Gin Rummy

Deal ten cards to each player and place the remaining deck face down, turning the top card face up beside it.

On each turn, draw either the top card of the deck or the face-up discard, then discard one card from your hand.

Arrange your hand into sets of three or more matching cards, or runs of three or more consecutive cards in the same suit.

When your unmatched cards total ten points or fewer, you may "knock" and lay down your hand to end the round.

Compare hands, score the difference in unmatched card values, and play multiple rounds until a player reaches an agreed target score.
