I think UNO would be doable without extra RAM.  Any takers?

The bit packing sounds like a nightmare, though.

Remember that with Uno you can wind up with players with craploads of cards. There is no maximum amount of cards a bad Uno player can get stuck with. Visually you need to be able to cycle through these.

Logically speaking it makes sense to represent each player's hand as a separate array of bytes.

Storing the entire deck's state as one continuous bit-packed array will make it a nightmare during VBLANK. Lots of pointers to bit positions. Lots of seeking and cross-checking all the time. It would take a lot of computing time to, let's say, have the VCS count how many cards each player has in his hand.

I think it's pretty much a given that most of the computation would have to span frames even without an AI mode.
