How to play Gin Rummy
Get your hand into sets and runs, then knock before the other player does.
These are the rules for the PlayBurst version. Other versions may play differently.
Rules and controls
1. Draw and discard
Take the top of the stock or the discard pile, then throw one card away.
2. Build melds
A meld is three or more of a rank, or three or more in sequence in one suit.
3. Knock
When your unmatched cards add up to ten or less, press Knock and then throw the card you are knocking on. Gin is all ten cards melded, and scores twenty-five over the other hand.
4. Laying off
When a knock is not gin, the other player first lays any loose card that fits onto the knocker's own melds, and only counts what is left.
5. The undercut
If the player you knocked on has as little deadwood as you or less, they take the difference and twenty-five instead. Knocking on ten is not always worth it.
