👉 “Identical cards” are cards that have the same number AND the same color.
For example, two “yellow 4s” are identical, but a “yellow 4” and a “purple 4” are not.

👉 Yes. In a 2-player game, a central river of cards is placed face down with one visible card on top of each pile:

Each player still starts with 8 cards in hand.

During the game, players can use the visible cards from the river for attack or defense.

Once a card is used, the hidden card underneath is flipped and becomes available.
➡️ This allows players to play more than 8 cards total in a match.
