The two-player card game
Meld it. Knock. Go gin.
Draw, discard and build your ten cards into sets and runs. Knock once what's left counts 10 or less, or hold out for gin and catch your opponent with a handful.
Against a bot, no account: your browser deals, and the bot plays in it.
How a deal goes
Ten cards each, one turned up beside the stock, and the same two choices every turn.
Draw
Take the top card of the stock, or the card your opponent just threw. Then throw one card face up.
Meld
Three or four of a rank make a set; three or more in sequence in a suit make a run, ace low. Everything else is deadwood, and counts against you.
Knock
With 10 or less in deadwood, knock and lay your hand down. With none at all it is gin, and worth 25 more.
The showdown
A knock is a bet.
Your opponent lays down their melds and adds what they can to yours. If they still count more than you, you score the difference. If they don't, it's an undercut: they score it, and 25 more.
The knocker: deadwood 6
The defender, after laying off: deadwood 30
4 levels
From a beginner who blunders to a bot that never slips.
Choose before the deal. Every bot follows the rules and sees what a player at a real table would: its own hand, and the cards played face up.
- 1
Beginner
Forgets what has been thrown, and one move in 3 is a random one.
- 2
Casual
Plays sensibly, but one move in 8 is still a random one.
- 3
Steady
Remembers what you took and what you threw, and only one move in 20 is a random one.
- 4
Sharp
Never slips: it keeps its pairs early, counts its deadwood late, and won't throw you a card you can use.
+18
points a deal, on average, won by the Sharp bot over the Beginner.
300 deals, each played twice with the seats swapped, so the cards cancel out and only the play is left.
Everything a game needs
Standard or Oklahoma
Knock with ten or less, or let the first upcard set the limit and double the deal on a spade. Play to 50, 100 or 150.
Scored the real way
Gin and undercut bonuses, a box for every deal won, a bonus for the game, and the lot doubled for a shutout.
A fair shuffle
Every deal is shuffled from your browser's cryptographic random source, and the bot only ever sees its own cards.
Made for a phone
The table fills the screen, your hand sorts itself into melds as you draw, and you can drag any card where you want it.
