Card flipping game mechanic

I don't know if there's any "tips" per se as much as there are ideas on how to implement card flipping as a game mechanic.

But this sounds like a fun exercise...

-Of course there's the memory element which you have already talked about. Place a bunch of cards in a pattern and find pairs or some kind of objective. If the order of the flipped cards is random, it may not lend itself to anything organized like a dungeon or such.

Speaking of which...

-Instead of randomly, maybe a player that is the antagonist places cards facedown for a player that's going through a dungeon, which creates a "fog of war". There's an indie game like this I can't remember...one player plays in the room they are in and the other player sets up the next room in the sequence.

-Of course flipping a card has only 2 states, face-up and face-down, but you might be able to implement orientation as another state, doubling the total states to 4. 1) Face-up and normal orientation ("ready"), 2) Face-up "tapped" ("defending"), 3) Face-down and normal orientation ("knocked out"), and 4) Face-down and "tapped" ("dead", but can be resurrected).

-Maybe if the cards are lined up in a row and the PATTERN of face-up and face-down cards creates a combo...sort of like binary code.

-Then there's flipped as hidden information as in Android Netrunner. One player knows the information they put face-down and it's up to the opponent to "discover" what it is...which could be a trap which leads to...

-The good ol' Yu-Gi-Oh trap mechanic. I've seen your game videos and I'm pretty certain your game was heavily influenced by Yu-Gi-Oh, so I'll just leave this one.

That's all I have for now. It's almost 6am here and I'm sleepy, lol.
