What rules does it use?

Standard two-player six-card cribbage to 121: low card deals first, two cards each to the crib, two for his heels, pegging to 31 with a point for the go and for last card, then hand, hand and crib with one for his nobs. A game won before the loser reaches 91 is a skunk, before 61 a double skunk.

Cribbage online, free

Play cribbage against the computer on a real 121-hole board. When the hands are shown, every count is said out loud the way players say it (“fifteen two, fifteen four, and a pair is six”) with the cards for each point lit up as it's counted.

Not sure which two cards to throw? Suggest a throw works out the average value of all fifteen choices over every possible starter card, and tells you what each one is likely to put in the crib. During the play, Suggest a card shows the card the computer would play in your place.

There's no signup and nothing to download. If you close the page, your game will be waiting when you come back, along with your record: games won, skunks, your best hand and your average hand.

How a deal goes

The deal. Each player gets six cards and throws two face down into the crib, which belongs to the dealer.
The starter. The top card of the deck is turned over. If it's a jack, the dealer pegs two (“two for his heels”).
The play. Players take turns laying cards and calling the running count, which can't pass 31. You score for making 15 or 31, pairs and runs, and a point for the go when your opponent can't play.
The show. The non-dealer counts their hand first, then the dealer counts their hand and then the crib, each with the starter card.

First to 121 wins. The full rules cover every case, the scoring guide explains how to count a hand, and the hand calculator will count any hand for you.

Questions

Is it really free?: Yes. There's nothing to buy and no account. Your game and your record are saved in your own browser and nowhere else.
What rules does it use?: Standard two-player cribbage: six cards each, two to the crib, play to 121. Two for his heels, one for his nobs, a point for the go and for the last card. A win before your opponent reaches 91 is a skunk, and before 61 a double skunk. The computer counts every hand for both players, so there's no muggins.
How good is the computer?: On Sharp it throws the two cards with the best average value over every possible starter, and pegs carefully: it avoids leaving you a 15 or 31 and leads low cards. Casual plays looser and makes mistakes now and then. You can switch in Settings.
Can I play against a friend?: Not yet. For now it's you against the computer.
