The ace can be combined with the deuce but not with the king (K). The game consists of players grouping the 10 cards in their hand to make minimum combinations of three cards of the same rank or runs of the same suit. The game continues, with each player in turn being able to take the top card off the stock deck or the discard pile, then discarding a card, but which may not be the same card that they just picked up from the discard pile. From the first draw onward, a player must pick up a card from either the stock or the discard pile at the beginning of their turn and remove one card from their hand to the discard pile at the end of their turn. If they also choose to pass, the other player begins the game by taking the top card from the stock pile. If they choose to pass, the dealer has the choice to take the top card of the discard pile. The player opposite of the dealer has the option to play first by taking the top card of the discard pile. In the following games, the player who wins the previous game becomes the dealer. The top card of the stock deck is placed face up next to it to start the discard pile.

The player who draws the highest card chooses where to sit and deals out ten cards to each player, one by one, leaving the deck with the remaining cards in the center of the table.

The deck is spread out on the table and each player takes a card. Each player uses their hand to form combinations of three or more cards, to get more than the 100 points required to win the game before their opponent does so when played over several hands. Gin Rummy or Gin is a traditional card matching game that requires 2 players and a standard 52 playing card deck with Kings high and Aces low.
