Run and Set

A two-player rummy game against the computer. Build sets and runs, knock when your leftover cards are low, and race to 50 points.

How to play

Each player holds 10 cards. On your turn, take the top discard or draw from the stock, then throw one card away.
A meld is three or four cards of the same rank, or three or more in a row in the same suit. Aces are low. Melds are shown with green borders.
Cards outside melds are deadwood. Face cards count 10, aces count 1, and the rest count their number.
Knock when your deadwood is 10 or less. If it is lower than the computer's you score the difference. Gin, with no deadwood, adds a 25 bonus. First to 50 wins the match.

Do not take the discard unless it completes a meld or clearly lowers your deadwood.
Throw high cards you cannot meld early. A king left in your hand costs 10 points if the computer knocks.
If the computer knocks with low deadwood you may undercut it. Matching or beating its count scores you the bonus.
The stock running low ends the hand as a draw, so do not wait too long to knock.

Can I lay off cards onto the knocker's melds?: No. This version skips laying off to keep each hand quick.
What is an undercut?: If the knocker's deadwood is not lower than the other player's, the other player wins the hand and gets a 25 point bonus.
