There are no turns, play is simultaneous and frantic.
More cards can be added by either player to common area piles, but they may only stack in numerical order (Ace low) and by matching suit (Ace of Spades, then two of spades, three of spades, and so on). You remove these cards by placing them on top of either your work pile or by creating piles in the common area, starting with Aces. To begin the game, each player turns over the top card of their “Nerts” pile face-up. Leave an open space in between the players and their decks, this becomes the common play area.
