Gin Rummy vs computer. Know when to knock.

Choose a practice partner

This button opens Vs computer with your saved difficulty. To change it, press Vs computer and choose Easy, Medium or Hard. Easy sometimes makes loose discards. Medium weighs deadwood and partial melds. Hard also considers publicly known pickups and available completing cards. Every level sees only its own hand and public cards; none reads your hand or the stock order. Hard is a heuristic opponent, not a promise of perfect play.

Build melds. Reduce deadwood. Choose your moment.

Each player receives ten cards from a 52-card deck without jokers. Make sets of three or four equal ranks, or runs of at least three consecutive cards of one suit. Aces are low; Q–K–A is not a run. A card can belong to only one meld.

Player 1 starts the first hand. The non-dealer may take the opening upcard or pass; the dealer then gets the same choice. If both pass, the non-dealer must draw from stock. After that, draw from either pile and discard one card. An upcard cannot be returned on the same turn.

Unmatched cards are deadwood: an ace counts 1, picture cards 10, and other cards their number. Select a card to preview the total after discarding. The table automatically finds a disjoint arrangement with the lowest deadwood; green marks show cards in melds.

Knock with 10 or fewer deadwood after discarding. With zero, announce gin: score 25 plus the opponent’s deadwood, without layoffs. After a regular knock, the defender automatically chooses melds and adds eligible cards to the knocker’s melds. The knocker scores the difference only if their deadwood is lower. A tie or lower defender total is an undercut: the defender scores 25 plus the difference.

The first player to reach 100 points wins. Next hand keeps scores and alternates the dealer after a scored hand. Two remaining stock cards after a discard without knocking end a drawn hand; no points are awarded and the dealer stays. This version has no Big Gin, box bonuses or end-of-match bonuses.

On one device, hands disappear between players: pass the device before pressing Reveal my hand. In computer mode, your own cards stay visible. In a private room, each browser receives only its own hand and public information; hidden cards and stock order are not sent to the other player.

Watch what leaves the hand

A pair or two neighboring suited cards can grow into a meld. An isolated picture card costs ten if the opponent ends the hand. Notice the cards your opponent picks up; discarding a nearby card may help them. Knocking early can score, but leaves room for an undercut.
