31 Card Game (Thirty-One)

Yes, here, against the computer in your browser with no download or account. Pick 2 to 7 players and a skill level.

On your turn, instead of drawing, from your second turn of a round onward, and only if nobody has knocked yet. Everyone else then gets one more turn before the showdown.

Yes: three cards of the same rank score 30.5, which beats any ordinary 30 and loses only to 31. The host can set it to 30 or switch it off.

The round ends immediately, even before you discard. You win the round and every other player loses a life. This also applies if you are dealt 31.

The lowest hand at the showdown loses one life. If the knocker is alone at the bottom, they lose two. If the knocker ties for lowest, the knocker is safe and the others tied lose a life. Any other tie costs every tied player a life. The host can switch to “all tied lose”, which also takes lives from a tied knocker.

Three. The host can choose four or five. At zero you are out, and the last player left wins.

Two to seven. With more players, knock earlier: more hands means someone is more likely to be lower than you.

Yes. Scat and Blitz are other names for the same draw-and-discard game; “Blitz” is also what we call an instant 31.

Aces 11, face cards 10, number cards face value, counting only cards of one suit. The table shows your best suit total as you play.

Easy always draws from the stock and knocks only on 27 or more. Standard takes any discard that raises its hand and knocks at a fixed bar that drops as the round goes on. Expert plays like Standard with two differences: it knocks when its hand is clearly ahead of what the others usually hold after the turns they have had, and it takes a discard only when it beats an average card from the stock. Against three Standard players, Expert wins about 38% of four-player matches, Standard about 26% and Easy about 4%. No level sees your hand or the stock.

With four players, about eight or nine rounds, and you get about three turns a round (a little more against Expert, which knocks later). Two players finish in three or four rounds. Your match is saved in this browser, so a reload brings you back to the same turn.

Yes. D draws from the stock, T takes the discard, K knocks, and 1 to 4 discard the card in that place in your hand. H gives a hint and U takes back your last move in practice, until you draw from the stock.
