Gin Rummy

Take one card on your turn, from the stock or from the face-up pile, and then put one down. You cannot put back the card you just took off the pile. Sets are three or four of a rank, runs are three or more of one suit in order with the ace low, and everything left over is deadwood.

Pick the card you want to put down, then choose whether it is a plain discard or a knock. The knock button turns on once that card would leave you with 10 deadwood or less, and it says what you would be left holding. Knock with nothing left over and that is gin.

A knock stops the round: both hands turn over, the other player lays what fits onto your melds, and the points are worked out from there. Then you both press "Next deal" for the next one. Chat is always on at the table, and voice only if the host switched it on when they made it.
