Goal: First player to reach the target score (default 500) wins.

Hands: Each player gets 10 cards. Draw from the deck or discard pile; discard one card per turn. Build sets (3+ of a kind) and runs (3+ consecutive same suit).

Going out:

• Knock: When your unmatched cards (deadwood) total 10 or less, lay down your melds and knock. The opponent lays off cards if possible. Knocker scores the difference in deadwood values.
• Gin: If you have zero deadwood, call Gin for a 25-point bonus on top of opponent's deadwood.
• Undercut: If your opponent knocks but you have equal or less deadwood, you win and score the difference +25.

Card values: Aces = 1, face cards = 10, others = face value. Enter each round as the points scored by the winner of that hand.
