Play continues back and forth until a player 'knocks' or 'goes gin'.Either way, a player always draws one card and discards one card on their turn (it may be the same card for both draw and discard). They may either add the new card to their hand and discard a different card OR they may discard the new card.On a player's turn, they simply choose to draw the top card of the discard pile or the top card of the deck.Otherwise, the game would start with the player who took the card from the discard pile continuing their first turn. If neither player wants it, the non-dealer player would draw from the deck to start the game. If they do not want it, play passes to the other player and they can choose to take the card from the discard pile.
The dealer then discards the top card of the deck to start the discard pile. Shuffle and deal each player 10 cards, one card at a time.
