn't seem to fit your description.
